Meiosis produces 4 haploid daughter cells and is essential for forming gametes that contain one copy of each chromosome. Meiosis allows genetic diversity which gives rise to new combinations of genetic allel...

When moving across a selectively permeable membrane, ions, polar and large molecules cannot dissolve easily in the lipid membrabe. Instead, transport must occor by way of protiens that act as carriers or cha...

Gamete production is controlled by hormones in humans. The hypothalamus produces Gonadotrophin-releasing hormone (GnRH) which in turn stimulates the anterior pituitary gland to produce leutinizing hormone (L...

DNA is a nucleic store of genetic information in eukaryotes. It consists of a combination of four different nucleobases; adenine, cytosine, guanine and thymine (abbreviated to A, C, G and T respectively). So...

Scientists in labs use a technique called gel electrophoresis which allows them to separate a mix of DNA fragments by size . This is used in conjunction with PCR (polymerase chain reaction) and restriction d...
