Detailed explanation-1: -Telomeres are distinctive structures found at the ends of our chromosomes. They consist of the same short DNA sequence repeated over and over again.
Detailed explanation-2: -The correct answer: Translation is the process of converting the language of nucleic acids (nucleotides) to the language of proteins (amino acids). The translation is the process in which the protein strand is produced from the mRNA molecule.
Detailed explanation-3: -The sequence of nucleotides in the mRNA molecule is read consecutively in groups of three. RNA is a linear polymer of four different nucleotides, so there are 4 × 4 × 4 = 64 possible combinations of three nucleotides: the triplets AAA, AUA, AUG, and so on.
Detailed explanation-4: -Because DNA polymerase can only synthesize DNA in a 5′ to 3′ direction, the other new strand is put together in short pieces called Okazaki fragments. The Okazaki fragments each require a primer made of RNA to start the synthesis.
