Which of the following correctly describes the shapes of the major and minor grooves in double-helical RNA? The major groove is narrow and deep - The major groove is narrow and deep and the minor groove is wide and shallow. The underlying principle of "classical" methods of DNA sequencing is to separate, by size, nested sets of DNA molecules. There are two main steps involved: (1) running a PCR-like sequencing reaction and then (2) running the extension products through a gel matrix to s...

Here we report the whole-genome sequencing and assembly of the genome of the marmoset, the first New World monkey to be sequenced (Supplementary Note). Our results include comparisons of this platyrrhine genome with the available catarrhine (human, other hominoid and Old World monkey) genomes, identifying previously undetected aspects of catarrhine genome evolution, including positive selection in specific genes and significant conservation of previously unidentified segments of noncoding ...
