store and transmit genetic information
|
Detailed explanation-1: -All of these are functions of proteins except (d) storing genetic information of living things, which is the role of deoxyribonucleic acid (DNA).
Detailed explanation-2: -The correct answer is (E) Transmit hereditary information. Proteins have many different roles in living organisms. Some proteins provide structural support to cells. Others are peptide hormones, carrying signals throughout the body.
Detailed explanation-3: -Proteins help fight disease, control the rate of reaction and move substances into or out of cells. However, proteins do not store and transmit genetic information and thus the correct answer is A.
Detailed explanation-4: -Answer and Explanation: No, proteins do not store genetic information or transmit to the next generation. The genetic information is stored in the form of nucleic acids i.e. deoxyribonucleic acids (DNA) or ribonucleic acids (RNA).
Detailed explanation-5: -They also assist with the formation of new molecules by reading the genetic information stored in DNA. Messenger proteins, such as some types of hormones, transmit signals to coordinate biological processes between different cells, tissues, and organs. These proteins provide structure and support for cells.
