If a section of mRNA contains 144 nucleotides how many codons does it contain?
Codons are read in triplets (3) so divide 144 by 3
Which molecule contains protein building instructions?
DNA
The sequences of amino acids that make up a protein molecule are specified by?
codons
On what molecule would you find the codon?
A codon is a set of three nucleotides that specifies which amino acid will be added to the growing protein during translationl. Since a codon is found in DNA and RNA, the NUCLEOTIDE BASESare the molecules that make up codons
If a nucleotide is added or removed from a DNA molecule and mrna is created the codons after the mutation will not be read correctly this is a?
Mutation
What marks the beginning and the ending of a gene on a DNA molecule?
start and stop sequences Also called Star and Stop codons. These are base triplets in the DNA base sequence. Examples of Stop Codons ar TAG or TGA.

What in a gene determines a protein's composition?
A gene is made up of triplets of nucleotides called codons. Each codon translates for a a specific amino acid. Some codons don't translate for an amino acid; they are called stop codons or non-sense codons. When m-RNA transcribes the codon triplets and carry them to t-RNA, each amino acid is assembled by r-RNA in the order speicifed in the gene. Thus, the sequence of the codons in the genes is responsible for the sequence of proteins.
What are anticodons and triplets in replications?
Anticodons: Prest in the tRNA molecule,involved in the protein syntehesis Triplet or codon: Three letter base(eg:AUG-Met) of mRNA, codes for a particular aminoacid. Replication:Duplication of DNA moleculs(codons and anticodons are not relevant with this processs!)
What molecule contains all of the codons needed to produce a particular polypeptide?
A single mRNA molecule has 3 codons i.e. 1 amino acid. The question is flawed and does not make sense!
What is in the genetic code?
Three-base triplets called codons. Each codon will be translated into an amino acid during the process of translation.
Which molecule would you expect to find codons?
Codons are groups of three nucleotides on the mRNA strand. Codons are bound to the ribosomes where they are met by tRNA's anticodons. Together, the codons and anticodons form amino acids which bind together via peptide bonds and form amino acid chains known as polypeptides or proteins. These proteins are released into the cell to perform their desired functions.
In relation to protein what is called for when DNA bases are combined in different triplets?
When DNA bases are combined into different 3-base codes, called triplets or codons, different amino acids are called for to create the protein chain.
What is the name for the 3-based words written in DNA and RNA?
In DNA, three bases in a row are known as triplets. In RNA, they are known as codons.
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 natural occurring amino acids does the genetic code allow for?
There are 64 possible triplets. At least one of the triplets needs to be a stop codon, so theoretically 63 different amino acids can be coded for. In practice, there's some redundancy, and in humans all codons are either stop codons or translate to one of twenty amino acids.
Which molecule contains protein building instructions?
DNA
