You found a mutation in a gene that causes a reading frame shift early in its mRNA. This introduces an early stop codon that results in a complete lack of functional protein. Which of the following is the most likely cause of this mutation? A single base deletion in an exon of the gene A 6 base deletion in an intron the gene A 3 base insertion in an exon of the gene A 4 base insertion in an intron of the gene

Give only typing answer with explanation and conclusion Recombinant human insulin produced by bacteria carrying a cloned insulin gene, is now the major form of insulin used to treat diabetes. The human insulin gene encodes an mRNA only 333 nucleotides long, but the entire gene spans more than 4000 nucleotides. There are three exons and two introns 1. Every cell in the human body has the same DNA, so very cell has an insulin gene. However in order to use the technique, you described in b, you would have to start with cells from the pancreas the only body cells that actually produce the insulin protein. Why are these the only cells that would work.

Refer to a genetic code table for the question. below is a portion of the template strand of a particular gene sequence. Which of the following would be the correct sequence of amino acids in the protein that this portion of the gene encodes? (Note that there are no entrance in this gene sequence, and this portion is found in the middle of the coding sequence, past the start codon, so you should transcribe and translate the entire portion of this sequence) template DNA : 3' - ACG GGT TCC TTT AAC GCG TAG -5' A) Thr-Gly-Ser-Phe-Asn-Ala B) Cys-Pro-Arg-Lys-Leu-Arg-Ile C) there is not enough information given to determine the amino acid sequence of this portion of the gene .
