What are you two purines in DNA?
Adenine and guanine are the two purines in the DNA and thymine and cytosine are two pyrimidines.
What is the relative percentage of purines to a pyrimidines in a DNA molecule?
1:1
What are adenine and guanine and cytosine classified as?
Nitrogenous bases, either purines or pyrimidines.
What are the purine bases and pyrimidine bases?
They are the nitrogen bases that are attached to RNA and DNA. In DNA, adenine and guanine are purines and thymine and cytosine are pyrimidines. In RNA, thymine is replaced by pyrimidine uracil.
What molecules make up the rungs of a DNa ladder?
purines, pyrimidines, nucleotides and nitrogen bases.
How do purines differ from pyrimidines?
Purines and pyrimidines are the building blocks of nucleic acids. The difference between purines and pyrimidines is in the number of carbon-rings present. Pyrimidines contain one carbon-ring while purines have two.
What is the difference between a purines and pyrimidines?
A purine has a double ring, while a pyrimidine has a single ring. Also purines are adenine and guanine, and the pyrimidines are thymine and cytosine.
Which one is purines and pyrimidines are bigger?
Purines because purines have two rings where as pyrimidines have only one ring.
How is Presence of purines and pyrimidines in DNA found?
Adenine and Guanine are purines, and Thymine and Cytosine are 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 do purines bond to?
Purines bond to pyrimidines in nucleic acid DNA .
Can purines pair with other purines?
No. The physical structure does not allow purines to pair with other purines. Purines can only be paired with Pyrimidines.
Do purines bond with pyrimidines in Dna?
Adenine and guanine, being purines ( double ringed ) always bond with thymine and cytosine, single ringed pyrimidines.
What macro molecule has pyrimidines and purines?
Nucleic acids
What are the two classes of nitrogen bases?
Purines and pyrimidines
What is a part of DNA strand called?
Pyrimidines or Purines
Who discovered there are purines and pyrimidines?
Sir David Dashery
