Answer:
A critical function of proteins is their activity as enzymes, which are needed to catalyze almost all biological reactions.
The correct answer for this question would be option D. Since the Gulf Stream is a warm water current that flows away from the equator to northern Europe, the cause for this would be most likely the <span>warm climates in northern Europe. Hope this answers the question. Have a great day!</span>
It is true that telomerase activity declines with old age which explains why cells lose their ability to divide after many replications.
Telomeres are DNA–protein complexes found at the ends of each chromosome they contain repetitive sequences of DNA. Telomeres protect the genome from nucleic bases degradation, unnecessary recombination, repair, and prevent the fusion of chromosomes. Telomeres, therefore, play a vital role in preserving the information in our genome.
Telomeres shorten with every consecutive DNA replication cycle limiting the number of cell divisions a cell can undergo, Telomeres act as a tumor suppressor by halting the replication of cells which contains several mutations after many division cycles.
