In eukaryotes, DNA is housed within the nucleus, but in prokaryotes ... pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

Human immunodeficiency virus type 1 (HIV-1) targets important cells of our immune system, making infected individuals more ...

A large structure called the mitotic ... or pole, of the cell. During prometaphase, the nuclear envelope that encloses the nucleus breaks down, and the nucleus is no longer separated from the ...

Within every cell (except red blood cells) is a nucleus -- a sphere-like structure separated from the rest of the cell by a membrane. The nucleus acts as the cell's control center, regulating its ...

Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists ...

Once inside human cells, HIV integrates the viral genome into that of ... similar to a nail that breaks its surrounding structure once driven forward. This crack widens the channel and allows the ...

can also be located in the cell nucleus, where the genetic material resides. Remarkably, nuclear Talin-1 was shown to influence the expression of genes that regulate cell-to-cell connections.

Plant cells have a rigid cell structure. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus, and chloroplasts. Plants feel firm because of their cellular walls.

To pull this off, HIV needs to sneak its genetic blueprint into the cell nucleus. The nucleus ... cleverly mimics the structure of these transporters. It has evolved into a transporter with ...
