1. Part of the mRNA sequence of an exon (coding region) of a gene that encodes a blood protein is:
AUG ACU CAU CGC UGU AGU UUA CGA
Consult the genetic code to answer the following questions:
a. What is the sequence of amino acids that this mRNA encodes?
b. What is the sequence if a point mutation changes the tenth base from a C to an A?
c. What is the effect of a point mutation that changes the fifteenth base from a U to an A?
d. How does the encoded amino acid sequence change if a C is inserted between the fourth and the fifth base?
e. Which would be more devastating to the encoded amino acid sequence, insertion of three bases in a raw, or insertion of two bases in a row?
