Chromosomes to genes
WebTo prevent the loss of genes as chromosome ends wear down, the tips of eukaryotic chromosomes have specialized DNA “caps” called telomeres. Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms but is 5'-TTAGGG-3' in humans and other mammals.

WebSep 4, 2024 · The process of recombination involves the breakage and rejoining of parental chromosomes (M, F). This results in the generation of novel chromosomes (C1, C2) that share DNA from both parents. During prophase I, chromosomes condense and become visible inside the nucleus. WebJul 25, 2024 · To Gene. A gene is a stretch of DNA that contains the instructions for making or regulating a specific protein. Genes that make proteins are called protein-coding genes. In order to make a protein, a molecule closely related to DNA called ribonucleic acid (RNA) first copies the code within DNA.
WebIn a study published March 16 in the peer-reviewed journal Nature Immunology, a collaborative team of UCLA researchers have found that female mouse and human NK cells have an extra copy of an X chromosome-linked gene called UTX. UTX acts as an epigenetic regulator to boost NK cell anti-viral function, while repressing NK cell numbers.
