9What role does the MutL protein play in DNA repair? (5 POINTS)
It performs a proofreading function, similar to DNA polymerase, and removes incorrect bases from the template DNA strand.
It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.
It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired.
It helps to link together regions of DNA, after an error has been removed via exonuclease.
10If a mutation occurs that affects the large subunit of a ribosome, rendering it inactive, how would this affect translation? (5 POINTS)
The small subunit of the ribosome would fail to associate with a mRNA.
Methionine tRNA would not recognize the start codon of a mRNA.
New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.
Arginine tRNA, rather than methionine tRNA, would associate with a mRNA’s stop codon.
8) The region associated with the gene is : ( A ) Silencer
9) The role played by Mutl protein in DNA repair is : ( C ) It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired.
10) The effect on translation is : ( C ) New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.
The silencer is the region of the DNA that regulates the expression of DNA in RNA and protein, since the mutation cannot regulate the expression of genes the region associated with this is the silencer.
Mutl proteins helps in identifying template DNA strand and newly synthesized DNA strand. they are also used in the treatment of methyl mismatch. also
Translation is inhibited when a large unit of ribosomes is affected by a mutation.
Hence we can conclude that The region associated with the gene is : Silencer. The role played by Mutl protein in DNA repair is :It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired.The effect on translation is New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.

Answer:
8- silencer
9- It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired
10- New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.
Explanation:
Question 8
As the question is, mutation is unable to regulate gene expression and occurs in all cells. Thus, silencer are the DNA control region and regulate the expression of DNA into RNA and protein. Hence, option a is correct.
Question 9
This protein is used to differentiate between tempelate DNA strand and newerly synthesized DNA strand to rectify the foundation incorporated during DNA replication; it helps to identify new synthesizes of DNA. MutL Proteines are a proteins used to treat a methyl mismatch repair system. Hence, option c is correct.
Question 10
If the large unit of ribosome is affected by a mutation, new amino acid is not introduced after inhibition of the original methionine and translation. Hence, option c is correct.
Answer: Sorry if I'm wrong.
Explanation: The hypothalamus is the link between the endocrine and nervous systems. The hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body. The hypothalamus plays a significant role in the endocrine system.

Answer:
D
Explanation:
The best way she can gather evidence to support a claim of the bacteria developing from the material left from the earlier experiment would be to repeat the original experiment again, leave some of the Petri-dishes uncleaned, and then see if the same bacteria would grow on the uncleaned Petri dishes.
If indeed the bacteria developed from the material left from the earlier experiment, the same bacteria should grow on the uncleaned Petri dishes in the second experiment. If they do not grow, it means that the source of the bacteria is from somewhere else within the lab.
The correct option is D.
