If an mRNA is made up of 60 bases how many codons does it contain and how many amino acid does it code for?

A codon is exactly three bases long, so an mRNA strand with 60 bases would contain 20 codons. The first codon will encode for methionine (this is called the "start" codon) and the last codon will be a "stop" codon, which does not encode for an amino acid. Thus, an mRNA strand of 60 bases will code for 19 amino acids.
Keep in mind, it is possible for a stop codon to be anywhere on the mRNA strand, and when a stop codon reaches the ribosome, translation must stop. For example, if an mRNA strand contained 30 codons, and the 15th were a stop codon, the mRNA would only code for 14 amino acids and then be done. The other 15 codons would go untranslated.

The genetic code is universal but what does this mean?
this means that the same genetic code that is used in humans is used in all other types of organisms as well. anything from animals to plants to bacteria uses the same system of triplet nucleotide bases (codons) to code for a single amino acid when building a polypeptide. remember that the genetic code is also degenerate- each codon only codes for one amino acid, but there can be several different codons that call for the same amino acid.
What about the degenracy of genetic code?
Type your answer here... the degenracy of code means there are more than one codons for one amino acid.The opposite of it ie.non-degeneracy of codon means ther is only one codon for one amino acid.
What are the Feature of genetic code?
it is made of a sequence of nucleotides:in DNA or RNA, these nucleotides are adenine, guanine, cytosine, and uracil where it determines the specific amino acid sequence in the proteins,but is the biochemical of heredity and nearly universal in all organisms... DNA transfers and forms a code.
What are the Triplet codes of three bases are the genetic codes used in transmitting genetic information necessary for?
Codons code for a particular amino acid with a triplet of DNA nucleotides.There are 20 amino acids, and 4 nucleic acids. Using a single base you could only code for 4/20, with two bases 16/20, 3 bases 64/20. Therefore 3 bases are necessary to encode all of the possible amino-acids.
What is the genetic code read in?
Three-base triplets called codons. Each codon will be translated into an amino acid during the process of translation.
How many codons are needed to specify 2 amino acids?
each codon have 3 nitrogenous bases . 3 nitrogenous bases = 1 amino acid or say 1 codon =1 amino acid ,so 2 codon = 2 amino acid
How do amino acids specify codons?
Nucleutoides.
Is it 1 or 3 codons equal one amino acid?
One. A codon, made up of three DNA bases (ATG, for example) corresponds to one amino acid. A whole bunch of codons strung together on the DNA corresponds to a whole bunch of amino acids, ultimately strung together to form a peptide, or protein.
What does an amino acid table show?
Amino acid tables are used to translate mRNA codons into amino acid sequences. They also tell whem mRNA codons produce stops.
How many bases do codons have?
Codons are made up of three bases/nucleotides in DNA or mRNA. Each codon encodes an amino acid or signifies a stop signal. Hope that helps!
The genetic code for one amino acid molecule consists of?
The genetic code for one amino acid is called a codon, and consists of a three nucleotide sequence. Codons don't always code for an amino acid, there are also start codons and stop codons that help the body determine where the genetic code for a specific protein starts and stops.
Does every codon represent an amino acid?
No, not every codon represents an amino acid. There are several codons known as "stop" codons (UGA, UAA, UAG) that do not code for an amino acid; instead they code for the termination of translation.
How many bases are needed to make 3 amino acids?
One codon is 3 bases long - this codes for one amino acid. Therefore you would need 9 bases (3 codons) to make 3 amino acids.
How do nucleotide bases form a code?
The bases, taken three at a time, form triplets known as codons that each represent one amino acid. Since there are four bases, there are 4^3 = 64 possible codons, each of which represents one of 20 amino acids. Thus the code has built-in redundancy, i.e., some codes can be altered by mutation without affecting which amino acid is coded for.

When the four DNA bases are combined in triplets different what of the protein are called for?
Amino Acids? I'm not positive but I'm working on the packet and have the same question.
What the possible codons for the amino acid proline?
proline!
