Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).

Answer:

6 thymine, 4 guanine. 4 cytosine

Explanation:

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)
