Which of the following best describes the way that genes, chromosomes, and DNA are related? A. Genes contain several sequences o
f DNA, which are made up of chromosomes. B. Sequences of DNA contain several genes, which are made up of chromosomes. C. Chromosomes contain several genes, which are made up of sequences of DNA. D. Genes contain several chromosomes, which are made up of sequences of DNA.
C. Chromosomes contain several genes, which are made up of sequences of DNA
Explanation:
Genes and chromosomes are two essential terms for understanding genetics. Genes are portions of DNA, while chromosomes are condensed DNA molecules.
Genes are portions of DNA that present the information necessary for the synthesis of a messenger RNA molecule and consequently a protein.
Chromosomes can be defined as highly condensed DNA. In the human species we have 46 chromosomes in the nucleus of our cells. These chromosomes are arranged in pairs, that is, we have 23 pairs of chromosomes. The chromosomes of a given pair are called homologues.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.
The answer would be D. Huntington's disease presents symptoms in humans after many have already reproduced; therefore, they are unaware that they passed on Huntington's disease.
