Ответ:
In the diagram, both structure B and C are fragments of DNA, which are found within structure A -which is a chromosome- so the statement that best describes the relationship is structures B and C are located within Structure A and code for inherited traits (option a).
Explanation:
Chromosomes are structures, present in cells during cell division, each consisting of one DNA molecule. Each fragment of the DNA molecule within a chromosome represents a gene, which contains the information needed to determine a trait in an individual.
According to the diagram (image), the DNA fragments B and C are genes that are found within structure A, the chromosome, and determine inheritable traits.
