Nitrogen Bases in DNA

Answer 1

Macromolecules In addition to the C, the H and the O, they also contain nitrogen (N). All of these elements are arranged to form amino acids. Amino acids are the building blocks ... But, you notice that you have two types of nucleic acids. ... These nitrogenous bases pair up to help form the famous double helix you may have heard about with DNA.

Answer 2

The four nitrogen bases found in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up to form the double helix structure of DNA; adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The sequence of these nitrogen bases along the DNA strand carries genetic information.

Answer 3

Chargaff discovered that the amount of thymin and the amount of guanine always equals the amount of chtosine.

Actually, Chargaff discovered that the amount of THYMINE equaled the amount of ADENINE, and the amount of GUANINE equaled the amount of CYTOSINE.To improve on the last answer, the amount of thymine+guanine DOES NOT equal the amount of cytosine.

Answer 4

Adenosine (A), Thymine (T), Cytosine (C), and Guanine (G).

Answer 5

Erwin Chargaff showed that the ratio of G:C (guanine to cytosine) was 1:1, and that the ratio of A:T (adenine to thymine) was also 1:1.

A and G are purines; T and C are pyrimidines.

Answer 6

He discovered that Cytosine pairs with Guanine which is a pyrimidine base and Thymine pairs with Adenine which is a purine base. :]

Answer 7

Adenine = Thymine

Guanine = Cytosine

Answer 8

Chargaff observed that: # of A = # of T

# of C = # of G

A, C, T, and G are the nitrogeneous bases found in DNA.

Answer 9

The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine

Answer 10

Adenine, thymine, cytosine, guanine.
