Question

Exercise 4. Translatio n is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes. In the cell cytoplasm, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein. Fill in the blanks: Genetic code of triplets of bases are present on Anti-codons of triplets of bases are present on Procedure Ste p 1: Place on the ribosome in the cytoplasm. This will be the site of protein synthesis. Step 2.Construct the tRNA molecules by matching three bases that are complimentary to the bases of a codon on the mRNA. Step 3: Find the amino acids with the specific R- groups that matches each tRNA. Step 4: Attach the tRNAs to the R-groups of their specific amino acids. Step 5: Bring the tRNA-amino acid complex to the codon of mRNA which codes for that tRNA. Attach the hydrogen bonds. Step 6: Attach covalent (peptide) bonds (grey tubes) between adjoining amino acids. These peptide bonds are formed through a series of dehydration reactions. Step 7: Disconnect the polypeptide (amino acid chain) from the tRNAs. The polypeptide chain will then coil or fold 20
