What are the four bases found in DNA?

Answer 1

The four nitrogenous bases found in DNA are adenine, thymine, guanine and cytosine.

Answer 2

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.

Answer 3

Adenine which pairs with Thymine, and guanine which pairs with cytosine.
adenine (A), cytosine (C), guanine (G) and thymine (T).
Adenine, Guanine, Thymine and Cytosine are the foure bases in DNA.

Answer 4

The four nitrogenous bases found in DNA are: Adenine, Guanine, Cytosine and Thymine. Adenine and Guanine are purines whereas Cytosine and Thymine are pyrimidines. Uracil is found in RNA and is also a pyrimidine. Use this mnemonic, CUT PY (like cut pie), Cytosine, Thymine, Uracil are PYrimidines.

Answer 5

A DNA molecule looks a bit like a twisted ladder. The sides of the ladder are made up of alternating ribose and phosphate groups. The rungs of the ladder are paired nitrogenous bases, A, C,T, and G. A will always pair up with T, and C will always pair up with G.

Answer 6

The four bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up to form the "rungs" of the DNA double helix through specific hydrogen bonding: A pairs with T and C pairs with G.

Answer 7

Adenine and guanine are purines (double ring).

Cytosine and thymine are pyrimidine (single ring).
