Citric acid cycle or tricarboxylic acid (TCA) cycle is the part of cellular respiration. This cycle is carried out in the mitochondria matrix. Citric acid cycle begins with the entry of 2 carbon compound acetyl Coenzyme A (CoA). In one turn of the cycle, one molecule of acetyl CoA enters into the cycle. On completion of one turn of  citric acid cycle, two molecules of carbon dioxide, 3 molecules of reduced NADH and one molecule of reduced FADH₂ and 1 molecule of GTP are produced.

Which of the following is homozygous dominant? a AA b Aa c aa
GarryVolchara [31]

Answer: a). AA

Explanation: Every trait is controlled by at least a pair of gene. Genes have different forms known as alleles. Alleles can be dominant or recessive. A dominant allele expresses itself in the presence of a recessive allele and masks the effect of a recessive allele. A recessive allele cannot express itself in the presence of a dominant allele and it's effect is masked by a dominant allele. Dominant alleles are usually written in upper cases such as A, T, while recessive alleles are usually written in lower cases such as a, t. The two alleles that determines a trait is called a genotype. A genotype can be homozygous if the two alleles are identical such as in AA or aa

and can be heterozygous if the two alleles are not identical such as in Aa, Tt.
