Question

a scientist knows that a molecule of DNA is 27% cytosine what else does the scientists know about the DNA molecule? ​

Answer 1

guanine:27%

thymine:23%

adanine:23%

Step-by-step explanation:

cytosine connects with guanine meaning that they will have the same amount of bases and adanine and thymine are both 23% because they connect to each other and 27+27 is 54 and 100-54 is 46 and 46/2 is 23 making them both 23%.

Answer 2

It is 27 % guanine.

Step-by-step explanation:

They also know that cytosine always pairs off with guanine.

If the molecule is 27 % cytosine, it must also be 27 % guanine.
