Voet 980 solutions What are sections of an mRNA molecule that are removed?Most pre-mRNA molecules have sections that are removed from the molecule, called introns, and sections that are linked or together to make the final mRNA, called exons. This process is called splicing.
What is removed from an mRNA Strand before it is complete?At this point, at least in eukaryotes, the newly synthesized mRNA undergoes a process in which noncoding nucleotide sequences, called introns, are clipped out of the mRNA strand. This process "tidies up" the molecule and removes nucleotides that are not involved in protein production (Figure 6).
How many nucleotides long is mRNA?It was also known that there are only four nucleotides in mRNA: adenine (A), uracil (U), guanine (G), and cytosine (C).
Which end of mRNA is translated first?In this situation, translation begins at the 5' end of the mRNA while the 3' end is still attached to DNA. In all types of cells, the ribosome is composed of two subunits: the large (50S) subunit and the small (30S) subunit (S, for svedberg unit, is a measure of sedimentation velocity and, therefore, mass).

Is a portion of mrna that is about 1,000 nucleotides long and that is removed before translation.
