- Suppose a researcher previously cloned gene Y into M13 bacteriophage vector. Gene Y encodes a product called peptide Y. A region of gene Y contains the DNA sequence ATG-CGC-GAA-CTG-GTG-AAC-TAA. The researcher wishes to change a Val residue to an Ala residue in this region of peptide Y using site-directed mutagenesis. What should be the sequence of the mutant oligonucleotide primer in this region? You may use a codon table. mutant oligonucleotide primer sequence: GGC-GGC-GAA-CTG-GTG-AAC-TAA Incorrectarrow_forwardif you have the following sequence of DNA 5' ATTGCGGAGCCTCGAT 3' do the following:arrow_forwardIf an extra nucleotide is inserted in the first exon of the beta globin gene, what effect will it have on the amino acid sequence of the globin polypeptides?

For example, this Histidine has been replaced by the amino acid alanine which has a methyl group (R-CH3) instead of the histidine residue.(a) Would you expect the ability of hemoglobin to bind O2 to be affected by this change?

- The following sequence represents a few codons present in one strand of DNA.Using this strand of DNA as a template strand for transcription, you are required to synthesize a new RNA strand.

- The following double stranded segment of DNA is part of a protein coding gene. The segments in uppercase letters (ACTG) represent the exons. The segments in lowercase letters (acgt) represent introns. The lower strand is the template strand that is used by the RNA polymerase to make an RNA transcript. Draw or write-out a) the sequence of the primary transcript and b) the mature mRNA resulting from this stretch of DNA.arrow_forwardYou want to clone the Human Gene A into a plasmid for producing the Protein A in bacteria. GeneA encodes an mRNA of 100 nucleotides long, but the entire gene spans more than 4000 nucleotides. There are three exons and two introns. If we were to clone this gene directly from the nuclear DNA, bacteria would not be able to express the insulin protein. Explain why this is true.arrow_forwardUsing the transcription unit diagrammed below, in which exons are represented by blue boxes and introns are represented by the connecting lines. You discover a single base deletion in region E of this DNA sequence. Regarding transcription, this mutation will likely: 1.) Result in an alteration to the mRNA sequence. 2.)Have no effect on transcription or the mRNA sequence 3.)Prevent transcription at the TATAA box 4.) Result in an increase or decrease in the amount of mRNA transcribedarrow_forward
