Answer: is accomplished by DNA polymerase.
Explanation: DNA polymerase is an enzyme that catalyzes the synthesis of a complementary strand of a DNA molecule during replication. The double stranded DNA helix is first unwind by the enzyme known as helicase giving rise to two DNA strands which serve as templates for replication. DNA polymerase then binds to a primer, a short nucleotide sequence and catalyzes the attachment of nucleotides to the primer to form a growing strand that is complementary to the parent DNA.
Answer:
B. finishing a sensation
Explanation: The closing phase of project management is the final phase of the project lifecycle. This is the stage where all deliverables are finalized and formally transferred, and all documentation is signed off, approved, and archived. All project management processes have been executed.
Huh ??? please provide more information
Mrs. F has low k+ levels because the liver destroys aldosterone. Aldosterone is a substance used to stimulate the secretion of potassium (k+) in the kidneys. Destruction of this enzyme would mean the reduction of potassium in the body. The inhibition of aldosterone occurs when renin is inhibited.
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.
