The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a "double helix," in the journal Nature.
B: Use oxygen to make ATP
It's a process in the mitochondria known as "oxidative phosphorylation" or "aerobic respiration."
**Note: "aerobic" and "oxidative" mean "uses oxygen."
Answer:
This disorder is caused by mutations in either of two different genes; one of these genes is linked to the DNA marker locus and the other gene is not.
Explanation:
A gene marker (also known as a molecular marker) is defined as a particular DNA sequence that has a specific physical location on a given chromosome. The gene markers are always physically linked with genes of interest, thereby they are useful for identifying patients affected by a given disease and/or a particular phenotypic trait. In this case, in the first study, genetic variation of the marker has been shown to be useful to map one <em>locus</em> that is associated with the disease phenotype. However, in the second study, a second <em>locus</em> that is not linked to the marker can segregate independently, thereby showing different results from the first study (in this case, it is imperative to develop a new genetic linkage analysis to discover genetic markers linked to the second gene, which is also responsible for the disease phenotype).
Answer:
Females can get an X-linked recessive disorder, but this is very rare. An abnormal gene on the X chromosome from each parent would be required, since a female has two X chromosomes. ... In each pregnancy, if the mother is a carrier and the father has the disease, the expected outcomes are: 25% chance of a healthy boy.
