They do this by alternative splicing (AS). Alternative splicing means, that during the RNA splicing event different combinations of exons can be joined together to create a diverse array of mRNAs from a single pre-mRNA. When these are translated they produce different proteins which do different things.
DNA double helix unwinds, and the bases on the two. strands are exposed. RNA nucleotides. (ribonucleotides) line up in the proper order by. hydrogen -bonding to their complementary bases on. DNA, the nucleotides are joined together by a DNA. dependent RNA polymerase enzyme , and a piece of. mRNA is produced. â¢ UNLIKE what happens in DNA replication where both. strands are copied, only ONE of the two DNA strands. is transcribed into mRNA (remember that RNA is a. single-stranded molecule).
