No.

Adenine binds to Thymine
Guanine binds to Cytosine

This means that the number of A=T and G=C

A + G = T + C - but the number of G and T can be different.

Why do you think were equal parts of guanine and cytosine and equal parts of adenine and thymine in DNA of a cell?

There are equal parts of guanine and cytosine, and adenine and thymine, because they form base pairs in the DNA molecule. This is in accordance with the base-pairing rule, which states that in DNA, adenine always pairs with thymine, and guanine always pairs with cytosine.


What nucleotide basis are present in equal amounts of DNA?

The nucleotide bases guanine and cytosine, and adenine and thymine are present in equal quantities in DNA. This is how scientists determined that guanine pairs with cytosine, and adenine pairs with thymine.


The amount of adenine will always equal what?

adenine In a DNA strand, the amount of Adenine equals the amount of Thymine, and the amount of Guanine equals the amount of Cytosine. So Adenine is your answer.


Did Watson's and crick's model account for the equal amounts of thymine and adenine in DNA?

Yes because they always paired thymine with adenine or always paired adenine with thymine, never pairing either with cytosine or guanine. Therefore they are in equal amounts.


What are the DNA base pairing rules?

Adenine always pairs with thymine Cytosine always pairs with guanine.


What nitrogen base always pairs up with adenine?

adenine with thymine cytosine with guanine adenine with uracil cytosine with guanine


What are nucluetides in DNA?

There are four nucleotides in DNA.Adenine and Thymine always match up.Cytosine and Guanine always match up.


Which bases always pair on DNA?

Adenine pairs with thymine and guanine pairs with cytosine


On dna what base will always pair with what base?

Adenine always pairs with thymine in a DNAmolecule.


What are four nitrogen bases on DNA?

The four nitrogenouse bases found in DNA are adenine, thymine, cytosine, and guanine. When they are paired up it's always adenine to thymine, guanine to cytosine, thymine to adenine, and cytosine to guanine. They can't be mismatched such as adenine to guanine or cytosine


What makes up the rungs of the ladder of DNA?

The nitrogenous bases Adenine, Thymine, Guanine, and Cytosine Adenine and Thymine are always together and Cytosine and Guanine are always together.


According to the DNA base pairing rules cytosine always bonds with what?

In DNA adenine pairs with thymine. In RNA adenine pairs with uracil.
