3. If an mRNA has 4 exons, how many different combinations of exons could be made if EXON 1 must be kept?
b. How many different proteins could be made from the information above?
3. 1,2,3,4
If 1 is kept and one exon is removed at a time then 2 combinations of exons could form-
1,3,4
1,2,3
b. two different proteins could be formed from these two combinations.

A geneticist discovers that two different proteins are encoded by the same gene. One protein has 56 amino acids, and the other has 82 amino acids. Which of the statements are possible explanations for how the same gene can encode both of these proteins? 1-The same gene encodes both proteins by using different combinations of introns in the pre‑mRNA via alternative splicing. 2-The same gene encodes both proteins by generating a poly(A) tail on the pre‑mRNA. 3-The same gene encodes...
The following mRNA sequence is taken from the middle of
exon 3 in a mature mRNA that has many exons, and the mRNA encode 9
amino acids.
Question: Knowing that this mRNA does not have an early
stop codon, which of the reading frames shown is the correct one
for this mRNA? Write down 1, 2, or 3 as your answer. Explain
why?

OLU Ucues Assignment 4c. In eukaryotes, genes are composed of exons and introns, with only exons included in the mRNA. Each gene also has its own adjacent promoter, to which the transcribing enzyme RNA polymerase binds. Related genes may be clustered together on the same chromosome as a “gene family." Answer each of the following questions in the answer box of the assignment. You may also write the answers directly into the assignment document and then upload your answers. Number...
A eukaryotic protein-encoding gene has three introns and 4 exons. A splicing repressor commonly binds to the 3' end of the second intron (introns 2/ exon three splice sites) draw the mRNA strand before and after splicing Diagram a final functional eukaryotic mRNA molecule from the 5' end to 3' end. There should be 7 items labeled in the diagram.

4. Here is an RNA transcript freshly transcribed from a gene. It is immature, meaning that it has not been processed yet into a mature mRNA. a) If you could zoom in on this molecule, what two things would you observe at the molecular level that would indicate to you that it is RNA and not DNA? b) Which end of the molecule was the last bit to be transcribed,...
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...
