The DNA molecules will have 450 thymines if a DNA molecule has a total of 1500nucleotides
A DNA molecule also known as deoxyribonucleic acid is made up of a double helix.
The DNA molecule with a total of 1500 nucleotides will contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
This shows that the DNA molecules will have 450 thymines
