Help with some questions for Microbiology
1.What approaches do organisms use for viral suppression?Explain/compare/contrast use of antibodies, RNAi, and CRISPR-CAS.
2. How might extra copies of a single viral subunit affect viral replication?
3.What are spontaneous causes of mutation? How do those happen?
4. How/why do chemicals, radiation and mobile DNA act as mutagens?
5. What is a frame-shift? What are the causes and effects of a frame-shift?
What is a frame-shift? What are the causes and effects of a frame-shift?
Ans.2. Extra copies of viral single subunit interfere the viral replication because they affect the host machinary so metavolism affect and no nourishment obtain from them so viral replication stops.
Ans.3.cause of spontaneous mutation is the exposure to the U.V rays,cycytosine to uracil deamination in the dna helix, chemical mutagens of benzene derivatives.
These affects the deletion,inversion or many things by which product changes which cause mutation.
Ans.4.chemicals,radiation affects DNA in that way to delete the gene,one nucleotide which will cause changes in the whole polypeptide production by the gene on the DNA .or it may be stop when changes in the base of the gene cause presence of the stop codon in the triplet nature of dna.
Ans.5.whole changes in the frame of the dna when addition or deletion of the base in the soecific frame of the dna because it causes whole way to read the triplet nature of the codon system by which may be the changes in the polypeptide production,same ormay bh non sense i.e polypeptide not formed due to stop codon.
Causes of frame shift is the effection by the uv rays,chemicaks,or any other mutagens which affect continuously to the body.

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
