Nearly half the DNA content of the human genome consists of repetitive sequences of DNA: transposons, retrotransposons, and endogenous retroviruses.
Decoding sequences of DNA was tedious.
These days, sequences of DNA can be ordered on the Internet for pennies.
The work went on, but decoding sequences of DNA wasn't easy.
Because the fingers recognize specific sequences of DNA, they guide the control proteins to the exact site where their target gene begins.
The activity of genes is governed by transcription factors, which bind to specific sequences of DNA units that lie close to the gene.
The transcription factors recognize short sequences of DNA, about six to eight units in length, which lie just in front of the gene to be transcribed.
Software developed in recent years transforms the text sequences of DNA into digital data that a computer can read and play.
Lynx's method for attaching the genes to beads is ingenious and complicated, but in essence involves building up 32-letter sequences of DNA on a set of beads.
The Roman empire maintained standing armies to protect its frontiers, but the Huns, the Goths and the Vandals live on in almost all of us, as telltale sequences of DNA that connect Europeans from Bucharest to Bradford, and far beyond.
The methods for obtaining the nucleotide sequences of DNA have enormously improved since the 1980s and have become largely automated.
