Based on the numebr of complementary hydrogen bonds. C (cytosine) bonds with G (guanine) through 3 hydrogen bonds whereas T (thymine) bonds with A (adenine) with only two.
What else can I help you with?
How many purines and pyrimidines are present in the DNA molecule?
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
What nucleotides bond?
In DNA, there are four types of nucleotides. These are Guanine, Cytosine, Thymine and Adenine. Guanine and Adenine are purines whereas Cytosine and Thymine are pyrimidines. Adenine will always bond with thymine in DNA. Therefore, guanine and cytosine bond together. These comnplementary base pairing allows the DNA to be replicated and is also used in protein synthesis.
What are three types of pyrimidines?
Cytosine and thymine are the nitrogenous bases used in DNA. Uracil substitutes for thymine in RNA.
A double-stranded DNA molecule contains a total of 120 purines and 120 pyrimidines This DNA molecule could be composed of?
I don't really understand the point of the question but let's see what we can do. Purines are Adenine and Guanine Pyrimidines are Tyimine and Cytosine Since A pairs with T and G pairs with C, the molecule can be composed of any number of ACTG where A+G=C+T=120 and A=T and G=C Hope that helps.
What is a pyrimidine in biology?
Pyrimidines are single ringed aromatic structures that make up 3 of the basic building blocks of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). Exampes include cytosine, thymine and uracil.
What do purines bond to?
Purines bond to pyrimidines in nucleic acid DNA .
Do purines bond with pyrimidines in Dna?
Adenine and guanine, being purines ( double ringed ) always bond with thymine and cytosine, single ringed pyrimidines.
How is Presence of purines and pyrimidines in DNA found?
Adenine and Guanine are purines, and Thymine and Cytosine are pyrimidines.
How many purines and pyrimidines are present in the DNA molecule?
There are two purines (adenine and guanine) and two pyrimidines (cytosine and thymine) present in the DNA molecule.
What is a part of DNA strand called?
Pyrimidines or Purines
How are pyrimidines different from the purines?
Pyrimidines (cytosine, thymine, uracil) have a single-ring structure, while purines (adenine, guanine) have a double-ring structure. Purines always pair with pyrimidines in DNA and RNA bases. Additionally, purines are larger molecules compared to pyrimidines.
Purines and pyrimidines are?
Purines and pyrimidines are nitrogen bases found in DNA and RNA .They are nitrogen containing heterocyclic compounds .Purines are large double ringed while pyrimidines are small single ringed .
What is the relative percentage of purines to a pyrimidines in a DNA molecule?
In a DNA molecule, the relative percentage of purines (adenine and guanine) to pyrimidines (cytosine and thymine) is approximately 1:1. This means that purines make up roughly 50% and pyrimidines make up the other 50% of the bases in DNA.
How does the number of purines in DNA compare to the number of pyrimidines?
yes
What are you two purines in DNA?
The two purines in DNA are adenine (A) and guanine (G). They are nitrogenous bases that form complementary base pairs with their corresponding pyrimidines (thymine and cytosine) during DNA replication and transcription.
Can purines pair with other purines?
No, purines cannot pair with other purines in DNA or RNA. Purines always pair with pyrimidines through complementary base pairing to maintain the double-stranded structure of DNA. In DNA, adenine (a purine) pairs with thymine (a pyrimidine) and guanine (a purine) pairs with cytosine (a pyrimidine).
What is the diameter of the DNA double helix?
Purines always bond with Pyrimidines.
