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.

Answer:
D. Chemoautotrophs
Explanation:
Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.
Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.
Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.
Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.
Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.
Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.
Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.
Independent assortment occurs spontaneously when alleles of at least two genes are assorted independently into gametes.
Answer:
Genetic counseling
Explanation:
If an individual suspected an inherited disorder(usually dangerous) in the parents, or partner's family and wish to <u>find out or investigate the pattern of inheritance,</u> or t<u>he likelihood of manifesting this conditions later in life</u>,<u> or the chances of the partner passing this down to their offspring</u>, then the expert to visit is a genetic Counsellor, while the term to describe the genetic enquires is called genetic counseling. The Counsellor also provides the necessary emotional support that the investigator may need after the discovery.
<u>Besides the above reason, Genetic counseling is also important for</u>
1.How and when to plan a baby ,if the birth is suspetabe to a disorder
2.the type of genetic screening test to go for,
3. how to protect the child and the mother during pregnancy,incase a disorder is already present,
4. to understand family history and to secure the future of the marriage.
5. the necessary safety and curative measures to give the child after birth.
Genetic Counsellors are certified expert with additional master degree in Genetic counseling.
