Adenine and guanine.
What two classes belong to the class of nitrogenous bases called purines?
adenine and cytosine
What are the two Purines in DNA?
two of the bases are purines- adenine and guanine.
Name for large bases containing two carbon-nitrogen rings?
The large bases that have two carbon-nitrogen rings are called purines.
What and what are two classes of nitrogenous bases?
purines and pyramidines.
Which two nitrogenous bases are purines?
Adenine and guanine.
Nitrogenous bases with carbon and nitrogen atoms in two rings?
purines
Which nitrogenous base is composed of two rings?
the nitrogenous base which has double ring structure is purine.it consist two bases adenine and guanine;
What are the two major groups of nitrogenous bases in RNA and DNA?
Purines and Pyrimidines
How many nitrogenous bases are there What are they called?
Four, out of whish 2 purines and two pyremidines
What two classes belong to the class of nitrogenous bases called purines?
adenine and cytosine
What are the purines in DNA are?
two of the bases are purines- adenine and guanine.
What are the two nitrogenous called purines and pyridine?
The two purines are adenine and guanine. The two pyrimidines are thymine and cytosine. Uracil (only in RNA) is also a pyrimidine.
Which two nitrogenous bases are bound by three hydrogen bonds?
Theyre pyrimidines Because Adenine and guanine both have two and cytosine and thymine have one.
What are the four bases found DNA?
adenine----The four nitrogenous bases that comprise DNA are adenine, guanine, thymine, and cytosine. there are four kinds of nitrogenous bases in dna. two of the nitrogenous bases, adenine and guanine,belong to a group of compounds known as purines. the remaining two bases, cytosine and thymine, are know as pyrimidines. Adenine pairs up with thymine, and cytosine pairs up with guanine. Humans also use a fifth base in RNA called uracil. In the case of RNA, thymine is replaced by uracil and other three bases remains the same. All of these bases are attached to the sugar and phosphate. The double helix maintains a constant width because purines always face pyrimidines in the complementary A-T and G-C pairs. And they are all connected by a phosphorous base. A-T; G-C The phosphorous base can be broken for DNA replication purposes.
What are the two Purines in DNA?
two of the bases are purines- adenine and guanine.
