| Question | Answer |
|---|---|
| Full name for RNA | ribonucleic acid |
| RNA sugar | Ribose |
| Base that belongs to RNA only | Uracil |
| Three types of RNA | mRNA = messenger RNA rRNA = ribosomal RNA tRNA = transfer RNA |
| Function/Definition of mRNA | type of RNA that carries copies of instructions for the assembly of amino acids into proteins from DNA in the nucleus to the cytoplasm |
| Function/Definition of rRNA | type ofnRNA that combines with proteins to form ribosomes |
| Function/Definition of tRNA | type of RNA that carries each amino acid to a ribosome during protein synthesis has anticodon and amino acid attached to the tRNA |
| transcription | synthesis of an RNA molecule from a DNA template or process of copying a base sequence from DNA to RNA or DNA makes RNA through the process of transcription |
| RNA polymerase | enzyme that links together the growing chain of RNA nucleotides during transcription, using a DNA strand as a template |
| DNA makes _________ makes _____________ | DNA makes RNA makes Proteins |
| mutation that shifts the “reading frame” of the genetic message by inserting or deleting a nucleotide | frameshift mutation |
| long chain of amino acids joined together by peptide bonds that make proteins | polypeptide |
| collection of codons of mRNA, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis | genetic code |
| group of three nucleotide bases in mRNA that specify a particular amino acid to be incorporated onto a protein | codon |
| process by which the sequence of bases of an mRNA is converted into the sequence of amino acids of a protein | translation |
| group of three bases on a tRNA molecule that are complementary to the three bases of a codon of mRNA | anticodon |
| change in the genetic material of a cell | mutation |
| gene mutation in which a single base pair in DNA has been changed | point mutation |
| mutation that shifts the “reading frame” of the genetic message by inserting or deleting a nucleotide | frameshift mutation |
| chemical or physical agent in the environment that interacts with DNA and may cause a mutation | mutagen |
| condition in which an organism has extra sets of chromosomes | polyploidy |
