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.
Can a codon contain two of the same nucleotide bases?
no
The genetic code is said to be universal because a codon represents the same?
The genetic code is said to be universal because a codon representsthe same amino acid in almost all organisms.
The genetic code is degenerate?
Each amino acid can be specified by more than one codon.
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 is the initiator codon in most molecule of mRNA?
AUG
Where is the initiator tRNA first attached to the mRNA?
The initiator tRNA is first attached at the start codon (AUG) on the mRNA. The anticodon of the initiator tRNA base pairs with the start codon, signaling the beginning of translation.
Translation begins when the initiator tRNA binds to the?
start codon on the mRNA strand. This signals the ribosome to begin assembling the amino acid sequence based on the mRNA instructions.
Where does initiation of translation occur?
An initiation complex for translation forms by the assembly of the ribosomal subunits and initiator tRNA (met-tRNA) at the start codon on the mRNA.
What is the step of translation in which an mRNA a small ribosomal subunit and the initiator tRNA are aligned together is?
The step of translation in which an mRNA, a small ribosomal subunit, and the initiator tRNA are aligned together is called initiation. This process occurs with the formation of the initiation complex, where the mRNA binds to the small ribosomal subunit and the initiator tRNA carrying methionine binds to the start codon on the mRNA.
What describes the initiation step of translation?
The initiation step of translation begins when the small ribosomal subunit binds to the mRNA at the start codon, typically AUG. The initiator tRNA, carrying the amino acid methionine, pairs with this start codon. This assembly is facilitated by various initiation factors, which help stabilize the ribosome and ensure proper alignment. Once the initiator tRNA is in place, the large ribosomal subunit joins to form a complete ribosome, ready for elongation.
What codon serves as the start codon for protein synthesis?
AUGMethionine is specified by the codon AUG, which is also known as the start codon. Consequently, methionine is the first amino acid to dock in the ribosome during the synthesis of proteins.
What happens after the ribosome reaches the start codon?
When a ribsome reaches a stop codon, the translation process stops and a protein is released.
What is the meaning of MI in tau gamma phi?
Master Initiator.
What is the initiator codon in most molecules of mRNA What is its function What are the stop codons What is their function?
The initiator codon in most molecules of mRNA is AUG, which codes for the amino acid methionine and signals the start of protein synthesis. Its function is to establish the reading frame for translation and initiate the assembly of the ribosome at the correct site. Stop codons—UAA, UAG, and UGA—do not code for any amino acids and signal the termination of protein synthesis. Their function is to indicate to the ribosome that the polypeptide chain is complete, prompting the release of the newly synthesized protein.
What is initiator in Tagalog?
Tagalog translation of INITIATOR: pasimuno
What is the start codon and what amino acid does it code for?
AUG. The amino acid methionine. Bases read; adenine-uracil-guanine
