please identify structure information about this gene which is adgrg1/gpr56. You can identify anything about the molecule including chains, atoms, etc.
What sequence is shown in Figure 1? Label all 5' and 3' ends.
You have the following DNA coding sequence of a wild-type allele:
5’-ATG TTC CAG CTA GAT GAT ATG CTG GTA ATT GGG GAA CGC GCG CGG TAA-3’
For each of the following mutations:
A. State whether the mutation is missense, nonsense, frameshift, or silent.
B. Write the codon change that occurs for the missense, nonsense, and silent mutations (ex. GAA -- GAT).
C. For frameshift mutations, write out the entire mutant sequence with each codon clearly indicated (if the frameshift creates a new stop codon, end the sequence at the new stop).
Using the wild type DNA sequence above as a guide :
Write the amino acid sequence of the mutants.
Mutant 1: transition at nucleotide 23
Mutant 2: T --> G transversion at nucleotide 29
Mutant 3: an insertion of “A” after nucleotide 14
Mutant 4: transition at nucleotide 7
Mutant 5: An insertion of GG after nucleotide 40
Mutant 6: transition at nucleotide 15
Mutant 7: a deletion of nucleotide 25
