Dna Mutations
What is the central dogma of molecular biology? DNA - RNA - Protein RNA - Protein - DNA DNA - Protein - RNA RNA - DNA - Protein What was the first type of mutation explained in the video? frameshift point nonsense silent What is the RNA strand of the mutated sequence used during the explanation of a point mutation? CTCCTCCTC GAGGAGGAG CTCCTCCAC GAGGAGGUG Where did the frameshift mutation occur? Between base 1 2 Between base 2 3 Between base 3 4 Between base 4 5 Between base 5 6 Between base 6 7 What type of mutation occurred during the first frameshift explanation? insertion deletion What type of gene mutation? Point usually only affects 1 amino acid Frameshift entire amino acid sequence can be changed insertion or deletion of a single gene or nucleotide base Sickle-cell disease is an example of what type of mutation? somatic frameshift point nonsense Using the video, fill in the blanks. Mutations originate at the DNA level, but show their effects at the protein level. Mutations can be classified by neither their effects on DNA or on protein.
