Question

You are a research assistant in a lab that studies nucleic acids. Your advisor gave you four tubes for analysis. Each of these tubes differs in its contents by the source of its nucleic acids: mouse cytoplasm (single-stranded RNA), yeast nuclei (double-stranded DNA), rotavirus (double-stranded RNA), and parvovirus (single-stranded DNA). The approximate nucleotide base composition of each sample is given in the table below. Which tube MOST likely contains yeast nuclei?

a) Mouse cytoplasm
b) Yeast nuclei
c) Rotavirus
d) Parvovirus

Answer 1

The tube that most likely contains yeast nuclei is the yeast nucleic tube, which contains double-stranded DNA.

Step-by-step explanation:

The tube that most likely contains yeast nuclei is the yeast nucleic tube. Yeast nuclei contain double-stranded DNA. According to the provided table, yeast has a higher proportion of nucleotides that are characteristic of DNA (adenine, thymine, cytosine, and guanine) compared to the other tubes.
