Hetero Nuclear RNA or hnRNA is the unmodified transcript. What process cuts out pieces of this RNA molecule? What is the name of the regions that are cut out?
The figure below shows the introns and exons found in gene X. The size of each exon and intron is shown as well. A study on this organism found that two mature mRNA molecules are produced for this gene. One is 457 nucleotides in length, and the other is 439 nucleotides in length. Name the process responsible for producing this variation. Also explain how these 457 and 439 nucleotide fragments were produced by referring to the information provided. Hint: This organism produces a poly-A tail of 120 nucleotides.

What fraction of the average protein-coding gene is converted into mRNA? What fraction of the chromosome do these genes occupy?arrow_forwardThe following double stranded segment of DNA is part of a protein coding gene. The segments in uppercase letters (ACTG) represent the exons. The segments in lowercase letters (acgt) represent introns. The lower strand is the template strand that is used by the RNA polymerase to make an RNA transcript. Draw or write-out a) the sequence of the primary transcript and b) the mature mRNA resulting from this stretch of DNA.arrow_forward
- After the intron (which is in a lariat configuration) is released during pre-mRNA splicing, a brief moment occurs before the two exons are connected to each other. Which snRNP(s) hold(s) the exons in place so they can be covalently connected to each other?arrow_forwardMetabolic syndrome is a genetic disorder with symptoms of hypertension, elevated blood cholesterol concentrations, and lower-than-normal blood magnesium concentrations. This syndrome is caused by a mutation in mitochondrial DNA (mtDNA) in which a thymine nucleotide is replaced by a cytosine nucleotide. Which of the following identifies the mutated mtDNA and the corresponding mRNA and tRNA produced in a person with metabolic syndrome if the normal mtDNA triplet is TCG? Select one: a. Mutated mtDNA: CCG mRNA: GGC tRNA: GGC b. Mutated mtDNA: TCG mRNA: UGC tRNA: ACG c. Mutated mtDNA: CCG mRNA: GGC tRNA: CCG d. Mutated mtDNA: TTG mRNA: AAC tRNA: UUCarrow_forwardHemophilia in the Russian royal family was caused by defective protein involved in blood clotting (factor IX). This defective protein was caused by a mutation that altered the splicing of the exons. This genetic change in the splicing pattern created a new stop codon in the mRNA for factor IX. Is it likely that the mutation has altered at least one base at the exon-intron boundary in the wild-type pre-mRNA? Why or why not?arrow_forward
- "The gene for Receptor Z contains an unknown number of untranslated first exons that are spliced to a common exon 2" - what does it mean if a "first exon" is "spliced to a common exon 2"? Does it mean that Exon 1 is attached to Exon 2, but Exon 1 is not part of the translated protein - similar to the below schematic? mRNA Option 1: [Exon 1a][Exon 2][Exon 3].... mRNA Option 2:[Exon1b][Exon2][Exon 3] mRNA Option 3: [Exon1c][Exon2][Exon 3]arrow_forwardHere is a eukaryotic gene. The numbers given are base pairs of exon and intron. How long in bases will the pre mRNA transcript be? Explain briefly.

- A normal hemoglobin protein has a glutamic acid at position 6; in sickle-cell hemoglobin, this glutamic acid has been replaced by a valine. List all the possible mRNA codons that could be present for each type of hemoglobin. Can a single base change result in a change from Glu to Val in hemoglobin?arrow_forwardAccording to the Central Dogma, genes are the blueprints for making proteins. Each gene (humans have 21,325) contains a single “coded message” of DNA bases (A, T, G, & C) attached in a specific order, which the cell “reads” to create an mRNA molecule that is then translated into protein. Knowing this, EXPLAIN how a SINGLE gene can make different proteins in different cells.arrow_forwardA eukaryotic protein-encoding gene contains two introns and three exons: exon 1–intron 1–exon 2–intron 2–exon 3. The 5′ splice site at the boundary between exon 2 and intron 2 has been eliminated by a small deletion in the gene. Describe how the pre-mRNA encoded by this mutant gene will be spliced. Indicate which introns and exons will be found in the mRNA after splicing occurs.arrow_forward
