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).

Re: no repeat sequences in exons of genes?

... LINES can use reverse transcriptase to insert a mRNA back into DNA and cause diseases Dude, its sooo much more likely that the mRNA so retrotransposed ... it had stops (stop codons) , then that would be the end of the protein synthesis at that first stop codon, unless amber/opal/ochre tRNA's are ...

Re: Features of the leading strand synthesis on DNA ends

Which DNA polymerase are you referring to? Eukaryotic chromosomes have telomeres which shorten with each replication, a possibly source of aging as cells with short telomeres are targets of apoptosis (programmed cell death). ...

Features of the leading strand synthesis on DNA ends

Dear colleagues! Help me please with one question. Have the DNA polymerase can complete leading-strand synthesis in the ends of DNA, or no, leaving 5'-overhangs? I am interesting in the problem of DNA ...
