Some specific sequences of noncoding DNA may be features essential to chromosome structure, centromere function and homolog recognition in meiosis.

Some noncoding DNA sequences are genetic " switches " that regulate when and where genes are expressed.

Some noncoding DNA sequences determine where transcription factors attach.

Some of the key topics that spurred development of the field have been the evolution of enzyme function, the use of nucleic acid divergence as a " molecular clock " to study species divergence, and the origin of noncoding DNA.

Some systems have proposed as many as 90 subspecies, while recent DNA analysis has identified as few as five clades.

( Some exceptions exist ; for example, deoxyribose, a component of DNA, has the empirical formula C < sub > 5 </ sub > H < sub > 10 </ sub > O < sub > 4 </ sub >.

Some mitochondrial proteins are made inside mitochondria and are coded for by mitochondrial DNA.

Some newer agents do not directly interfere with DNA.

Some genetic disorders are passed down from the parents ' genes, but others are always or almost always caused by new mutations or changes to the DNA.

Some adducts may also result in the depurination of the DNA, it is however uncertain how significant such depurination as caused by the adducts is in generating mutation.

Some alkylating agents may produce crosslinking of DNA.

Some metals such as cadmium, chromium, and nickel may alter the fidelity of DNA replication.

( Some critics thought the PBS series did not sufficiently explain the limitations of DNA testing for assessment of heritage.

Some tribes have begun requiring genealogical DNA testing, but this is usually related to an individual's proving parentage or direct descent from a certified member.

Some are long-chain biopolymers, and these include peptides, DNA, RNA and the polysaccharides such as starches in animals and celluloses in plants.

Some biological polymers are composed of a variety of different but structurally related monomer residues ; for example, polynucleotides such as DNA are composed of a variety of nucleotide subunits.

Some viruses use RNA as their genetic material, rather than DNA.

Some of these enzymes are used in molecular biology ( for example, heat-stable DNA polymerases for PCR ), and in washing agents.

Some transcription factors, so-called pioneering factors are still able to bind their DNA binding sites on the nucleosomal DNA.

Some algorithms are useful only when the characteristic data are molecular ( DNA, RNA ); other algorithms are useful only when the characteristic data are morphological.

Some large intergenic regions contain repetitive DNA sequences.

Some inventions and discoveries to come out of Berkeley Lab include: " smart " windows with embedded electrodes that enable window glass to respond to changes in sunlight, synthetic genes for antimalaria and anti-AIDS superdrugs based on breakthroughs in synthetic biology, electronic ballasts for more efficient lighting, Home Energy Saver, the web's first do-it-yourself home energy audit tool, a pocket-sized DNA sampler called the PhyloChip, and the Berkeley Darfur Stove, which uses one-quarter as much firewood as traditional cook stoves.

Some retroviruses are transmitted in the germ line, i. e. their genetic material is integrated into the DNA of either the ovum or sperm.

Some supporters of Anderson's claim acknowledged that the DNA tests proving she could not have been the Grand Duchess had " won the day.

Some of the sequences in Venter's genome are associated with wet earwax ,< ref >

Some editors and translators argue that the received text is so corrupted ( from originally being written on one-line bamboo strips linked with silk threads ) that it is impossible to understand some chapters without moving sequences of characters from one place to another.

Some macro systems are self-contained programs, but others are built into complex applications ( for example word processors ) to allow users to repeat sequences of commands easily, or to allow developers to tailor the application to local needs.

Some evolutionary biologists, for example Allan Wilson, have proposed that evolution in promoter or regulatory regions may be more important than changes in coding sequences over such time frames.

Some recognize palindromic sequences while others have asymmetric recognition sites.

Some legends state that Virgil, fearing that he would die before he had properly revised the poem, gave instructions to friends ( including the current emperor, Augustus ) that the Aeneid should be burned upon his death, owing to its unfinished state and because he had come to dislike one of the sequences in Book VIII, in which Venus and Vulcan have sexual intercourse, for its nonconformity to Roman moral virtues.

Some last laugh sequences featured other Muppets on the balcony.

Some of the techniques that can be applied in a more limited scope, such as macro compression ( which saves space by collapsing common sequences of instructions ), are more effective when the entire executable task image is available for analysis.

Some sequences may have no biological function for the organism, such as endogenous retroviruses.

Some control sequences are special characters that always have the same meaning.

Some events connect the game to the movies Star Wars Episode V: The Empire Strikes Back and Star Wars Episode VI: Return of the Jedi, such as sequences that track the Rebellion's situation after the Battle of Hoth, as well as the theft of the Shuttle Tyderium.

Some species ( noted below ) had differing relationships indicated by their nuclear DNA ( paternally inherited ) and chloroplast DNA sequences ( maternally inherited ), a clear indication of likely hybrid origin.

Some positive comments from critics included commendation for the quality and intensity of its action sequences, and its intelligence.

Some new sequences have been added ( e. g., an introduction to act three, in which Tim, the Company Stage Manager, and Poppy, the Assistant Stage Manager, make simultaneous apologies — the former in front of the curtain, the latter over the PA — for the delay in the performance ).

Some interior sequences in Harry Potter and the Chamber of Secrets were filmed at Lacock, including the cloister walk ( illustrated, left ) where Harry freed Dobby.

Some of the fight sequences were filmed at The Blue Horizon in Philadelphia, a venue which was a mecca for boxing in the city during the 1970s.

* Some of the sequences showing the testing of Upkeep in the film are of Mosquito fighter-bombers dropping the naval version of the bouncing bomb, code-named " Highball ", intended to be used against ships.

Some polynomial sequences arise in physics and approximation theory as the solutions of certain ordinary differential equations:

Some speculated that these features make it easy for humans to " read " ( predict possible variations ) long sequences of moves, while being irrelevant to a computer program, but no rigorous cognitive neuroscientific evidence currently exists to back this hypothesis.

Some tracks on the album are more location / episode-specific or for special sequences.
