Answer:
d Meth-Arg-Asn-Pro-Leu-stop
Explanation:
This question is describing the processes of transcription and translation of protein synthesis. Transcription is the synthesis of mRNA from DNA while translation is the synthesis of amino acid from mRNA. In this question, the following DNA sequence is given:
TAC/GCA/TTA/GGC/AAC/ACT
- Following the complementary base pairing rule i.e A-U, G-C, T-A etc, the following mRNA transcript will be produced after transcription:
AUG/CGU/AAU/CCG/UUG/UGA
- Using the genetic code, the following amino acid sequence will be produced from the above mRNA sequence after translation:
Methionine/Arginine/Asparagine/Proline/Leucine/STOP.
Answer: Option C) It is a frameshift mutation that changes many amino acids.
Explanation:
Due to the triplet nature of gene expression by codons, the insertion of the single Adenine nucleotide will disrupt the reading frame of the gene (frameshift mutation), such that it is no longer evenly divisible by three.
Thus, resulting in a completely different translated protein from the original.
Answer:
All enzymes have an ideal pH value, which is called optimal pH. Under the optimum pH conditions, each enzyme showed the maximum activity. For example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. All enzymes have an optimum pH that they work best at. Its often neutral pH 7, but not always.

Histones package and order DNA into the structural organized units called nucleosomes. They play a large role in gene regulation.
