Sometimes, these footprints alter gene expression (i.e., expression of the gene in which they have been left behind) even after their related TE has moved to another location on the genome.

Genome size is the total number of base pairs in an organism. While the number of genes in an organism's DNA (red bars) varies from species to species (numbers at right), it is not always ...

Here’s how it works. CRISPR, short for CRISPR-Cas9, is a genome-editing tool that allows scientists to precisely cut and modify DNA sequences. It has revolutionized the study of genes ...

Patrick Hsu at the Arc Institute in California calls the new genome editor the “bridge editing” system because it physically links, or bridges, two pieces of DNA. It can be used to alter huge ...

That’s a strong claim, but one that other experts agree with. Yen-Ho Chen, a plant genome engineer working in industry, says, “It reminds me of when CRISPR was discovered. It’s novel ...

The researchers examined genome data obtained from the remains of 14 Wrangel mammoths and seven mammoths from a Siberian mainland population ancestral to the island dwellers, dating to up to ...

"Bridge recombination can universally modify genetic material through sequence-specific insertion, excision, inversion, and more, enabling a word processor for the living genome beyond CRISPR." ...

Genome and mutations DNA replication is carefully controlled to preserve the genetic information. However, changes in the genome do sometimes occur. These changes are known as mutations.

Barbara McClintock, Nobel laureate (1983) “Everything in the last 14 years of genome editing has been based on CRISPR. We have been whipping this horse for a decade and a half, but we need more ...

Except for identical twins, each person's DNA is unique. This is why people can be identified using DNA fingerprinting. DNA can be cut up and separated, which can form a 'bar code' that is ...
