An RNA molecule has the following sequence: ’UCAAUGCUUAAGAAGGCAUGAAAUAA 3’ Label the protein-coding region of this mRNA, and any other region(s) that are
present. What is the sequence of the polypeptide it codes for?
The start codon, protein coding region and stop codon are marked below:
the sequence of the polypeptide it codes for is :
AUG - methionine
CUU - leucine

AAG - lysine
GCA - alanine
Which can also be written as - methionine - leucine - lysine - lysine - alanine
OR
met—leu-lys-lys-ala

2. When transcribing an mRNA strand, RNA polymerase uses the strand of DNA to match complementary bases with. RNA polymerase always reads this strand in the direction and always builds mRNA in the direction. (1.5 pts) 3. (0.5 pt) What is the significance of the +1 site in regards to transcription of mRNA? t) When translating an mRNA sequence, where does the ribosome always begin? 5. (0.5 pt) When translating an mRNA sequence, what signals the ribosome to end translation?...
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...
