Question

Which of the following statements is incorrect?

(a) For every hormone, there is a gene.
(b) For every protein, there is a gene.
(c) For the production of every enzyme, there is a gene.
(d) For every type of fat, there is a gene

Answer 1

The incorrect statement is (d) For every type of fat, there is a gene, because fats are not directly encoded by genes, but are synthesized through enzyme-mediated pathways influenced by various genes.

Step-by-step explanation:

The question is asking which statement is incorrect in relation to genes and the substances they code for in the body. Genes are the instructions for making proteins, which include enzymes and hormones. Hormones are signaling molecules that are often proteins themselves, and enzymes are proteins that catalyze biochemical reactions. As such, there is indeed a gene for every hormone and enzyme as they are proteins. However, fats, also known as lipids, are not encoded directly by genes, rather genes encode the enzymes that participate in the synthesis of lipids. Therefore, the correct answer is:

(d) For every type of fat, there is a gene.

is the incorrect statement. Fats are synthesized through various biochemical pathways that are not directly controlled by a single gene, but rather by multiple genes that may influence the enzymes involved in lipid metabolism.
