DNA contains two types of nitrogen bases. There are the purines, which include Adenine and Guanine, and the pyrimidines, which include Thymine and Cytosine.

Adenine ALWAYS bonds with Thymine, and Guanine ALWAYS bonds with Cytosine, unless, of course, we have a mutation.

True or false Only DNA molecules contain the nitrogen base called uracil?

False. Uracil is a nitrogen base found in RNA molecules, not DNA. In DNA, thymine is the equivalent nitrogen base to uracil.

The nitrogen base thymine in DNA is replaced by the nitrogen base uracil in RNA.


Which nitrogen base is missing in DNA?

Uracil is the nitrogen base that is missing in DNA. In DNA, thymine replaces uracil as one of the four nitrogen bases.

uracil


What is the base of nitrogen DNA?

The nitrogen bases for DNA are adenine, guanine, cytosine, and thymine


Does a gene contain uracil?

The nitrogen base uracil is not present in DNA. It is only present in RNA and is used as a substitute for thymine


What base is missing on RNA and what other base replaces it?

No nitrogen base is missing. You may be referring to the fact that DNA contains the nitrogen base thymine, while RNA contains the nitrogen base uracil. They both contain adenine, cytosine, and guanine.


What elements form a nitrogen base?

A nitrogen base is formed from nitrogen atoms and other elements such as carbon, hydrogen, and oxygen. These elements are arranged into specific structures like adenine, cytosine, guanine, thymine, and uracil, which are key components of DNA and RNA molecules.


What nitrogen base is found in RNA that pairs with adenine in DNA?

Uracil is the nitrogen base found in RNA that pairs with adenine in DNA.


3 DNA does NOT contain the nitrogen base?

DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil


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.


What nitrogen base has 3 bonds?

Ammonia? Or are you reffering to DNA in which case Guanine base pairs with Cytosine by forming 3 hydrogen bonds.
