How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...

The challenge is to integrate the information into a coherent picture of chromosome structure and function. Continued information-gathering will be necessary but not sufficient to achieve such a ...

DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of ...

How did humans evolve brains capable of complex language, civilization, and more? The answer could lie in exceptional DNA.

Contains genes that help cell to function, eg genes for antibiotic resistance Bacterial cell ? Compartment in cell where DNA is stored as chromosomes Controls activities of cell Animal cell ...

Transposons, or "jumping genes" - DNA segments that can move from one part of the genome to another - are key to bacterial ...

In the absence of DDM1 and RNAi, this TE doesn’t produce small RNAs, so the centromere is not methylated. These mutants also ...

Cytoplasmic flows guide chromosome positioning during embryogenesis. During the first stages of animal embryo development, the egg cell undergoes multiple divisions without growin ...

Scientists are exploring gene editing as a way to correct trisomy at the cellular level. Using CRISPR-Cas9, researchers ...
