How many codons are present on the mRNA strand?
There are 6 codon here. Look at the letters and put them into threes. Those three are called codons. Each codes for one amino acid and all of these is a string of threes which will make a small protein.
A protein contains 131 amino acids How many bases will there be on the mRNA strand corresponding to these amino acids and how do you know?
131*3=393 bases might be there on mRNA strand 3 codons of mRNA strand deduce an aminoacid of a protein, so here, mRNA strand bases are being asked.
Do you use mrna codons or trna anticodons for coding chart to tell us what amino acids are coded in dna coding strand?
You use the mRNA. ;)
Where does the process of translation do in mRNA?
The newly spliced mRNA binds to a ribosome. tRNA molecules migrate towards the ribosome, these tRNA molecules carries a specific amino acid. The ribosome allows two tRNA molecules into the ribosome at a time. The tRNA molecules have complementary anti-codons to the codons present on the mRNA strand. Two tRNA move into the ribosome and their anti-codons join to complementary codons on the mRNA strand. As one molecule leaves the ribosome, its amino acid forms a peptide bond with an amino acid on the adjacent tRNA molecule, with the help of ATP and an enzyme. As the ribosome moves along the the mRNA strand, a polypeptide chain is created. The ribosome stops reading the mRNA strand when it reaches a stop codon.
If the base sequence of template strand is GCCATTAC what would the base sequence of the mRNA?
The mRNA will have codons AUG-CCA-GUA-GGC-CAC
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.
If there are 1200 nucleotides in DNA strand how may codons will be in mRNA strand?
400 codons.Because 3 consecutive nucleotides in a gene together form a codon which codes for amino acids.
What is rRNA polymerase?
it decodes the mRNA to then the codons of the mRNA can interact with the anti-codons of the tRNA
Are there three bases on the mRNA called codons?
All mRNA and DNA sets of three are codons, and rRNA is anti-codons.
What happeneds in synthesis?
First, the DNA polymerase makes a copy of the DNA. The nucleotides then bond together and form a complete mRNA strand. The mRNA strand travels out to the cytoplasm through the nucleus. The mRNA is then met by a ribosome and tRNA. Codons and amino acids are then created. After the tRNA detaches from the mRNA strand, the amino acids are connected by a polypeptide bond. This results in a protein. So basically... Protein synthesis is going from DNA to mRNA to tRNA to a protein.
On what structure is the codon found?
A codon consists out of a 3 nucleotid long DNA piece. That 3 nucleotids code for an amino acid.
Which type of RNA contains the codon?
Messenger RNA, or mRNA contains the codons. tRNA (transfer RNA) contains the anti-codons which bond to the codons of the mRNA. Amino acids are attached to the tRNA and form polypeptides based on the codons on the mRNA.
