Answer:
Biological markers
Homeostasis
House keeping
Explanation:
Autoantibodies are also reffered to as natural antibodies. This antibody react with self molecules in the body system to fight against infection.
This antibodies are produced by genes that are not mutated.
They provide the immediate defence against disease or infection and help in keeping the body fit.
They are useful in the regulation of body function or activities i.e homeostasis
Autoantibodies are useful as biological marker in targeting some disease that are present in the body as they could be specific to certain organs in the body.

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.
When a cell with 18 chromosomes divides by meiosis, the result would be four daughter cells, each with 9 chromosomes, option(c). This is because meiosis reduces the number of chromosomes in each daughter cell by half.
The best description of the expected daughtercells when a cell with 18 chromosomes divides by meiosis is: The result would be four daughter cells, each with 9 chromosomes. This is because meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell. The process of meiosis begins with a parent cell that is diploid, meaning it has two complete sets of chromosomes. During meiosis, this cell undergoes two rounds of division, resulting in four haploid daughter cells, with each containing half the number of chromosomes as the original parent cell. In this case, the original cell has 18 chromosomes, so each of the four daughter cells will end up with 9 chromosomes, option(c).

a. The result would be two daughter cells, each with 18 chromosomes.
b. The result would be four daughter cells, each with 18 chromosomes.
c. The result would be four daughter cells, each with 9 chromosomes
d. The result would be two daughter cells, each with 9 chromosomes.

Explanation:
The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum.
