Answer:
two
At the beginning of the S stage, each chromosome is composed of one coiled DNA double helix molecule, which is called a chromatid. At the end of this stage, each chromosome has two identical DNA double helix molecules, and therefore is composed of two sister chromatids.
Answer:
A. Miosis
B. DNA molecule
C. Body cells
D. phenotype
E. Recessive traits
F. genotype
G. Punnet square
H. nondisjunction
I. mitosis
J. sex cells
Explanation:
In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.

<span>During the synthesis of a protein, a shortage of one needed amino acid can stop the process.</span>
<span>If the missing amino acid is a nonessential amino acid, it can be synthesized, most often by transamination, and protein synthesis can continue.
If the missing amino acid is an essential amino acid, the body cannot make the amino acid, but it can break down some of its own proteins to obtain it. If an amino acid cannot be supplied, protein synthesis stops.</span>
