____ are nucleic acid functions
A
store & transfer genetic info
B
store & create energy
C
structure & energy for cells
D
membrane structure and nutrient transfer
Explanation: 

Detailed explanation-1: -Definition. Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.

Detailed explanation-2: -The natural nucleic acids DNA and RNA serve as the repositories and carriers of genetic information for all life on earth.

Detailed explanation-3: -Eukaryotic organisms (animals, plants, fungi, and protists) store most of their DNA inside the cell nucleus and some of their DNA in organelles, such as mitochondria or chloroplasts. In contrast, prokaryotes (bacteria and archaea) store their DNA only in the cytoplasm.

Detailed explanation-4: -Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

Detailed explanation-5: -Nucleic acids are polymers that store, transmit, and express hereditary (genetic) information. This information is encoded in the sequences of monomers that make up nucleic acids. There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores and transmits genetic information.
