How much cytosine is present in DNA if there is 15\% of adenine?

According to Chargaffs rule, the total amount of adenine released is equal to the total amount of thymine and the total amount of cytosine is equal to the total amount of guanine, ie, A = T and C = G. Thus, if DNA molecule contains 15\% adenine then C and G will constitute 70\%, out of which guanine will be 35\%.

How many cytosine bases does DNA contain?

There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).

Does DNA contain cytosine?

Cytosine is one of the four building blocks of DNA and RNA. So it’s one of the four nucleotides that’s present both in DNA, RNA, and each cytosine makes up part of the code. Cytosine has the unique property in that it binds in the double helix opposite a guanine, one of the other nucleotides.

Is cytosine in DNA or RNA?

What elements make up cytosine?

As a nitrogenous base, cytosine is full of nitrogen atoms (it has three). It also has one ring of carbon, which makes it a pyrimidine. A purine, on the other hand, has two rings of carbon.

What are the percentages of adenine and cytosine in DNA?

In DNA, adenine (A) always bonds with thymine (T), while guanine (G) always bonds with cytosine (C). So, the percentages of A and T will be equal, while the percentages of G and C would also be equal. In this sample, there exist 10\% of guanine, therefore there’s also 10\% of cytosine.

What is the percentage of thymine in this DNA sample?

In this sample, there exist 10\% of guanine, therefore there’s also 10\% of cytosine. Therefore, thymine and adenine would make up a total of 100\% −10\% − 10\% = 80\% of the DNA. As they must exist in equal amounts, the percentage of thymine in this DNA sample will be 80\% ÷ 2 = 40\%.

What is the ratio of cytosine to guanine in DNA?

If guanine=10\% as guanine will always pair with cytosine, i.e.cytosine is also 10\% then adenine and thymine accounts 80\% as adenine will always pair with thymine. 5. If the ratio (A+G)/ (T+C) in one strand of DNA is 0.7, what is the same ratio in complementary strand.?

What is the concentration of adenine in 40\% of thymine?

According to Chargaff’s rule, Concentration of adenine=concentration of thymine. therefore if [A]=40\% then the [T] will also be 40\%.
