The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn.
<u>Explanation </u>
The method is by adding various small DNA chains such as TTAGGG, that develop a hairpin turn. Telomerase is an RNA dependent DNA polymerase means an enzyme that can make DNA using RNA as a template. The ends of linear chromosomes called telomeres that protect genes from getting deleted as cells continue to divide. The telomerase enzyme attaches to the end of chromosome complementary bases to RNA template are added on 3 ends of the DNA strand.
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains.
The correct answer is - No.
The Cambrian explosion is a term used for the big and rapid diversification of the animal species, but it is not the period in which the animal life started. The animal life started in the period between 620 and 550 million years ago, in what is known as the Vendian Period. In the Vendian Period, the first complex animal organisms appeared, started to develop and evolve, though it is not a period where there was a high diversification of the species. The later Cambrian Period provided better living conditions, and that resulted in a so called ''explosion of life'', which resulted in much more new species developing and evolving.
