In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear ...

Yizhi “Patrick” Cai is coordinating a global effort to write a complete synthetic yeast genome. If he succeeds, the resulting cell will be the artificial life most closely related to humans to date.

Located at the ends of eukaryotic chromosomes and synthesized by the enzyme telomerase, telomeres maintain the length of chromosomes. The majority of human cancer cells express high levels of ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

The histone proteins of complex cells are named H2A, H2B, H3 and H4. They are assembled into groups of eight, around which a ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

Exploring the evolutionary timeline, the unicellular last common ancestor shared between algae and animals did not possess the distinct sex chromosomes found in these two groups of organisms. The ...

Accordingly, defects in chromosome replication are a major driver of the genomic instability observed in cancer cells. To understand the molecular mechanisms by which eukaryotic cells carry out and ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

Klinefelter syndrome is a genetic condition in which a boy is born with an extra X chromosome. Instead of the typical XY chromosomes in men, they have XXY, so this condition is also called XXY ...

Increased risk for autism appears to be linked to the Y chromosome, a study has found, offering a new explanation for the greater prevalence of autism in males. Increased risk for autism appears ...
