Answer:
A. Prepares for cell division
Explanation:
The S phase is when the DNA divides, so B is incorrect.
The post mitotic phase (G0 phase) happens before the cell divides, so C is incorrect.
Answer:
According to the number of sequence on DNA there should be 10 amino acid. But after 7 amino acid there is stop codon so only 7 amino acid can be synthesized.
Explanation:
DNA sequence given here is CCTACCTTATGCCAAGTTGGGGATAAACTC it is read from left to right. When this DNA is transcribed mRNA sequence will be-
GGAUGGAAUACGGUUCAACCCCUAUUUGAG. These 30 nucleotide will synthesize following amino acids-
GAG UUU AUC CCC AAC UUG GCA UAA GGU AGG-
Glutamine, Phenylalanine, Isoleusine, Proline, Asparagine , Leucine, Alanine, stop codon. As ribosome reach on stop codon protein synthesis stopped and process aborted.

5. The phenotypic ratio is 9:3:3:1 where 9 combinations will produce offspring with both dominant phenotypes (dimples and brown hair), 3 will produce offspring with one dominant phenotype and one receive phenotype (dimples, blonde hair), 3 will produce offspring with one receive phenotype and one dominant phenotype (no dimples, brown hair), and one will produce offspring with both recessive phenotypes (no dimples, blonde hair)
