# What would be the percentage of cytosine in the DNA that has 30% adenine?

## What would be the percentage of cytosine in the DNA that has 30% adenine?

There would be 20% Cytosine. Adenine (30%) = Thymine (30%) Guanine (20%) = Cytosine (20%) Therefore, 60% A-T and 40% C-G.

## Which bases are found in A strand of DNA?

Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T).

Where is cytosine and guanine found?

Cytosine (C) is one of four chemical bases in DNA, the other three being adenine (A), guanine (G), and thymine (T). Within the DNA molecule, cytosine bases located on one strand form chemical bonds with guanine bases on the opposite strand. The sequence of four DNA bases encodes the cell’s genetic instructions.

What is the percentage of adenine in E coli?

The table clearly shows that the percentage of adenine in each organism’s DNA is different, ranging from 24.7% in E. coli to 33.2% in the octopus.

### What percent of DNA is cytosine?

18%
In a DNA molecule cytosine is 18%. Percentage of adenine would be—— a. 32%

### How much adenine guanine and cytosine are present if a DNA strand contains 20% thymine?

Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%.

Why is DNA measured in base pairs?

The size of an individual gene or an organism’s entire genome is often measured in base pairs because DNA is usually double-stranded. Hence, the number of total base pairs is equal to the number of nucleotides in one of the strands (with the exception of non-coding single-stranded regions of telomeres.

Is guanine found in DNA?

Guanine (G) is one of four chemical bases in DNA, with the other three being adenine (A), cytosine (C), and thymine (T). Within the DNA molecule, guanine bases located on one strand form chemical bonds with cytosine bases on the opposite strand. The sequence of four DNA bases encodes the cell’s genetic instructions.

#### Where is guanine found?

acids DNA
Guanine (/ˈɡwɑːnɪn/) (symbol G or Gua) is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA). In DNA, guanine is paired with cytosine.

#### What percentage of DNA is adenine?

In a DNA sample, the percentage of adenine is 40% and percentage of thymine is 60%.

What is the percentage of bases in DNA?

The final composition is 22% adenine, 22% thymine, 28% cytosine, and 28% guanine.
