How does dna in cells determine an organism's complex traits?
a.) dna contains codes for proteins, which are necessary for the growth and functioning of an organism.
b.) dna separates into long single strands that make up each part of an organism.
c.) dna produces the energy an organism needs in order to grow.
d.) dna folds into the nucleus of each of the cells of an organism.

The correct answer is A) DNA contains codes for proteins, which are necessary for the growth and functioning of an organism.

DNA ( deoxyribonucleic acid) is the genetic material of all living organisms. It is called the blueprint of life as it contains the information required for the growth, survival, development, and reproduction of an organism.

The information from DNA ( in the form of nucleotide sequences) is first copied to mRNA ( messenger RNA), which is finally used in the synthesis of proteins. The proteins are necessary for the growth and functioning of an organism.

Thus, option A) is the right answer.
