Correct answer: Option D- DNA ligase

Explanation: In option A, thymine is a nucleotide, so it is present throughout the replication process, wherever it is required. It is added to the newly formed DNA. In option B, Helicase enzyme is active during initiation and elongation stage, as it facilitates the opening of the winded DNA strands. Option C is nucleotidase and it has no role in DNA replication. So, the correct answer is DNA ligase, which is option D.

The okazaki fragments formed during DNA replication are sealed at the end. And in this step, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of okazaki fragments. So it is the last active molecule of the process.

The information from messenger RNA is used to create polypeptide sequences during the process of _____.​
polet [3.4K]

Answer:

Translation

Explanation:

The translation is the process during which the nucleotide sequence of the mRNA is read in the form of genetic codes. The nucleotide sequence of mRNA is complementary to the template DNA strand. According to the sequence of the nucleotides in the mRNA, the amino acids are added in a specific order to make the polypeptide chains. The process occurs on ribosomes. The ribosomes move along the mRNA to read its sequence and the tRNA brings are amino acids to be added to the polypeptide chains.
