Keep  In the illustration below, “original” (template) DNA polynucleotides are yellow, “new” (copy) DNA polynucleotides are blue.  The 3 DNA molecules in the top row show polynucleotide composition before replication.  The DNA molecules in the bottom row show polynucleotide composition after replication.  Which one of the lettered illustrations correctly shows the semiconservative model of DNA replication?

Keep.  Below are several representations of messenger RNA.  Rather than type out nitrogenous bases I am, representing sequences with the words Intron or Exon to indicate whether that particular segment of mRNA is an intron or an exon.  Which representation shows an mRNA molecule after processing (all steps of mRNA processing have taken place).
