Oksana_A [137]

Complete Question:

A) Animal

B) Fungi

C) Plant

D) Protist

<u>Correct Option:</u>

<u>Animal</u> Kingdom of living things consists entirely of multi-celled, heterotrophic organisms.

Option: A

<u>Explanation:</u>

The system of scientific classification in biological science is categorized into seven main groups: kingdom > phylum > class > order > family > genus > species. Here the kingdom is the largest group while smallest is the species. The term phylum is being used in the Kingdom of Animals, and is the second largest group.

The Kingdom of Animals is made up of multi-cellular, heterotrophic species which feed on other entities to survive. Some of the animal properties in this kingdom are able to establish, function independently, and reproduce during their existence.

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.
