By referring to the observation that DNA is found exclusively in the nucleus while proteins are found throughout the cell, the scientist supporting the DNA Hypothesis implies that genes are made only of DNA because which of the following are also found only in the nucleus?(1 point)

Question

Responses

Proteins
Proteins

Chromosomes
Chromosomes

Gametes
Gametes

Amino Acids

Answer 1

The correct response is Chromosomes.

The scientist supporting the DNA Hypothesis implies that genes are made only of DNA because chromosomes, which are structures that contain DNA, are found exclusively in the nucleus. Proteins, gametes, and amino acids can be found throughout the cell and are not limited to the nucleus.

Answer 2

According to the Protein Hypothesis, which of the following observations provides the strongest evidence that genes are NOT composed of DNA ?(1 point)
Responses

DNA is composed of only 4 types of nucleotides.
DNA is composed of only 4 types of nucleotides.

The concentration of DNA is generally consistent from cell to cell.
The concentration of DNA is generally consistent from cell to cell.

DNA is abundant in both the nucleus and the cytoplasm.
DNA is abundant in both the nucleus and the cytoplasm.

DNA is composed of smaller subunits than are proteins.

Answer 3

The strongest evidence that genes are NOT composed of DNA, according to the Protein Hypothesis, is:

DNA is abundant in both the nucleus and the cytoplasm.

This observation suggests that if DNA were to serve as the genetic material (as proposed in the DNA Hypothesis), it should remain primarily in the nucleus to perform its role in heredity. However, its presence in the cytoplasm might imply that its role is not exclusively genetic, supporting the idea that proteins might play a more critical role as the primary constituents of genes.
