This is the tricky one to remember: RNA nucleic acids contain uracil and not thymine. On DNA, adenine pairs with thymine, but on RNA, adenine pairs with uracil.

There are four nitrogen bases in mRNA, adenine, uracil, cytosine and guanine.

It will use adenine, but thymine will be replaced by a nitrogen base called "uracil" in mRNA

Uracil replaces Thymine as a base in mRNA.

It's not a strand that is replaced, but a nitrogen base, much like adenine. The pyrimidine thymine is replaced by another pyrimidine uracil.

During transcription, the resulting bases on the mRNA if the DNA has the base adenine is Proteins.

Adenine, Uracil, Cytosine, Guanine (uracil replaces thymine in mRNA)

It would be: Cytosine Adenine Cytosine Uracil Uracil Guanine Cytosine Adenine Cytosine

There are 4 nitrogenous bases characteristic of mRNA. Adenine, Cytosine, Uracil, and Guanine.

His is histamine, Ser is Serine, and Arg is Arginine. The mRNA codons are Adenine, guanine, cytosine, and uridine, which replaces thymine in the original DNA code.

The four nitrogenous bases in DNA are: adenine, guanine, cytosine and thyamine. The pairs are: A-T and G-C.a-tt-ac-gg-cDNA replication follows complementary base pairing principle. According to this principle adenine pairs with thymine and guanine pairs with cytosine. n case of RNA, thymine is replaced by uracil.(see what each base stands for below)a= adeninet=thyminec=cytosineg=guanineAdenine will always pair up with Thymine and Guanine will always pair up with Cytosine. An example is A(which stands for Adenine) would pair up with ___?___ ? would equal T(which stands for Thymine).The bases pair by hydrogen bonds. Adenine and thymine pair by two hydrogen bonds and cytosine and guanine pair by three.AnswerBy matching the mRNA strand with the right mRNA strand.

The four nitrogen bases in DNA are adenine, guanine, cytosine, and thymine. Adenine pairs with thymine, and guanine pairs with cytosine. The four nitrogen bases in RNA are the same as DNA, except that the base uracil replaces thymine, and adenine pairs with uracil instead of thymine.Thymine pairs with Adenine and Guanine pairs with Cytosine.A to T and C to G Adenine and Guanine are purines and Cytosine and Thymine are pyrimidinesSimple, adenine pairs with thymine and guanine pairs with cytosine.A-t,cgAdenine pairs with thymine.Guanine pairs with cytosine.Hydrogen bonds between the bases A-T has 2 hydrogen bonds, C-G has 3 Hydrogen bonds.Adenine and Thymine, Guanine and Cytosine.

Mutation would occur in the cell if there was an extra nitrogen base deleted from the mRNA code.

Before mRNA leaves the nucleus, it must go through a process called transcription. As DNA is being unzipped during replication, a strand of mRNA pairs up with each of the two DNA strands - creating a total of two mRNA strands. When mRNA is being transcribed from the DNA, the nitrogen base A is paired up with the nitrogen base U, nitrogen base T is paired up with A, nitrogen base C is paired up with G, and nitrogen base G is being pared up with the nitrogen base C. Example: DNA - A T C G T A A T G C *** TRANSCRIPTION*** mRNA - U A G C T U U A C G -> mRNA is now ready to leave the nucleus

The process is called DNA Transciption. It is when the DNA is copied into mRNA using base pairing - Adenine to Thymine, Guanine to Cytosine. Only the problem here is that when using mRNA, Thymine is replaced with a different nucleotide represented by a U. This is what we need the answer for. Its Uracil...

Nucleotides. There are 4: Adenine, Cytosine, Thymine, and Guanine in DNA and mRNA. In tRNA, the 4 nucleotides are Adenine, Cytosine, Uracil and Guanine.

Adenine with Thymine (or Uracil for mRNA)andCytosine with Guanine.

mRNA contains the following bases: guanidine (G) cytosine (C) adenine (A) uracil (U) The precise sequence of bases in any given mRNA is determined by the DNA sequence from which the mRNA was transcribed.

AUGremember the base pairing rules...the only differences in mrna is that Adenine binds with uracil because thymine does not exist in mRNAA=UT=AC=G

The three nitrogen bases on the mRNA are called codon, and on tRNA they are called anticodon.

Adenine and uracil pair together, and guanine and cytosine pair together. In mRNA, adenine pairs with thymine in DNA during transcription.

Its basically the same for RNA and DNA, except that in RNA instead of Thymine its, Uracil. So the nitrogen bases for RNA are: URACIL ADENINE CYTOSINE GUANINE

A 3-base sequence of nitrogen bases on a molecule of mRNA is called a codon.

Cytosine only matches with guanine, and adenine only matches with uracil (thymine in DNA).
