Answer:
Two
Explanation:
Consider the sequence ATGACATGCAATTGA.
Originally, there are 5 codons, translating to a minimum of 5 amino acids: ATG CAT GTC AAT TGA.
A base was inserted after the first G and the third T was deleted, the sequence become (assuming A is the inserted base);
ATG <em>ACA TGC</em> AAT TGA
<em>Only the second and the the third codon are changed and hence, their respective amino acid.</em>
According to G.D Budhiraja in his book "The Natural Way of Healthy Aging," the ultimate wonder of cells is the egg cell.
The egg cells is considered to be the ultimate wonder of cells because of its potential to form another human being. Once fertilized, the egg cell multiplies and grows, and "seems to know" just the right timing for certain processes to occur within the embryo or fetus. It seems to know when certain hormones should be produced, when it should implant in the uterus, and when the hands, legs, feet, hair, and other parts of the embryo and fetus should grow.
Answer:
Pregnancy, which is characteristically associated with changes in hormone levels in the body is a process tightly regulated by the hormon Human Chorionic Gonadotropin
Explanation:
The so-called pregnancy hormone is the Human Chorionic Gonadotropin (HCG). It only occurs during the gestation period and is responsible for regulating the entire process. Segregated by the placenta, it can be found in urine and blood.
The presence of the hormone in the urine allows to confirm the pregnancy with the test. As in pregnancy, the placenta begins to form, the cells that make it up begin to stimulate the production of HCG, which causes the hormone levels to increase very rapidly in the first trimester of pregnancy
