3. D. 4. False if you inspect the genetic code, you can see that some amino acids can have multiple different mRNA codons. It is possible to get a mutation that will create an mRNA codon that will bring in the SAME amino acid as the original.5.. One codon of an mRNA reads GUA, which specifies valine. If a mutation changes the first nucleotide of the DNA coding for this RNA to an A, use the genetic code to determine what amino acid will be put in after the mutation.

A Rolodex is a rotating file device used to store business contact information (the name is a portmanteau word of rolling and index) with classic replicas manufactured by Newell Rubbermaid. The Rolodex holds specially shaped index cards; the user writes or types the contact information for one person or company onto each card. The cards are notched to be able to be snapped in and out of the rotating spindle. Some users tape the contact's business card directly to the Rolodex index card, or a plastic or vinyl sleeve in the shape of a Rolodex card to place the business card within. Some companies produced business cards in the shape of Rolodex cards, as a marketing idea.
