"ricin inhibits the functioning of ribosomes. What part of protein synthesis would be affected by ricin? What effect would this
kondor19780726 [428]

Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.  

They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.  

This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.

Which pathway is affected by an inherited mutation in the atm gene?
Katena32 [7]

The question is incomplete as it does not have the options which are:

photoreactivation

reactivation repair pathway

nucleotide excision repair pathway

UV repair pathway

p53 repair pathway

Answer:

p53 repair pathway

Explanation:

ATM gene or ataxia telangiectasia-mutated is a gene which codes for the protein kinase involved in the DNA double-stranded break.

The DNA double-stranded break is repaired easily as the protein kinase is recruited to the site of the break where it allows the DNA repair machinery to repair the DNA.

The gene also controls the cell growth therefore this gene is important to study cancer.  Since the p53 protein is a suppressor protein which if mutated is repaired by the ATM gene and if the gene becomes mutated then the p53 repair pathway is affected.

Thus, p53 repair pathway is the correct answer.

11111nata11111 [884]

Answer:

A. Parasitism, because the flee is benefitting and the mammal is harmed.

Explanation:

Parasitism is when one organism which is a parasite lives on another which is the host, and gaining benefits from it and at the same time maiming havoc to it. Parasitism is common among living organisms. Animals are most times the host to a range of parasitic organisms which include viruses, bacteria, fungi,protozoa, also flea, tick, mites etc.

Parasites like fleas, tick and leeches live on the body surface of their host, which is make them ectoparasites while those that live inside their hosts are endoparasites.
