If an RNA strand has 20 adenine bases, how many thymine bases would it have?

Question 5 options:

A)
20


B)
40


C)
none, because RNA does not have thymine

Respuesta :

Answer;

C)  none, because RNA does not have thymine

Explanation;

  • Both DNA and RNA are nucleic acids that are very important in all living cells. However, they differ structurally and function wise.
  • The structural difference include; DNA is double stranded while RNA is single stranded, DNA contain deoxyribose sugar while RNA contains ribose sugar. Additionally, DNA contains the nucleotide bases, Adenine, Guanine, Thymine, and Cytosine, while RNA contains nucleotide bases; Adenine, Guanine, Cytosine and Uracil.
  • Therefore, the base Thymine in DNA is replaced by the base Uracil in RNA, thus Adenine pairs with Uracil in the case of RNA, and thus the nummber of Adenine bases is equal to that of uracil bases in RNA.
