5. What types of genes change very slowly?

2 answers:

4 0

Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.

Type 2 causes serious medical problems beginning in infancy, while Type 3 progresses more slowly than Type 2. There are also other more unusual forms that are hard to categorize within the three Types. Gaucher disease is caused by changes (mutations) in a single gene called GBA. Mutations in the GBA gene

B.UNICEF

C.CDC

D.USMLE

OSHA is the short form for the Occupational Safety and Health Administration which is an agency of the United States Department of Labor located in Washington D.C, USA.
The agency works to set and enforce standards for safe and healthy working environment for both men and women who work in private and public sectors.
The employers of OSHA have the responsibility to provide a safe workplace and ensure that no serious health hazards take place in the same.

if a retrovirus could infect one of any of these kinds of cells, which would amplify it the most within the first 2 hours?

ryzh [129]

Cancer cells are the best target to amplify the most within first 2 hours. Highly oncogenic retroviruses are recombinants of viral and host genes.

Retroviruses are viruses with RNA rather than DNA in their genomes that infect cancer cells. Reverse transcriptase is an enzyme that is used to integrate into the DNA of the host cells. It is enhanced to a greater extent the more cell replication takes place. More retroviruses are then produced by the cell, infecting further cells. Many diseases, including AIDS and various types of cancer, are linked to retroviruses.

Low-incidence cancer-causing retroviruses lack inserted host information. Instead, it seems that they alter the expression of potentially carcinogenic host genes, which in turn results in cancer. Retroviruses incorporate proviral DNA into the chromosomal DNA of their host during the course of their regular life cycle. Integrations take place across numerous locations. Although most integrations are benign, some can cause cancer. Many of these seem to encode tyrosine phosphorylating protein kinases.
