Question 2: Transcription, RNA Processing and Translation A particular gene codes for a mature mRNA transcript containing 1200 bases, which is translated into a protein containing 300 amino acids. A. How long is the coding sequence in this mRNA and how many nucleotides are in the UTRs? For the purposes of this question we are ignoring the G’ cap and the polyA tail. B. A mutant form of the gene created by one nucleotide being changed to another nucleotide also...

QUESTION 7 Consider the hypothetical gene show here. The gene coding sequence consists of 4 exons (shown in solid colors). The 5' UTR and 3' UTR are shown as striped boxes. 25 150 200 300 400 25 Based on the lengths of the exons, you should be able to calculate a rough estimate of the protein encoded by this gene, assuming that all 4 exons are translated and the protein does not undergo any significant processing (cleavage or chemical modifications)....

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...

Protein Structure A protein contains a string of amino acids (usually more than 50) that has a biological function. 15ecause proteins are so large, their structure has several levels, all of which are important for the proper functioning of the protein. Ultimately, the sequence of amino acids (ordering of polar and nonpolar amino acids) dictates the 3-dimensional shape of a protein and this dictates its primary function.
