EXPLANATION
GS10. Which of the following is responsible for carrying genetic information in living organisms?
a) RNA
b) DNA
c) ATP
d) Enzymes
ANSWER: b) DNA
EXPLANATION:
The answer is b) DNA.
DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for living organisms. It is found in the nucleus of cells, and it is responsible for storing and transmitting genetic information from parents to offspring. DNA is made up of two long strands of nucleotides, which are linked together by hydrogen bonds. The sequence of nucleotides in DNA determines the genetic makeup of an organism.
RNA (ribonucleic acid) is also a nucleic acid, but it is not responsible for carrying genetic information. RNA is involved in the process of protein synthesis, which is the process by which DNA is used to make proteins. RNA carries the instructions from DNA to the ribosomes, which are the cellular structures that make proteins.
ATP (adenosine triphosphate) is a molecule that stores energy in cells. It is used to power many cellular processes, including muscle contraction, cell division, and nutrient transport.
Enzymes are proteins that catalyze chemical reactions in cells. They are essential for many biological processes, such as digestion, respiration, and DNA replication.
Therefore, DNA is the molecule that is responsible for carrying genetic information in living organisms.
