What are the three parts of a nucleotide? (monomer of DNA)

You are studying a strand of DNA:

5’-AAAGTTCGA-3’

Which of the below choices is a complimentary strand to the one shown above.

• 3' TTTCAAGCT 5'

• 3' UUUCAAGCU 5'

• 5' TTTCAAGCT 3'

• 5' UUUCAAGCU 3'

Organize the 5 possible nitrogen bases in nucleic acids into the right categories.

Groups:

(a) Purines

,

(b) Pyrimidines

• Guanine

• Cytosine

• Thymine

• Adenine

• Uracil

The genome of a new organism contains 17% A - adenine.

What percentage of T, C, and G does the genome contain?

Be sure to label each % in your response.

Answer explanation

In double‑stranded DNA: A pairs with T and C pairs with G, so the percentages of A and T must be equal, and the percentages of C and G must be equal.

If A=17%, then T=17% as well. Therefore, A+T accounts for 34% of the DNA.

The remaining percentage must be split equally between C and G.

100% - 34% = 66%

66% / 2 = 33%

So, C and G each make up 33% of the DNA.
