DNA
A) is produced during cellular respiration
B) functions mainly to transmit information from one species to another
C) cannot be changed
D) is a neurotransmitter
E) makes up the genes

التوضيح

موثّق

DNA stands for deoxyribonucleic acid. DNA is a double helix chemical protein strand composed of specific amino acids with a phosphorus backbone. DNA makes up the genes of an organism.
Hence, the correct answer is option (e).
Cellular respiration refers to the process by which a cell creates energy. DNA stores the information on how respiration transpires, but the respiration does not result in DNA. Therefore, the answer is (a) incorrect.
Information cannot transmit from species to species. Therefore, the answer is (b) incorrect.
DNA is not a neurotransmitter as neurotransmission refers to the chemicals that cross the brain membrane to signal the rest of the body. Therefore, the answer is (d) incorrect.
DNA can be changed due to transcription errors or due to mutations of other kinds. DNA can also be changed by some harmful viruses and by acidic blood. Therefore, the answer is (c) incorrect.
