Uracil-DNA Glycosylase (UDG)

... Protocol: Preventing Carry-over Contamination with Uracil-DNA Glycosylase In PCRs even minuscule amounts of a contaminant can be amplified and lead to a false positive result. Such contaminants are often come from previous PCRs (carry-over contamination). Therefore, researchers have developed method ...

... During translation, a small ribosomal subunit attaches to a mRNA molecule. At the same time, an initiator tRNA molecule recognizes and binds to a specific codon sequence on the same mRNA molecule. A large ribosomal subunit then joins the newly formed complex. The initiator tRNA resides in one bindin ...

Molecular evolution

Molecular evolution is a change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes.
