6. Draw and label a typical gene including the following:
a. 5’ and 3’ ends
b. core and proximal promoters
c. protein coding region
d. 5’ and 3’ UTR
e. 2 Introns and 3 exons
Homework Answers
Non coding DNA is found within most eukaryotic genes. such geens
have a split struture in which segments of coding sequence (exons)
are seperated by non coding sequences(introns) the entire gene is
trancribed to yield a long RNA molecule and the introns are then
removed by splicing, so only exons are included in the mRNA. The
process of excising the sequences in RNA that correspond to introns
and joining of sequences corresponding to the exons is called RNA
splicing.

The typical human gene contains an average of 8 exons. The exons average about 145 nucleotides in length, and the internal introns are usually about 10x that size. Using these values, calculate the following. Please show your work so that partial credit can be given when applicable. a.(5 points) Assuming only internal introns, a 100 nucleotide 5’ untranslated region, and a 800 nucleotide 3’ untranslated region, how long is the typical pre-mRNA in humans? b.(5 points) Assuming complete and perfect...

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...

A gene has 3 exons and 2 introns. While analyzing a mutant, you discover that 9 basepairs are inserted in the middle of intron 1 of this gene. What is the effect of this insertion on the protein? Select one: a. this insertion will have no effect on the protein b. The protein is likely non-functional because the insertion caused a frameshift c. The protein has 3 extra amino acids d. the transcription will be terminated e. the type of...
