- 3. Multiple Choice
which process is shown?diffusionrepirationrecombinationtranslation - 4. Multiple ChoiceWhen an extra base is inserted into the DNA sequence of a gene, the protein doesn't work. Which explains why?the base increases rate of translationthe base causes DNA to be transcribed in opposite directionthe inserted base causes the codons in the sequence to be incorrect for the desired proteinthe base signals enzymes to translate DNA rather than RNA
