M. Muñoz, he produced an active cell-free system, a first in scientific research.

During their synthesis the mRNAs are processed to introduce a 5 ' cap and a 3 ’ polyadenylated tail to each of the molecules.

During this stage new organelles are being synthesized, so the cell requires both structural proteins and enzymes, resulting in a great amount of protein synthesis and a high rate of metabolism in the cell.

During this time, the two worked on the synthesis of substituted phenyl esters of oxalic acids.

During DNA synthesis, a DNA / RNA hybrid is formed as a replication intermediate and must be cleaved by RNase H before the process can continue.

During protein synthesis, tRNAs with attached amino acids are delivered to the ribosome by proteins called elongation factors ( EF-Tu in bacteria, eEF-1 in eukaryotes ), which aid in decoding the mRNA codon sequence.

During synthesis, alternative nucleotides or codons are incorporated into the DNA sequence at specific positions.

During karyorrhexis, endonuclease activation leaves short DNA fragments, regularly spaced in size.

During cell division these chromosomes are duplicated in the process of DNA replication, providing each cell its own complete set of chromosomes.

During prophase I, DNA is exchanged between homologous chromosomes in a process called homologous recombination.

During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA as needed.

During cell division these chromosomes are duplicated in the process of DNA replication, providing each cell its own complete set of chromosomes.

During conjugation, a pilus emerging from donor bacterium ensnares the recipient bacterium, draws it in close, and eventually triggers the formation of a mating bridge, which establishes direct contact and the formation of a controlled pore that allows transfer of DNA from the donor to the recipient.

During the early 1970s, retroviruses and reverse transcriptase were discovered, showing for the first time that enzymes could copy RNA into DNA ( the opposite of the usual route for transmission of genetic information ).

During cell division, DNA is replicated and can be transmitted to offspring during reproduction.

During the early 1950s, while Watson and Crick were determining the structure of deoxyribonucleic acid ( DNA ), they made use of unpublished X-ray diffraction images taken by Rosalind Franklin, shown at meetings and shared with them by Maurice Wilkins, and of Franklin's preliminary account of her detailed analysis of the X-ray images included in an unpublished 1952 progress report for the King's College laboratory of Sir John Randall.
