A segment of dna molecule comprises of 546 nucleotide how many cytosine nucleotides would be present in it if the number of adenine nucleotides is 96
Answers
your answer is in the above picture.
based on chargaff rule number of adenine molecule is equal to number of thymine molecule
number of guanine is equal to number of cytosine.
so A+G/T+C=1.
hope the answer is helpful.
177 nucleotides are cytosine in the DNA segment having 546 nucleotides in total.
Explanation:
Total number of nucleotides in the segment of a DNA molecule is 546 nucleotides.
If 96 adenine nucleotide is present in the segment then thymine will also be in the same quantity as per with Chargaff' Rule.
Chargaff rules states that A+G = C+ T
the purine and pyrimidine are always in the ratio of 1:1.
Guanine= cytosine
Adenine = Thymine
so, 96 + 96 = 192 nucleotides are adenine and thymine
Now from the total 192 is deducted
546-192
= 354 nucleotides are guanine and cytosine
dividing them into two as cytosine bonds with guanine we get
177 nucleotide are cytosine in the DNA segment.
