Answer:

D. Cytoskeleton

Explanation:

It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.

The Cell Walls are only in plant cells so that won't work. So, A wouldn't work.

Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.

Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either

The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.

Identify the stages of mitosis .

Alexxandr [17]

Mitosis has five different stages: interphase, prophase, metaphase, anaphase and telophase. The process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase. Each stage of mitosis is necessary for cell replication and division.

Rb is an important protein for controlling cell proliferation by blocking entry into S phase. How does it exert its effect?

amid [387]

Answer:

The main function of the RB protein is to inhibit the transition from the G1 to S phase. Its activity depends on its phosphorylation state: if RB is not phosphorylated (active state), it is bound to the transcription factor E2F, preventing its translocation to the nucleus and the activation of genes necessary for DNA synthesis; and if it is phosphorylated, by cyclin-CDK complexes, E2F is released and cell proliferation occurs.

Explanation:

Retinoblastoma (Rb) was the first tumor suppressor described and, as we know today, mutations in its structure determine a large number of cancers. Structurally, we speak of a large and multifunctional protein; which is organized in different domains. The activity of this protein is regulated, mainly, by phosphorylation at multiple sites described over the years and is involved in control mechanisms of the cell cycle, apoptosis and senescence.
