A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.

Answers

Answer: the answer is A

Explanation:

Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.

On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.

I guess the answer would be because of meiosis in meiosis this is because in prophase the two chromosomes cross over and the genes are mixed leading a random mix of characteristics. Mutations can also cause these differences so the offspring are different and not the exact copy as parents.

Which statements correctly describe mutations in gametes and mutations in somatic cells?
Mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Mutations to gametes are more likely to be beneficial than mutations to somatic cells.
Mutations to somatic cells will be inherited by an organism's offspring.
Mutations to gametes can be passed on to an organism's offspring
O Mutations to gametes do not involve changes in the DNA.
Mutations to somatic cells are transferred to daughter cells.

Answers

Answer:mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.

Explanation:The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.  

On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.  

Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.  

Hence, the correct statements are

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.

Answers

Answer:

prokaryotes

Explanation:

All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.

What is translation in prokaryotes?

In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.

This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.
