_____ phase is a period in the life of the cell when it is conducting cell division. M phase
G1 phase
G2 phase
S phase

Answers

The question is asking for the term that is used to describe the phase in the life of the cell when cell division is taking place. The correct option is M phase [mitotic stage], that is, option A. In eukaryotic cells, the phases of the cell cycle are divided into two major phases, which are interphase and mitotic stage. During the mitotic stage, cell divides its DNA and cytoplasm into two equal parts, thereby forming two daughter cells.

Answer:

The correct option is M phase

Explanation:

Which of these best describes the role of helicase and DNA polymerase in DNA replication? *A. DNA polymerase "unzips" the DNA strand, while helicase brings in new strands of DNA to match the old strands

B. Helicase attaches new nitrogen bases to the ends of old DNA strands, while DNA polymerase breaks down unused DNA strands

C . DNA polymerase breaks down the old strand of DNA after a new one has been replicated, while helicase connects the two DNA strands together

D. Helicase "unzips" the DNA strand, while DNA polymerase brings in new strands of DNA to match the old strands

Answers

'Helicase "unzips" the DNA strand, while DNA polymerase brings in new strands of DNA to match the old strands.' best describes the role of helicase and DNA polymerase in DNA replication. The correct option is d.

Helicase is essential for DNA replication because it "unzips" the double-stranded DNA molecule. In order to separate the two strands and create a replication fork this process involves severing hydrogen bonds between the base pairs. On the other hand, DNA polymerase is charged with the vital task of creating new DNA strands.

It does this by incorporating complementary nucleotides into the template strands already present. This maintains genetic fidelity by ensuring that the newly formed strands mirror the original ones. The precise duplication of genetic information which is necessary for cell division and inheritance, depends on the interaction between the unwinding action of the helicase and the strand-building activity of DNA polymerase.
