A double-stranded DNA molecule contains 30 percent guanine (G) What is the percent cytosine (C) in this molecule?
If the DNA macromolecule contains 20% G (guanine), then by Watson-Crick complementarity it must contain 20% C (cytosine). Together this equals 40%, so the percent that is A (adenine) and T (thymine) together is 60%. By Watson-Crick complementarity, then, the percent A in the molecule is half of 60: 30%.
What else can I help you with?
Which bases does Guanine always bond with to form a pair in DNA?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
In a DNA molecule guanine would connect to?
What does guanine connect to in a dna molecule?
What is a molecule found in all DNA and RNA bases?
The nitrogen bases themselves are molecules. DNA and RNA both contain the nitrogen bases adenine, guanine, and cytosine. DNA contains the nitrogen base thymine, while RNA contains the nitrogen base uracil instead.
Do uracil always pair with cytosine in the RNA molecule?
Cytosine is always coupled with Guanine. (I like to remember that the round letters stick together).In DNA, Thymine is coupled with Adenine, but in RNA, Thymine is replaced by Uracil.Therefore, in RNA, U and A go together, always.
Which two bases are present in equal amounts in a double-stranded DNA molecule?
The two bases that are present in equal amounts in a double stranded DNA molecule are cytosine and guanine. Cytosine pairs with guanine in A DNA molecule.
A double-stranded DNA molecule contains 30 percent guanine What is the percent cytosine in this molecule Where is the promoter region?
30 percent
What nucleotide bonds with guanine?
Guanine bonds to Cytosine in DNA through three hydrogen bonds. It also bonds to a Deoxyribose molecule in the backbone of the DNA molecule.
