Oxytocin is a small peptide hormone.
It contains a nine amino acid sequence shown below:
CYIQNCPLG
33
How many nucleotides would be found in the mRNA for this protein?
Suggest an mRNA sequence for the peptide. Write in as 5' XXX 3' (no spaces between nucleotides). Keep
in mind, for a protein to be synthesized it needs to include a start codon and a stop codon.
Suggest a complementary template DNA sequence based on the MRNA sequences suggested above.
Write in as 3' XXX 5' (no spaces between nucleotides).

Which of the following statements regarding the structure and function of tRNA is true?
A-The codon / anticodon pairing is absolutely universal among organism.
B-The charging of a tRNA does not require energy.
C-There are 64 different tRNAs, one for each possible codon.
D-Reading 5' to 3', the first base in the anticodon can participate in non Watson and Crick base pairing
E- The 3' end of each tRNA has a unique sequence so a specific amino acid can be attached.
The sequence below shows the non-coding strand from the
whole of the transcribed region of a very short gene.
5’-GGCTTCTTTAGTACTGGCCAGTGGGATCCAAGTAGGCTGCCATTTCGT-3’
Write out the sequence of the mRNA from this gene in the orientation 5′ → 3′ and, using the genetic code (see Fig. 1. overleaf) deduce the amino acid sequence of the peptide it encodes (NB you should read about the operation of the genetic code prior to attempting this question).

- 2a) In prokaryotes, a small ribosomal subunit can potentially get on an mRNA anywhere it can find enough space to do so. Once a small ribosomal subunit has bound to an mRNA, it will scan along that mRNA in the 5' to 3' direction looking for a start codon at which to initiate translation. How does the small ribosomal subunit distinguish a start codon from any other AUG codon that simply codes for methionine in the middle of a coding sequence?arrow_forwardFigure 3 represents one process that occurs during protein synthesis. amino acid molecule Q A UGC C GỤ AC C GAC Ų (a) Name the process shown.
