The sequence of base pairs in DNA determines the genetic code, which is read in triplets (codons) to specify the amino acid sequence of proteins. The complementary nature of base pairing allows for ...

To prepare a sample, DNA is fragmented into 100–200-base-pair pieces, and then adaptors of known sequence, often poly(A) tails, are attached to the ends of DNA fragments. “We can capture that ...

But this magnifier doesn't enlarge the view of DNA bases. Rather, it makes billions of identical copies of a small sequence of DNA -- enough copies to allow a machine to detect marked bases within ...

A) DNA polymerase binds to a single-stranded DNA template (blue) and synthesizes a complementary strand of DNA (red). B) When DNA polymerase randomly incorporates a fluorescently labeled ddNTP ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...

In DNA, cytosine pairs with guanine through three hydrogen bonds, forming a stable base pair. The sequence of these base pairs along the DNA strand encodes genetic information. During DNA replication, ...

Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll ...
