Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

Answer:
Option (2).
Explanation:
Cell division is the process by which cell increases its number with the help proteins and enzymes. The four main phases of the cell cycle are G1 , S, G2 and M phase.
The cell cycle sequence is important for the proper division of the cell. Any change in these sequences might result in cancer and other disease. The skipping or change of any stage might cause the lack of material. The cell will lose the energy to divide or may result in uncontrolled cell division.
Thus, the correct answer is option (2).
ATP has one more phosphate group than ADP
Answer:
The correct answer is -
gly-met-arg-phe-val-pro
Explanation:
The production of the amino acid chain or sequence from the desired DNA sequence is called the protein synthesis or central dogma that involves two processes, transcription and translation. Transcription is the process of transcribing the information encoded in the DNA sequence into a complementary mRNA sequence. The translation is the second process that involves the translation from mRNA to a specific amino acid.
mRNA sequence is complementary to the DNA
so, DNA - CCC-TAC-CGC-AA-CG-CC
mRNA - GGG-AUG-CGC-UUU-GUC-GG
and amino acid from the chart : gly-met-arg-phe-val-pro
