Erwin Chargaff's work on the composition of nucleic acids began in 1944. His findings, which later became known as Chargaff's rules, detail the specific pairings that occur in double-stranded DNA molecules.

According to one of Chargaff's rules, a section of DNA molecule that contains 50 base pairs and has 15 adenine bases must also contain -

A. 15 guanine bases

B. 15 cytosine bases

C. 15 thymine bases

D. 15 uracil bases

Answer:

C: 15 thyme based

Explanation:

DNA molecule

A=T

Chargaff's rule of base pairing is an important rule for DNA nucleotide sequencing and is crucial in genetics. He gave the most important rules in his findings of the nucleotide base pairing.

DNA molecule that contains 50 base pairs and has 15 adenine bases must also contain option C. 15 thymine bases.

The bases can be explained as:

  • According to Chargaff, bases containing purine and pyrimidine should be in 1:1 proportionate universally.

  • The number of purine adenine would be equal to pyrimidine thymine and purine guanine would be equal to pyrimidine cytosine in a DNA sequence.

Therefore, 15 adenine will base pair with 15 thymine bases.
