Every chromosome contains a single DNA molecule that runs from end to end. A DNA molecule has two strands. Each strand is a long, linear sequence of four chemicals: adenine (A), cytosine (C ...
The Homo sapiens genome today contains a little bit of Neanderthal DNA. These genetic traces come from almost every part of the Neanderthal genome—except the Y sex chromosome, which is ...
But despite being an ideal test case to study the underlying mechanisms of the chromosome drive, B chromosome research has only slowly been able to capitalize on the data explosion of the DNA ...
The nucleus of one of your skin cells contains about two metres of DNA, so a chromosome is a very large molecule compacted into a very small space. Watch the video below to see how DNA can be ...
Researchers have uncovered a serious side effect of using the CRISPR-Cas gene scissors. A molecule designed to make the process more efficient destroys parts of the genome.
