Because of the huge interest in the Confucius family tree, there was a project in China to test the DNA of known family members.

Because a person's DNA contains information that has been passed down relatively unchanged from early ancestors, analysis of DNA is sometimes used for genealogical research.

Because Formalin-fixed, paraffin-embedded ( FFPE ) tissues may be stored indefinitely at room temperature, and nucleic acids ( both DNA and RNA ) may be recovered from them decades after fixation, FFPE tissues are an important resource for historical studies in medicine.

Because Luthor now sees Superboy as a failed experiment of using the " wrong alien DNA ," he and Brainiac create another binary clone with their own genetics for another plan against the entire House of El.

Because DNA contains four nucleotides, the total number of possible codons is 64 ; hence, there is some redundancy in the genetic code, with some amino acids specified by more than one codon.

Because of its tight conformation, supercoiled DNA migrates faster through a gel than linear or open-circular DNA.

Because it can perform the tasks of both DNA and enzymes, RNA is believed to have once been capable of supporting independent life forms.

Because reverse transcription lacks the usual proofreading of DNA replication, a retrovirus mutates very often.

Because cells and more importantly the DNA can be damaged, this ionization can result in an increased chance of cancer, and thus " ionizing radiation " is somewhat artificially separated out of particle and electromagnetic radiation, simply due to its larger potential for biological damage per unit of energy.

Because of the key nature of DNA to living things, knowledge of DNA sequence may come in useful in practically any biological research.

Because it normally has a positively charged nitrogen at its end, lysine can bind the negatively charged phosphates of the DNA backbone.

DNA methylation frequently occurs in repeated sequences, and helps to suppress the expression and mobility of ' transposable elements ': Because 5-methylcytosine can be spontaneously deaminated ( replacing nitrogen by oxygen ) to thymidine, CpG sites are frequently mutated and become rare in the genome, except at CpG islands where they remain unmethylated.

Because DNA methylation and chromatin remodeling play such a central role in many types of epigenic inheritance, the word " epigenetics " is sometimes used as a synonym for these processes.

Because of the lack of nuclei and organelles, mature red blood cells do not contain DNA and cannot synthesize any RNA, and consequently cannot divide and have limited repair capabilities.

Because A, G, C, and T appear in the DNA, these molecules are called DNA-bases ; A, G, C, and U are called RNA-bases.

Because the desired type of DNA recombination is a rare event in the case of most cells and most constructs, the foreign sequence chosen for insertion usually includes a reporter.

Because all mitochondrial DNA ( mtDNA ) is generally passed from mother to offspring without recombination, all mitochondrial DNA ( mtDNA ) in every living person is directly descended from hers by definition.

Because of this and because the mutation rate of animal mtDNA is higher than that of nuclear DNA, mtDNA is a powerful tool for tracking ancestry through females ( matrilineage ) and has been used in this role to track the ancestry of many species back hundreds of generations.

Because of the intense personality conflict developing between Franklin and Wilkins, Randall divided the work on DNA.

Because Y chromosomes are smaller than X chromosomes, sons inherit a slightly smaller proportion of the genome from their fathers — half of the autosomal DNA, plus a Y chromosome ) than daughters ( half of the autosomal DNA, plus one X chromosome — which is in turn slightly smaller than the proportion that children of either gender inherit from their mothers — half of the autosomal DNA, plus one X chromosome, plus all mitochondrial DNA ).

Because Tay – Sachs disease was one of the first autosomal recessive genetic disorders for which there was an enzyme assay test ( prior to polymerase chain reaction testing methods ), it was intensely studied as a model for all such diseases, and researchers sought evidence of a selective process.

Because DNA synthesis cannot start de novo, an RNA primer, complementary to part of the single-stranded DNA, is synthesized by primase ( an RNA polymerase ):

Because the binding of the polymerase to the template is the rate-limiting step in DNA synthesis, the overall rate of DNA replication during S phase of the cell cycle is dependent on the processivity of the DNA polymerases performing the replication.

Because the 5 ' → 3 ' exonuclease activity of DNA polymerase I from E. coli makes it unsuitable for many applications, the Klenow fragment, which lacks this activity, can be very useful in research.

Because of the simplicity of Pol I transcription, it is the fastest-acting polymerase.

Because of the specific transport mechanisms, only limited amounts of chromium ( III ) enter the cells.

Because gallium ( III ) and ferric salts behave similarly in biological systems, gallium ions often mimic iron ions in medical applications.

Because Moshoeshoe II initially refused to return to Lesotho under the new rules of the government in which the King was endowed only with ceremonial powers, Moshoeshoe's son was installed as King Letsie III.

Because of the many threats against Maria and Alexander III, the head of the security police, General Cherevin, shortly after the coronation urged the Tsar and his family to relocate to Gatchina Palace, a more secure location 50 kilometres outside St. Petersburg.

Because of the similarity of the names Marinus and Martinus, Popes Marinus I and Marinus II were, in some sources, mistakenly given the name Martinus ( and were then listed respectively as Martinus II and Martinus III ).

Because of the similarity of the names Marinus and Martinus, Popes Marinus I and Marinus II were, in some sources, mistakenly given the name Martinus ( and were then listed respectively as Martinus II and Martinus III ).

Because Sergius III had reputedly ordered the murder of his two immediate predecessors, Leo V and Christopher and was the only pope to have allegedly fathered an illegitimate son who later became pope ( John XI ), his pontificate has been described as " dismal and disgraceful ".

Because Otto III was still a child, his grandmother Adelaide of Italy took over the regency until Otto III became old enough to rule on his own.

Because Otto III was still a child ( only eleven when his mother died ), his grandmother, the Dowager Empress Adelaide of Italy, became regent, together with Archbishop Willigis of Mainz, until he became old enough to rule on his own in 994.

Because of the probability of the escalation of the conflict, Léopold III abdicated on July 16, 1951 in favour of his 20-year-old son Baudouin.

Because of these successes, the representatives of nobility and clergy ( Stamenti ) formulated five requests addressed to the King Victor Amadeus III of Sardinia, but they got a refusal.

He famously complained in a letter to Innocent III " Because I am a Welshman am I to be debarred from all preferments in Wales?

* Because of his administrative and constitutional reforms in Carthage, Hannibal becomes unpopular with an important faction of the Carthaginian nobility and he is denounced to the Romans for inciting the Seleucid king Antiochus III to take up arms against the Romans.

Because of this Polish Prince Bolesław III was preparing a massive penal expedition that may have spoiled all the earlier accomplishments of missionary work by Bishop Otto.

Because diplomacy and negotiation had failed, Edward III would have to back his claims with force if he was to claim the throne.

Because of the crusading appeal made by Pope Eugene III and his representative Nicholas Brakespear ( the future Pope Hadrian IV ), the siege received the aid of crusaders from multiple nationalities ( Genovese, Anglo-Normans, Normans, Southern-French, Germans, Flemish and Dutch ), who were on their way to the Holy Land.

Because none of the sons of Victor Amadeus III themselves had sons, Charles Albert was throughout his life known to be their likely successor on the throne of Sardinia.

Because of its strategic location, in 1343 king Casimir III signed there a peace treaty with the Teutonic Order.

Because the star is not completely metal-free, it does not belong to the first generation of stars ( the hypothetical Population III ).

Because of the marriage of Beatrix of Heusden with Zeger III ( viscount of Ghent ) in 1212, the seat of the viscountship of Ghent moved to Heusden.

Because his predecessor had failed to meet all of the specific costs of the civil government in accordance with the previous arrangement, it was decided that in return for George III surrendering the hereditary revenues from the Crown Estate to Parliament for the duration of his reign, Parliament would assume responsibility for most of the costs of the civil government.

Because Vice City was built upon Grand Theft Auto III, the game follows a largely similar gameplay design and interface with GTA III with several tweaks and improvements over its predecessor.
