In this unit you will learn the im portance of DNA, RNA and other types

__vocabulary__ > frame shift muations - mutation that shifts the "reading" frame of the genetic message by inserting or deleting a nucleotide > anti-codon - group of three bases on a tRNA molecule that are complementary to an mRNA codon > gene - sequence of DNA that codes for a protein and thus determines a trait > replication - copying process by which a cell duplicates its DNA > codon - three-nucleotide sequence on messenger RNA that codes for a single amino acid > transfer RNA (tRNA) - type of RNA molecule that transfers amino acids to ribosomes during protein synthesis > messenger RNA (mRNA) - RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell > transformation - one stran of bacteria (the harmless strain) is permanently changed into another (disease causing strain) > translation - decoding of mRNA message into a poly-peptide chain
 * 1) mutations - change in a DNA sequence that affects genetic information
