A diagram of a gene is shown below. Normally, exons 1, 2, and 3 are present in the mature mRNA. (shown in attatched image)

A mutation occurred at the 5’ splice site of exon 1 as shown by the star such that the spliceosome cannot bind to this location during mRNA processing of the pre-mRNA into the mature mRNA. Which of the following is/are a possible result of this mutation? (select all that apply)

a)The pre-mRNA transcribed from this gene sequence will be longer than normal.

b)The protein translated from this mRNA will be a different length than the normal protein.

c)The mature mRNA will be longer.

d)The mature mRNA will be shorter.
