relatively low percentage of full-length sequences after desalting. Additionally, failure sequences occur at the 5' end of the sequence as oligos are generated from 3' to 5' end. Therefore, restriction sites introduced at the 5' end of primers can be compromised, resulting in missing bases....
bases. DNA serves as a template for creating a complementary DNA strand during replication, repair, and recombination, and a complementary RNA strand during transcription. In some cases, RNA also serves as a template for nucleic acid synthesis, for example, for generation of telomere DNA at the...
states that the new method gives us the ability to have a ten-fold improvement in the amount of DNA produced from a single DNA sequence. A DNA sequence is composed of units which are called bases. The sequence puts the bases in chronological order for it to code correctly. ...
damaged bases.(a)Reaction of adenine removal from OG:A mispairs catalyzed by MutY. Subsequent processing by other enzymes of the BER pathway results in eventual restoration of the correct G:C base pair [9]. (b) Diversity of bases recognized by different 4Fe–4S cluster-containing glycosylase...
