What else can I help you with?
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
What are the mrna triplet?
mRNA triplets are three-nucleotide sequences in mRNA that code for specific amino acids during protein synthesis. These triplets, called codons, are recognized by tRNA molecules carrying the corresponding amino acids, allowing for accurate translation of the genetic code into proteins.
What determines where on the DNA molecule transcription begins and where it ends?
I think you are referring to translation - translation is the process of replicating the DNA sequence in order to produce a code for the production of a particular protein, known as an mRNA strand. This code is read in sequences of three bases known as codons. The beginning and end of the mRNA strand is determined by start and stop codons. Start codons, unlike stop codons, also need nearby sequences and initiation factors in order to begin translation. Start codons include base sequences of usually AUG or possibly GUG or UUG depending on the organism. There are three stop codons and these are UAG, UGA and UAA
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
How many codons are in 150 amino acids?
There are 150 codons required to code for 150 amino acids in a protein. Each amino acid is coded for by a specific sequence of three nucleotides (a codon) in the mRNA molecule during protein synthesis.
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.
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
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 is in the genetic code?
Three-base triplets called codons. Each codon will be translated into an amino acid during the process of translation.
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.
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.
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.
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 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!
Does 10 codons result in 30 amino acids?
No, 10 codons do not result in 30 amino acids. Each codon corresponds to a single amino acid, so 10 codons would result in 10 amino acids. The genetic code is read in triplets, where each codon is made up of three nucleotides, but the number of amino acids produced is equal to the number of codons.
What is the connection between base triplets and codes?
Base triplets are the building blocks of codons in DNA. Each base triplet, consisting of three nucleotides, corresponds to a specific amino acid or a stop signal in the genetic code. This relationship between base triplets and codes allows for the translation of DNA sequences into proteins.
