Question

Which of the following statements accurately describes a similarity between the nucleotides of DNA and RNA? a) DNA nucleotides contain ribose sugar, while RNA nucleotides contain deoxyribose sugar. b) Both DNA and RNA nucleotides consist of adenine (A), cytosine (C), and guanine (G). c) DNA nucleotides use uracil (U) as a base, while RNA nucleotides use thymine (T). d) DNA nucleotides are single-stranded, while RNA nucleotides are double-stranded.

Answer 1

The similarity between the nucleotides of DNA and RNA is that they both consist of adenine (A), cytosine (C), and guanine (G). The fourth type of nucleotide in DNA is thymine (T), while in RNA, it is uracil (U). DNA is usually double-stranded, and RNA is single-stranded. Therefore the correct option is B

Step-by-step explanation:

The correct answer to your question, 'Which of the following statements accurately describes a similarity between the nucleotides of DNA and RNA?' is option b) Both DNA and RNA nucleotides consist of adenine (A), cytosine (C), and guanine (G).

DNA and RNA are both made up of nucleotides, which are molecular structures that combine to form the genetic material within every living organism. Despite several critical differences between the two types of nucleotides, they do share the commonality of adenine, cytosine, and guanine. Option b) is correct because both DNA and RNA use these three types of nucleotides in their strands. However, when it comes to the fourth type of nucleotide, DNA uses thymine (T), while RNA uses uracil (U), not as stated in option a) or c). Moreover, the structure of DNA and RNA differs as DNA is typically double-stranded, and RNA is single-stranded, contradicting option d).
