You are presented with the following DNA molecule: 5’ A T G C G A T T A T A A 3’ 3’ T A C G C T A A T A T T 5’ A. Write the template DNA strand B. Transcribe the template DNA strand into mRNA C. Translate the mRNA into an amino acid sequence

You are working in the lab and have measured the size of mRNA that has been transcribed from a particular gene in your cell population. The length of the gene in the cells you are working, measured from the start to the stop sequence is 9000 nucleotides. When you measure the RNA, however, the size is only 3000 nucleotides. What do you think happened? O a. Three DNA base pairs code for one RNA nucleotide. b. mRNA does not contain exons. c. There must have been a deletion mutation in the DNA in these cells. Od. The poly-A tail is present in the DNA but not on the mRNA. Oe. RNA splicing occurred, so introns are removed in the mRNA.

a. The reading frame DNA sequence is b. The mRNA sequence is c. The polypeptide sequence is a.The mutated polypeptide sequence is b.What kind of mutation was produced?
