2. Write out the RNA transcript. 3. In as much detail as you can ( the polypeptide. more is better here) explain how the RNA transcript is translated into 4. Explain to me what would h appen if the polypeptide had a signal recognition particle near the beginning? 5. Assume the template strand GGC in wild type cDNA that amino acid Asp is inserted explanation for how this occurred and what name is given to th nucleotide sequence for the Gly amino acid at position number 4 reads is transcribed into mRNA. When this nucleotide sequence is translated the into position number 4 in the polypeptide chain. Provide a possible is? 6. If the mRNA transcript for the amino acid at position number 7 in the polypeptide chain was changed from UAU to UAC what effect would this have and what is this result called? 7. If the amino acid Gly at position number 4 had the nucleotide cytosine in the 3rd position of the codon replaced with a guanine nucleotide what would the effect be and what is this effect called? 8. Write out the names of each amino acid in the polypeptide shown below.

Explanation / Answer

GGC in cDNA codes for Gly amino acid at position 4. Asp inserted at position 4 means, it would perhaps be the codon GAC. That means. the second nucleotide of GGC is substituted by A. So, that form Asp amino acid.

This is a type of point mutation (base substitution).
