What is the number of hydrogen bonds in B DNA of 1000 base pairs?

What is the number of hydrogen bonds in B DNA of 1000 base pairs?

About 2150 H bonds present.

What is the number of hydrogen bonds in B DNA?

As per the Watson-Crick structure, three hydrogen bonds can form between G and C, and only two can form between A and T. Hence, there are 600 Cs that will pair complementary to G on the other strand with three hydrogen bonds.

How many H bonds are present between cytosine and guanine?

three hydrogen bonds
Cytosine and guanine pairing can be found in both DNA and DNA-RNA hybrid formed during replication and transcription. The two nitrogenous bases are held together by three hydrogen bonds.

How many H bonds are present in DNA between adenine and thymine?

two hydrogen bonds
Base pairing between adenine and thymine can be found in DNA only. There are two hydrogen bonds holding the two nitrogenous bases together.

Which bond is present between guanine and cytosine?

The guanine forms three hydrogen bonds with the cytosine because, In cytosine, the amino group acts as the hydrogen bond donor and the C-2 carbonyl and the N-3 amine as the hydrogen-bond acceptors and in Guanine the group at C-6 acts as the hydrogen bond acceptor, while the group at N-1 and the amino group at C-2 act …

How many H bonds are present between the complementary strands?

The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.

How many Guanines are found in a Dsdna that has 700 hydrogen bonds and 10\% adenine?

From your question it seems unclear whether 10\% of the bases are Adenine or if 10\%of the total H-bonds are from Adenine. Anyway,I will answer it in both the cases. now solving we get,n=500,as G=40\%of n,so G=200.
