The schematic illustrates steps in RNA processing. The DNA
strand is shown in red and yellow, and the RNA strand is shown in
green and blue. The steps in RNA processing are labeled 1-3, and
the components of the RNA transcript are labeled A-C.
Steps in RNA processing are indicated below in alphabetical order, select the step number to put these processes in chronological order. If the indicated step does not occur, select 'This process does not happen'.

Eukaryotic messenger RNA undergoes several processing steps after transcription before it binds to ribosomes as the template for protein synthesis. One of these steps is polyadenylation. Identify whether the statements below about polyadenylation are true or false. A polymerase adds a polyadenylate tail of about 10 nucleotides to the 3' end of the mRNA. A polymerase adds a polyadenylate tail to the mRNA while it is still in the nucleus. The polymerase forming the polyadenylate tail uses a polydT DNA...

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...

Hemoglobin is a protein that is found in red blood cells. It binds to oxygen in the lungs and it carries it to tissues and cells throughout the body. Hemoglobin is made of four polypeptide chains, two called “alpha-globins” (a) and two “beta-globins" (B). The B-globin polypeptide is produced in the cells based on the sequence of the HBB gene. The structure of the HBB gene that codes for beta-globin is represented below. The primary transcript is 1606 nucleotides long....
