Pyruvate is coverted into the Acetyl-CoA, Acetyl-CoA contain the acetyl group which are comes from the pyruvate and Coenzyme A (CoA) that contain other groups such as;

a) A reactive thiol (—SH) group that is critical to the role of CoA as an acyl carrier in a number of metabolic reactions

b) contain pantothenic acid,  A hydroxyl group of pantothenic acid is joined to a modified ADP moiety by a phosphate ester bond

c) pantothenic acid carboxyl group is attached to β-mercaptoethylamine in amide linkage

d) Hydroxyl group at the 3’ position of the ADP moiety has a phosphoryl group not present in free ADP

which of the following correct observation about Coenzyme A (CoA)?

A panel of cell lines was created by human—mouse somatic-cell hybridization. Each cell line was examined for the presence of human chromosomes and for the production of three enzymes. The following results were obtained: 

On the basis of these results, give the chromosomal locations of the genes encoding enzyme 1, enzyme 2, and enzyme 3.

In Neurospora a cross between the genotypes 'A' and 'a' results in an ascus with ascospores of genotypes as shown below: 

 Statements A to D are events that could have occurred during meiosis.

A) Class I is results of no crossing over between the centromere and gene.

B) Class II is results of single crossing over between the centromere and gene

C) Class I shows segregation of alleles 'A' and 'a' in meiosis II

D) Class II shows segregation of alleles 'A' and 'a' in meiosis II

A three point test cross was carried out in Drosophila melanogaster involving three adjacent genes A, B and C. arranged in the same order. The distance between A to B is 15 map unit (mu) and that between B to C is 30 map. The coefficient of coincidence = 0.67. What is the percentage of double recombinants in the progeny obtained from the testcross?

When two independent pure lines AAbb and aaBB of pea with white flowers are crossed, the F1 progeny has purple flowers. Gene A and B link at 20 map unit. The following conclusions were made

A. When an heterozygous individual of the genotype AaBb is test crossed, progenies with purple and white in a ratio of 1:3

B. When an heterozygous individual of the genotype AaBb is test crossed, progenies with purple and white in a ratio of 1:9

C. This is an example of complementary gene action

D. The F2 progeny obtained on selfing shows both pruple and white flower in a ratio of 9:7                                            

Which of the following conclusions are correct?
