Question

Which of the following statements BEST describes chromosomes?

a. Humans have 460 chromosomes in every cell.
b. Chromosomes are arranged in 230 pairs.
c. Chromosomes carry the codes for hereditary traits.
d. Chromosomes are found outside the nucleus of each human cell.

Answer 1

The correct answer is option c.

Step-by-step explanation:

Chromosomes refer to the compositions found within the nucleus of the cell that comprises genes of an individual. The genes refer to the DNA segments, which comprises the code for a particular protein, which functions in one or more kinds of cells in the body.

A chromosome comprises thousands of genes, and each of the normal human cell comprises 23 pairs of chromosomes, thus, a sum of 46 chromosomes. More than one gene present within a chromosome determines a trait known as a gene-determined characteristic. This trait or characteristic passes from one offspring to another. Thus, it can be said that the chromosomes carry the codes for hereditary traits.

Answer 2

The answer is c. Chromosomes carry the codes for hereditary traits. Chromosomes are thread-like structures made of proteins and DNA. Codes for hereditary traits are present in a molecule of DNA. Chromosomes can be found in the nucleus of each cell. Humans have 46 chromosomes in each cell (not 460) arranged in 23 pairs (not 230). Hope this helps. Let me know if you need additional help!
