Which one of the following statements correctly describes the synthesis
of mammalian messenger RNA (mRNA)?
a. Each mRNA often encodes several different proteins
b. Several different genes may produce identical mRNA molecules
c. There is colinearity of the RNA sequence transcribed from a gene and the amino
acid sequence of its encoded protein
d. The RNA sequence transcribed from a gene is virtually identical to the mRNA
that exits from nucleus to cytoplasm

e. Mammalian mRNA undergoes minimal modification during its maturation

a. Each mRNA often encodes several different proteins = NO
b. Several different genes may produce identical mRNA molecules = NO
c. There is colinearity of the RNA sequence transcribed from a gene and the amino acid sequence of its encoded protein = I guess so! :)):))
d. The RNA sequence transcribed from a gene is virtually identical to the mRNA that exits from nucleus to cytoplasm = NO
e. Mammalian mRNA undergoes minimal modification during its maturation = NO

The answer is( b )according to pre test series however i feel it should be( a )as in eukaryotes the mRNA are monocistronic not polycistronic.Please comment and explain !:notsure:
