Cells come in many different varieties, with many different functions, but inside, almost every cell is a nucleus, containing 99.9% of your genes, and mitochondria, containing a few more genes. All told, you’ve nearly 20,000 genes, your genes are small parts of a long molecule, called D...
Since people possess a homologous pair of each chromosome, usually one from the father and one from the mother, many genes are presented twice. Variations in the sequence of these genes are called alleles, and differing alleles may interact in a variety of ways depending on the chromosome on ...
Female Student: Right. And these transposons are, you know, like, little bits of DNA that are able to move from one cell to another.That’s why they’re called "jumping genes."They kind of, you know, “jump” from one cell to another. ...
What is the situation in which the phenotypes of both alleles are exhibited in the heterozygote because both alleles affect the phenotype in separate, distinguishable ways called? What is it called when two different genes, when paired, blend together and produce a third phenotype? (For example...
you cut the tree at a certain distance, again why and how you do that is beautifully explained on the number 2 reference I provided. After cutting the tree, you get a number of modules where the genes are highly connected and may provide biological insights. These modules are called "gene...
Your genes come from your parents,and they decide everything about you such as your hair color,your eye color,your weight,your height,and so on.Genes are still a bit of a mystery(神秘) to scientists,but they' re learning new things about them all the time. ...
By the 1940s, technology had become advanced enough that scientists were able to study the gene itself—that genes were made of DNA, and this DNA is carried in structures called chromosomes. These chromosomes then determine which traits are seen in the next generation. By 1953, a pair of sc...
Genetics (遗传学) is the science of what makes you who you are. People who study genetics, called geneticists, learn about how parents pass on information through their ‘genes’ (bits of information in your body that you cannot see) to their children. Is there anyone in the world like ...
