All of the information needed to build and maintain an organism — whether it's a human, a dog, or a bacterial cell — is contained in its DNA. DNA molecules are composed of four nucleotides ...

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

Transcription is the process by which the genetic information in DNA is copied into a complementary RNA strand. RNA polymerase enzymes read the DNA sequence and synthesize messenger RNA (mRNA) ...

And in every one of the 100 trillion cells, the sequence of these four letters ... We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein ...

Kokoris came up with the idea of solving some of the noise issue of nanopore sequencing by converting DNA into larger ...

With CRISPR-Cas9, the crRNA/tracrRNA sequence or an artificial guide RNA indicate where the DNA can be cut ... it is much easier to ‘program’ CRISPR-Cas9 at a particular cutting point on the DNA ...

A new structural blueprint paves the way for improved targeting of cancer cells, particularly those with BRCA1 and BRCA2 ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed ... RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.

on the complementary strand. Transversion mutations: A change from thymine to adenine (T → A) or guanine (T → G). Thymine deletions or insertions: The loss or gain of one or more thymine bases in the ...
