DNA contains the code for constructing the protein molecules in a cell of an organism. Thus, the correct option is A.
DNA stands for deoxyribonucleic acid. DNA is a polymer which is composed of two strands or chains of polynucleotide chains which coil around each other to form a structure called as double helix.
The nucleic acid polymer carries the genetic instructions for the development, functioning, growth and reproduction of all the known living organisms and many of the viruses. DNA and RNA are nucleic acids. DNA contains the cods for the construction of protein molecules.
Therefore, the correct option is A.

Your question is incomplete, most probably the complete question is:
DNA contains the code for constructing which molecules?
a. Proteins
b. fats
c. starch
d. sugars
Answer & Explanation:
After a complimentary DNA chain is generated as messenger RNA (mRNA), Sequence of nuclotides in a mRNA directs the addition of a specific sequence of amino acids to form the protein. This usually occur on ribosome.
The polypeptide chain now increases in length by covalent attachment of successive amino acids units, each carried to the ribosome and correctly positioned by its transfer RNA (tRNA). The completion of the polypeptide chain is signalled by a termination codon present in the mRNA.
Answer:
monosaccharide
Explanation:
took the test and passed
c. Genetic mutations
b. Enhanced physical ability
d. Damage of reproductive organs
The distance traveled by an object divided by the time it takes to travel that distance is called
a. average velocity.
c. average acceleration.
b. average speed.
d. activity.
Energy in most ecosystems must flow through autotrophs because only autotrophs can convert solar energy in chemical energy.
Explanation:
This suggests that these are organisms which are entirely based on the Greek name self-producers that can produce complex organic materials by fixing together simple building blocks in their local situation. E.g plants on land. Photosynthesis in plants transforms solar energy into chemical energy using electrons and protons from water. The method of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic aggregates and oxygen.
