One hypothesis is that the DNA loops could determine which genes are switched on in the cell. Inside a nucleus, chromosomes jumble together like a game of Twister. This can bring regulatory elements, ...

Nucleus is possible because the cost of genome ... meditate for an hour, scribble gene-related company plans in a notebook for twelve hours, meditate for another hour. “I do believe in the ...

Transposons, also known as jumping genes or mobile genetic elements as they can replicate and reinsert themselves in the ...

Genes encode proteins and proteins dictate cell ... and the presence of a nucleus makes this possible. In prokaryotes, translation of a transcript begins before the transcript is complete, due ...

Gene regulation underpins nearly every biological process—from cell development to responses to environmental changes, and understanding it can provide insights into cancer and other diseases. Now, ...

A single gene can range in length from as few as 100 DNA bases to as many as several million. There's a lot of DNA within the nucleus -- about six feet if you could unravel it and stretch it out ...

Single-cell multiomic analyses reveal known and new genes and pathways involved in the development of germ cells and provide a discovery platform for the scientific community.

Researchers at Fred Hutch Cancer Center have discovered an overlooked mechanism driving aggressive breast and brain tumors ...

Humans have between 20 000 and 25 000 genes. One copy of all your chromosomes is called your genome. When an egg is fertilised by a sperm, it becomes a cell with a nucleus containing 23 pairs of ...

This study utilized high-throughput Affymetrix microarrays to identify gene expression changes in the post-mortem nucleus accumbens of chronic heroin abusers. These data were analyzed ...
