Chargaff's law states that the bases Adenine and Thymine must be equal, and Cytosine and Guanine must be equal.

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


What is the correct term for a group of three nitrogenous bases in DNA or mRNA that code for one amino acid?

Codon.


How many nitrogenous bases are found in a anticodon?

3. The opposite three that are located on the codon of an mRNA strand.eg.If mRNA reads CAG UCG AGU Three codonsThen tRNA GUC AGC UCA Three Antiocodons each containing three nitrogenous bases.


What are 3 bases on tRNA called?

I'm not completely sure but I think it's uracine, glycine, cytosine, and adenine. But that's 4


How many bases does RNA have?

3 nitrogenous bases form one "word" of a mRNA's message.


What are the bases on the mRNA strands are called?

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


How do dna bases pair up with mrna bases?

The mRNA bases are complementary to the DNA bases, and so form H-bonds when the DNA is single-stranded. DNA - mRNA A - U T - A C - G G - C


How many bases are needed to specify an mRNA codon?

3 bases are needed to specify an mRNA codon.


Why are some ribosomes located on rough ER?

mRNA binds to the ribosomes on the rough endoplasmic reticulum in order to form proteins. tRNA collects and binds amino acids according to the arrangement of nitrogenous bases in mRNA bound to the ribosomes on the RER. Without the ribosomes, mRNA wouldn't be able to bind to the RER and the translation stage of protein synthesis wouldn't be able to occur.


How did you know which bases to use when you transcribed the DNA sequence to mRNA codons?

In transcription, the mRNA strand is formed by complementary base pairing of the template DNA strand. However we should note that the nitrogenous bases in mRNA are Adenine, Guanine, Cytosine and Uracil, while those in DNA are Adenine, Guanine, Cytosine and Thymine.So the mRNA strand would be formed by matching the A in DNA with U in mRNA, T in DNA with A in mRNA, C in DNA with G in mRNA and G in DNA with C in mRNA.I hope that helps!


What nitrogenous base is not found on DNA but is found on RNA?

Thymine is not found in RNA. It is instead replaced by Uracil.


What determines the sequence of bases in mRNA?
