How is our autosomal DNA expressed? Autosomal DNA: Autosomal DNA refers to genes located on the 22 pairs of autosomal chromosomes. Humans have a total of 23 pairs of chromosomes. The non-autosomal pair includes the sex chromosomes which can either be X-shapes of Y shaped. ...
How is DNA related to reproduction?The GenomeNote that the cell genome contains all of the cell's genetic information, in the form of DNA contained within chromosomes, which dictates cell structure and function, cell metabolism, protein synthesis, etc. In humans for example, the genome will ...
Genes (基因)are made up of DNA. Genes tell your body how to grow and work. They are passed down from parents to children. Genes control everything in your body. They control things like your eye color and height. Scientists think they might control how well you play sports. This is ca...
DNA is composed of different sequences of our genes. These sequences hold directions for making the proteins that will carry out a cell's particular function. This is how one cell might end up being important to your kidneys, while another cell makes bone. When a gene is turned off, it...
Complex organisms, like plants and animals, have 50,000 to 100,000 genes on many different chromosomes (most humans have 46 chromosomes). In the cells of these organisms, the DNA is twisted around bead-like proteins called histones. The histones are also coiled tightly to form chromosomes, wh...
Research on Selfish Genes Provides New Insight Into Meiotic Drive Systems New findings from the Stowers Institute for Medical Research uncover critical insights about how a dangerous selfish gene—considered to be a parasitic portion of DNA—functions and survives. Understanding this dynamic is a valuab...
Moshe Szyf is a pioneer in the field of epigenetics, the study of how living things reprogram their genome in response to social factors like stress and lack of food. His research suggests that biochemical signals passed from mothers to offspring tell th
To turn genes in DNA "on" and "off," enzymes in cells must interact with nucleosomes, which are complexes containing proteins that allow cells to organize their DNA. One such enzyme, Dot1L, is mutated in mixed lineage leukemia, a form of childhood leukemia. ...
1、DNA is the whole "map" of the human body.It is something that all humans have,and it tells the body what to do.DNA is the reason that we look like our parents,because we get some of their DNA to make our own.People have been trying to understand the human body for a long ...
