Answer (1)

Answer:DNA is the blueprint of life.DNA's structure is like a twisted ladder. The sides are made of sugar and phosphate. The rungs are pairs of bases: Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G).DNA holds the instructions to build and control an organism's traits. Different DNA sequences tell the body to make different proteins, which determine these traits.A chromosome is a tightly coiled structure of DNA. Humans have 46 chromosomes per cell, arranged in 23 pairs.A gene is a small section of DNA that carries the instructions for a specific trait or function.Chromosomes are made of long strands of DNA. Genes are segments of this DNA. Many genes are located on each chromosome.
