Adenine,Thymine,Guanine,and Cytosine!
purines, pyrimidines, nucleotides and nitrogen bases.
The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.
The "rungs" of DNA are the nitrogenous bases (Adenine, Thymine, Cytosine and Guanine). To make the rungs - A binds to T and C binds to G.
In you ladder analogy it would be the rungs. About half is each rung is one base (the other half being is pair obviously)
Adeninine - Thiamine and Guanine - Cytosine pairs.
what are 4 bases that make up the rungs of the DNA ladder
what are 4 bases that make up the rungs of the DNA ladder
The rungs of the DNA ladder are composed of alternating deoxyribose sugar molecules and phosphate groups.
phosphate and sugar
The rungs that are in the DNA ladder molecule are nucleotides. They are adenine, guanine, thymine and cytosine. Deoxyribose and phosphate make up the backbone of the molecule.
Phospate groups and dioxyribose sugars. the "rungs" are made up of the four nitrogen bases--adenine, thymine, guanine and cytosine.
thymines, guanines, adenines, and cytosines
purines, pyrimidines, nucleotides and nitrogen bases.
What four molecules make up the rungs of the ladder
The nitrogenous bases Adenine, Thymine, Guanine, and Cytosine Adenine and Thymine are always together and Cytosine and Guanine are always together.
The sides of the DNA ladder is composed of sugar and phosphate. 4 bases that make up the rungs of the DNA ladder are A, T, G, and C. The shape of the DNA is a double helix or twisted ladder.
Phosphate and sugar make up the sides of a DNA ladder.
