Consider the following DNA sequence, which codes for a short polypeptide: 5'-ATGGGCTTAGCGTAGGTTAGT-3' Determine the mRNA transcript of this sequence. You have to write these sequences from the 5' end to the 3' end and indicate those ends as shown in the original sequence in order to get the full mark. How many amino acids will make up this polypeptide? Determine the first four anticodons that will be used in order to translate this sequence.
Suppose that the diagram below represents the genomic organization of an enzyme involved in eye pigment production in mice. Within the gene are four exons. Biochemical analysis has revealed that the active site of the enzyme is located in the C terminus of the protein. -The nucleotide length of each exon and intron is shown. -The dinucleotide sequence GT represents the 5’ splice site and the dinucleotide sequence AG represents the 3’ splice site. Both the 5’ and the 3’ splice sites must be present for splicing to occur. Assume that the first and second stop codons are located immediately after the first and second 5’ splice sites, respectively; the third and fourth stop codons are located near the 3’ end of exons 3 and 4, respectively; all these stop codons are in the correct reading frame. a) draw what the processed mRNA will look like. Include the start codon on the mRNA and label the approximate locations of the 5’ UTR and 3’ UTR on the transcript. (You do not need to add the 5’ CAP…
Give typing answer with explanation and conclusion Which description applies to alternative mRNA splicing? 1. heritable changes in gene expression that occur without altering the DNA sequence 2. processing of exons in mRNA that results in a single gene coding for multiple proteins 3. mRNA modifications such as additions of a 5′‑cap and 3′ poly‑A tail and removal of introns 4. a gene cluster controlled by a single promoter that transcribes to a single mRNA strand 5. protein modifications such as addition of a functional group or structural changes such as folding Answer 2 is correct.
Create a Venn diagram to compare and contrast the process of gene expression in Bacteria versus eukaryotes. Remember that “gene expression” can include any part of transcription or translation. Try to be as thorough as you can about what aspects of this process are similar between the two taxa, and what characteristics are distinct to only Bacteria or eukaryotes. Plase include a minimum of 15 items in the Venn diagram.
Complete the protein synthesis for the partial DNA sequence for a normal FGFR3 gene (TOP) and mutated FGFR3 gene (BOTTOM). Remember, when filling in mRNA, use capital letters only. When filling in amino acids, use three letters, with the first letter capitalized. If you do not use this format, your answer may be marked wrong.

The amino terminus of a wildtype enzyme in yeast has the amino acid sequence Met-Leu-His-Tyr-Met-Gly-Asp-Tyr-Pro A mutant, X, is found that contains an inactive form of the enzyme with the sequence 4 CO G Search or type URL X 4 | 7 | - 125% + | @ Met-Gly-Asp-Tyr-Pro at the amino terminus and a wildtype sequence at the carboxyl terminus. A second mutant, Y, also lacks enzyme activity, but a full-length protein is not observed. Instead, mutant Y makes a short peptide containing just 3 amino acids. What mutations could account for these changes in mutant X and mutant Y? As part of your answer, show the sequences of the genes encoding the wildtype proteins and the 2 mutant proteins, and indicate in the wild type sequence where the mutations that gave rise to X and Y actually occurred.
