1 A nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a nonsense codon in the transcribed mRNA, and possibly a truncated, and often nonfunctional protein product.
Best Answer: Messenger RNA carries the sequence of nucleotides that code for protein, from the nucleus to the cytoplasm. DNA can't because it is double stranded and can't fit into the nuclear pores, while mRNA is single stranded, uncoiled.eport Abuse. mRNA is the template strand for the production of protein tRNA is the transfer RNA that places the complementary codon (sequence of 3 complementary bases coding for an amino acid) based on the mRNA sequence.
