Question

RNA is chemically similar to DNA except that its sugars have an additional oxygen atom, and the base thymine is replaced by a structurally similar base called

Select one:
a. codon.
b. cytosine.
c. alanine.
d. uracil.

Answer 1

RNA is chemically similar to DNA, but with some key differences. It contains the base d) uracil instead of thymine, and its sugar is ribose with an additional oxygen atom.

Step-by-step explanation:

RNA is chemically similar to DNA, but it has some key differences. One of the main differences is that RNA contains the base uracil (U) instead of thymine (T) found in DNA.

The sugar in RNA is also ribose, which has an additional oxygen atom compared to the deoxyribose sugar found in DNA.
