Homework Answers
1st one is absolutely correct answer because 3 nucleotides form one codon and code for one amino acid.
Example-AUG code for methionine.

Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...

O a ER bound ribosome signal peptide on the N terminus of the polypeptide chaperone protein signal peptide on the C terminus of the polypeptide O signal-recognition particles A tRNA is chemically modified so that the amino acid bound is different than the one specified by its anticodon. Which codon in the mRNA would the tRNA recognize: the one...

Transfer RNA molecules are short RNA sequences (on average around 78 nucleotides long) that form a stem-and-loop structure, where one of the loops carries the anticodon that binds with the appropriate codon in the messenger RNA. At least 30 different tRNA genes are required by each cell to specify translation, but each of these tRNA genes can occur in multiple copies in a single genome, often co-located in clusters. How might these features of tRNA structure and function influence the...

Problem 7 A) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first two nucleotides of the codon? B) In how many cases would you fail to know the first two nucleotides of the codon if you knew which amino acid is specified by it?
There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein
There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein. During protein synthesis, the job of a tRNA molecule is to carry its particular amino acid to the growing protein chain and find the correct amino acid position there. It does this by matching a 3- letter anticodon on the tRNA to a complementary 3-letter codon on mRNA. Below, in a diagram of a ERNA molecule, nucleotides are represented by small circles, some...

The six nucleotides preceding the start codon and the first nucleotide after the start codon in eukaryotes exhibit strong sequence preference as determined by the percentages of nucleotides in the -6 to -1 positions and the +4 position. Use the data given in the table to determine the six nucleotides that most commonly precede the start in vertebrates. Express your answer as a sequence of nucleotides separated by dashes. Example: 5'-C-A-T-G-...-3' Use the data given in the table to determine...
