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.

What are the nitrogen bases found in RNA and what do they bond to?

Adenine and Uracil, which pair together (Uracil takes the place of Thymine from DNA) Guanine and Cytosine, which also pair together


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.


What is the base unit of a nucleic acid?

The nitrogenous base units of a nucleic acid are Adenine, Cytosine, Guanine, and Thymine. (in Dna) in RNA Thymine is replaced with Uracil. These base pair are often abreviated to A,C,T,G, and U. Adenine will always pair with Thymine. Cytosine will always pair with guanine.


What is the rule of pairs for DNA?

Chargaff's rule states: Adenine will always pair with Thymine in DNA; Guanine will always pair with Cytosine in DNA. Note: In RNA, no thymine is present, and its replaced by uracil; therefore, in RNA, Adenine pairs with Uracil.


What are the DNA base pairing rules?

Adenine always pairs with thymine Cytosine always pairs with guanine.


What base will always pair with another base?

A purine will always pair with a pyrimidine. Examples of purines are adenine (pairs with thymine or uracil) and guanine (pairs with cytosine). Examples of pyrimidines are thymine (pairs with adenine), uracil (pairs with adenine), and cytosine (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 the base pairing rules of rna?

RNA base pairing rules are similar to DNA, except uracil (U) pairs with adenine (A) instead of thymine (T). This means in RNA, adenine pairs with uracil, cytosine pairs with guanine, and guanine pairs with cytosine.


What is the base pair rule for DNA?

In DNA the base pairs are Adenine with Thymine and Guanine with Cytosine. In RNA Thymine is replaced by Uracil so the base pairs are Adenine with Uracil and Guanine with Cytosine.


What are the pyrimidine bases of RNA?

Thymine and cytosine are the pyrimidine bases of DNA. Uracil is the pyrimidine base which replaces thymine in RNA.


What are nuclotides on DNA molecule called?

A is for Adenosine, T is for Thymine, G is for Guanine and C is for Cytosine. For RNA, U is for Uracil


What belong to the class of nitrogenous bases called pyrimidines?

The pyrimidines are a class of nitrogenous bases that includes cytosine, thymine, and uracil. These bases are found in nucleic acids like DNA and RNA, where they pair with complementary purines to form the building blocks of genetic information.
