Dna synthesis

Dna synthesis

(Science: molecular biology) The linking together of nucleotides (as deoxyribonucleotide triphosphates) to form dna. In vivo, most synthesis is dna replication, but incorporation of precursors also occurs in repair. In the special case of retroviruses, dna synthesis is directed by an rna template (see reverse transcriptase).

Protein synthesis during S phase

Are you sure there is no protein synthesis during S phase? If it is so, I'd say it's because the DNA is busy with all the replication and thus cannot lose time with transcription.

... on. My initial intention was to examine the claim, that the results of DNA studies confirm Darwinian evolution. I think there is no point in discussing ... recognize how big this problem really is. Many genes required for photosynthesis have been found in the genome of a sea-snail (Elysia chlorotica)6, ...
