Question

Indicate if each of the bases in problem 17.91 is found in DNA only, RNA only, or both DNA and RNA. (17.1)

Short answer

The answer to these questions is:

a) It contains both DNA and RNA.

b) It contains DNA and RNA.

c) It contains RNA.

d) It contains DNA.

e) It contains both DNA and RNA.

Step-by-step solution

Part (a) Step 1: Given information

We have to tell the given base contains DNA ,RNA or both.

Part (a) Step 2: Explanation

DNA is a nucleotide-rich double- stranded patch with a long chain of nucleotides. RNA is a single- stranded patch with a shorter nucleotide chain than DNA. tone- replicating DNA replicates on its own. RNA is unable of tone- replication.

It contains both DNA and RNA.

Part (b) Step 1: Given information

We have to tell the given base contains DNA ,RNA or both.

Part (b) Step 2: Explanation

DNA is a nucleotide-rich double- stranded patch with a long chain of nucleotides. RNA is a single- stranded patch with a shorter nucleotide chain than DNA. tone- replicating DNA replicates on its own. RNA is unable of tone- replication.

It contains both DNA and RNA.

Part (c) Step 1: Given information

We have to tell the given base contains DNA ,RNA or both.

Part (c) Step 2: Explanation

DNA is a nucleotide-rich double- stranded patch with a long chain of nucleotides. RNA is a single- stranded patch with a shorter nucleotide chain than DNA. tone- replicating DNA replicates on its own. RNA is unable of tone- replication.

It contains RNA.

Part (d) Step 1: Given information

We have to tell the given base contains DNA ,RNA or both.

Part (d) Step 2: Explanation

DNA is a double-stranded, nucleotide-rich molecule containing a long chain of nucleotides. A single-stranded molecule with a shorter nucleotide chain than DNA, RNA is a single-stranded molecule with a shorter nucleotide chain than DNA. DNA that is self-replicating replicates on its own. Self-replication is impossible for RNA.

It has DNA in it.

Part (e) Step 1: Given information

We have to tell the given base contains DNA ,RNA or both.

Part (e) Step 2: Explanation

DNA is a nucleotide-rich double- stranded patch with a long chain of nucleotides. RNA is a single- stranded patch with a shorter nucleotide chain than DNA. tone- replicating DNA replicates on its own. RNA is unable of tone- replication.

It contains both DNA and RNA.
