(a) In human populations where HIV infection is common, are the frequencies of these "resistance genes" increasing, decreasing,
Misha Larkins [42]

Answer:

Increasing

Explanation:

This particular question or problem can be likened to a deductive reasoning. The viral disease known as HIV stand for Human Immunodeficiency Virus which is a disease that damages the immune system of anyone affected with the disease. The Human Immunodeficiency Virus goes through four main stages or steps that is to say the infection stage/step, the stages in which the symptoms does not show, the stages at which the symptoms start to show and the stage at which the Human Immunodeficiency Virus goes or turns to AIDS.

The frequencies of these "resistance genes" In human populations where HIV infection is common will increase. When Human Immunodeficiency Virus infection is common, people in  that particular society will develop more resistance to the virus and the survival of the fittest is taken into account as people with more resistance tends to be more healthier than the ones with less resistance.

List and describe the role of the 3 types of rna.
steposvetlana [31]

<span>There are three RNAs with a role in the synthesis of protein.</span>

mRNA, or messenger RNA, is the link between a gene and a protein. The main role of this ribonucleic acid is in transcription (”reading“) of DNA. The DNA is transcribed by RNA polymerase, and the resulting product of this process is mRNA. This form of RNA can be modified post-transcriptionally with methylguanosine caps and polyadenosine tails. RNA carries the genetic information which is copied from DNA and the information has a form of three-base code (“words”), codons. Each of these codons specifies a particular amino acid.

tRNA or transfer RNA is the molecule with the main function in translation by "decoding" the mRNA message during this process. Each type of amino acid has its own type of tRNA and also has a three-base sequence (anticodon) that can bind complementary with the codons in the mRNA.

rRNA or ribosomal RNA is a main component of ribosomes. rRNA associates with a set of proteins to form ribosomes which catalyze the assembly of amino acids into polypeptide chains (protein).

 

<span>There are also a few more types of RNA which have a regulatory function like, microRNA or siRNA.</span>
