Introduction: During RNA processing, alternate splicing of pre-mRNA produces different mRNA variants from a single gene. This results in synthesis of multiple isoforms of protein encoded by a single gene. In this, certain exons may be included or excluded from the mature mRNA.
B.
To determine: The accuracy of the statement, “alternate exons ‘2 and, 3’ in human α-tropomyosin gene must each contain an integral number of codons (that is, the number of nucleotides divided by 3 must be an integer)”.
Introduction: During RNA processing, alternate splicing of pre-mRNA produces different mRNA variants from a single gene. This results in synthesis of multiple isoforms of protein encoded by a single gene. In this, certain exons may be included or excluded from the mature mRNA.
C.
To determine: The accuracy of the statement, “alternate exons ‘2 and, 3’ in human α-tropomyosin gene must each contain a number of nucleotides that when divided by 3 leaves the same remainder (that is, 0, 1, or 2)”.
