Why are there always the same number of adenine and thymine in a molecule?
Chemical analysis has shown that the number of adenine molecules in a sample of DNA is always the same as the number of thymine molecules. A sample of RNA would show that there are equal numbers of adenine molecules and uracil molecules.
Which molecules make up the horizontal rungs of a DNA ladder?
Uracil, adenine, thymine, and cytosine.
What are the units that's form DNA molecules?
They are the nucleotides adenine, guanine, cytosine, and thymine.
Ifa DNA triplet is CTA then what is the complimentary DNA?
Because Cytosine attaches with Guanine and adenine attaches with thymine, if CTA (cytosine, thymine, adenine) had another strand of DNA it should read GAT however mutations can occur.
What is a base that forms with thymine?
DNA!! the matching strands of rna form dna..
What base can adenine pair?
In DNA, adenine pairs with Thymine In RNA, adenine pairs with Uracil The code letters are A, T, G, C, which stand for adenine, thymine, guanine, and cytosine. These four chemicals create DNA.
Four molecules of rungs in DNA what are they called?
they are adenine , guanine , thymine , cytosine ..
What are six molecules compose DNA?
adenine, thymine, cytosine, guanine, and deoxyribose
What are units that form that DNA molecules?
They are the nucleotides adenine, guanine, cytosine, and thymine.

Which molecules make up the horizontal rungs of a DNA ladder?
Uracil, adenine, thymine, and cytosine.
What molecules are found in a DNA nucleotide?
Guanine which binds with Cytosine, and Adenine which binds with Thymine.
What are the units that's form DNA molecules?
They are the nucleotides adenine, guanine, cytosine, and thymine.
Why are guanine and cytosine and they and adenine useful in the DNA molecules?
Guanine is a purine and Cytosine is a pyrimidine. They are nucleotides that pair together. The two are useful in DNA molecules because they pair together, along with Adenine and Thymine, which build a double helix. Guanine, Adenine, Thymine, and Cytosine are all nitrogenous bases.
Is DNA made of molecules?
Yes. DNA is made out of the nitrogenous bases (adenine, guanine, thymine and cytosine) and a phospholipid backbone.
Is uracil always paired with adenine in double-stranded DNA?
No, Uracil doesn't occur in double stranded DNA. Doublestranded DNA contains Guanine paired with Cytosine and Adenine paired with Thymine. In RNA, however, Adenine is always paired with Uracil instead of Thymine.
What are the four nitrogen bases that are found in all DNA molecules?
Adenine,Thymine,Cytocine,Guanine
