Ever since recombinant DNA has been used to develop and manufacture vaccines, antivaxxers have portrayed it as evil. This ...

Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one ...

The biological sex of a human being is determined by which chromosomes make up that baby's genetic material. Females usually have two X chromosomes, while males tend to have one X and one Y ...

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.

Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant ...

A technology that uses enzymes to cut and paste together DNA sequences of interest. The recombined DNA sequences can be placed into vectors that carry the DNA into a host cell. In this host cell ...

In the 1980s, scientists knew little about the X and Y chromosomes. What they did understand was that every cell in the body contains 23 pairs of chromosomes. Each of these pairs is similar ...

A type of DNA sequence that is composed of sequences from two or more different sources or organisms, such as human and pig sources, or synthetic (lab-made) sequences and microorganisms.

if an individual is revealed to have XY chromosomes, they would fall under the male gender. However, there are exceptions, as ...

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

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 ...
