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'.

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....
