Why is the mRNA code for amino acids said to be redundant?
The code for creating amino acids is said to be redundant because some codons code for the same amino acid (i.e. there is redundancy because several codons have the same function). For example, the RNA codons AAA and AAG both code for the amino acid Lysine. The codons ACU, ACC, ACA and ACG all code for Threonine.
Are there three bases on the mRNA called codons?
All mRNA and DNA sets of three are codons, and rRNA is anti-codons.
How many codons are in aaaugcucguaa?
There are four codons in AAA UGC UCG UAA. A codon is a sequence made of three nitrogenous bases. Codons have particular features, making it possible for them to be start codons, stop codons, introns, or exons.
What is true about codons?
Codons are sequences of three nucleotides in mRNA that specify a particular amino acid. There are 64 possible codons, including start and stop codons. Codons are central to the process of translation, where they are matched with complementary anticodons on tRNA molecules to assemble proteins.
Which codons are the stop signals?
There are three such codons known as stop codons, which are UAA, UAG, or UGA.
Do some codons have no function at all?
Broken condoms work if you tie the end. so no.
What function are carried out by those few condos that do not code for amino acides?
Start sequence and stop sequence codons.

For example, the RNA codons AAA and AAG both code for the amino acid Lysine. The codons ACU, ACC, ACA and ACG all code for Threonine.
How many protein-coding codons are there?
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
Trna has codons or anticodons?
anti-codons for sure!

There are three such codons known as stop codons, which are UAA, UAG, or UGA.
What are codons that do not carry information for making proteins called?
Codons that do not carry information for making proteins are called non-sense codons.
How many different codons are possible with the four different nucleotides?
There are 64 possible different codons (4 nucleotides in a sequence of 3), including 61 codons that code for amino acids and 3 stop codons.
What 3 codons do not carry amino acids?
There are three codons that do not code for any amino acids: the stop codons. These are TAG, TAA, and TGA (in DNA, not RNA).
