Question

how does dna in cells determine an organisms complex traits? dna folds into the nucleus of each of the cells organism dna separates into long single strands that make up each part of an organism dna produces the energy an organism needs to grow dna contains codes for proteins, which are necessary for the growth and functioning of an organism

Explanation:

DNA has genetic information that codes for proteins. Proteins are crucial for an organism's growth, development, and functioning, thus determining complex traits. DNA does not fold into the nucleus (it's in the nucleus), doesn't separate into long single - strands to make up body parts, and doesn't produce energy for growth.

Answer:

DNA contains codes for proteins, which are necessary for the growth and functioning of an organism
