Homework Answers
Answer is middle of the intron.
Explanation:
Because the introns are not found in the mature RNA. Because mRNA undergoes the processing steps. It includes three steps: Capping, tailing and splicing. In the splicing, the introns are removed from the pre-mRNA and the exons are joined together. That's why the presence of genes in the midlle of intron don not affect the protein function.

1. Which of the following mutations is the most likely to be neutral? A) A nonsense mutation in exon 5 of a gene with 39 exons. B) A splice site mutation in intron 3 of a gene with 8 introns and 9 exons. C) A single nucleotide insertion in exon 7 of a gene with 18 exons. D) A thee nucleotide deletion in exon 1 of a gene with 7 exons.

21. One form of thalassemia has a single G->A mutation in the B-globin gene at the first nucleotide in the intron. This destroys the S' splice junction. The mRNA remains unspliced, leaving nucleotide intron in place. Assuming no stop codons are introduced in the intron pro second exon would be in-frame or out of frame in the translated protein dict if the A. In frame B.

QUESTION 6 Assume you are studying a protein-coding gene, ACEX, which includes 4 exons as illustrated in the gene map below. The 5' UTR and 3' UTR segments are each 25 bp long. Exons 1 thru 4 are 100, 200, 300, 400 bp long, respectively. Each intron is 200 bp each. The locations of the relevant EcoRI sites within the ACEX locus are indicated, but the location of other restriction enzyme sites (like BamHI) are not shown." EcoRI probe EcoRI...

TranslationOverview:The purpose of this activity is to help the students to understand how replication, transcription, and translation are connected. Students will use a sequence from a bacterial gene that confers resistance to antibiotics (carbapenems). They will be asked to apply the knowledge obtained in the class lecture to (1) find the promoter in the sequence, (2) determine the amino acid sequence of a fragment of the polypeptide, (3) "reverse translate" a fragment of the polypeptide, and (4) identify mutations in...
