Question

Which of the following controls the expression or trait or a character? ( ) A) Gene B) Loci C) Cytoplasm D) RNA

Answer 1

(A) Gene

What is a gene?

• The unit of organic molecule that serves as bearer and carrier of hereditary characteristics is known as gene. In other words, a segment or part of a nucleic acid, responsible for carrying the information for a biological function or a phenotype and that is required for the formation of a functional polypeptide, is known as a gene.
• The genetic material or genes must store genetic information and accurately transmit that information from parents to offspring, generation after generation. This function is achieved by replication.
• Genes control the functions of DNA and RNA.

Answer 2

(A) Gene controls the expression or trait or a character

Explanation:

• Traits can be determined by genes or the environment, or by interactions between the two. Genes regulate the expression of a characteristic or a personality in an organism.
• Proteins are created by genes. The proteins function as enzymes that can either directly regulate a character or aid in the synthesis of a hormone that can govern the expression of a certain character.
• The genes regulate the trait by producing a particular protein. Genes are segments of DNA that provide information for the production of RNA, which in turn makes protein.
