Answer:
d. NRC
Explanation:
DNA or deoxyribonucleic acid is the genetic material we get in all living things, from bacteria to mammals.
DNA is found in the nucleus of eukaryotic organisms and in chloroplasts and mitochondria. In prokaryotes, DNA is free floating in the cell.
RNA (Ribonucleic Acid) is one of the basic nucleic acids for life, in charge of DNA synthesis (protein deoxyribonucleic acid) in the work of protein synthesis and genetic inheritance.
This acid is present inside both prokaryotic and eukaryotic cells, and even as the only genetic material of certain types of viruses (RNA Virus), and consists of a single chain molecule of nucleotides (ribonucleotides) formed in turn for a sugar (ribose), a phosphate and one of the four nitrogenous bases that make up the genetic code: adenine, guanine, cytosine or uracil.
Central nervous system (CNS) is made up of the brain and spinal cord. They are protected by three membranes: dura (external membrane), arachnoid (intermediate membrane), pia mater (internal membrane) generically referred to as meninges.
