Question

chromosomes inside the nucleus that are paired with others of similar size, shape, and carrying the same genes are known as
a. homologs.
b. histones.
c. genes.
d. nucleosomes.

Explanation:

• Homologs (homologous chromosomes) are pairs of chromosomes in a nucleus that match in size, shape, and carry the same genes.
• Histones are proteins that DNA wraps around to form chromatin, not paired chromosomes.
• Genes are segments of DNA that code for traits, not the chromosome pairs themselves.
• Nucleosomes are structural units of chromatin made of DNA and histones, not paired chromosomes.

Answer:

a. homologs.
