2. Identify the point (substitution) mutation from the following DNA sequence:ATG CCA AAT
3. Despite the successful cloning of human embryos, much of this research has been halted due to:
4. Where does protein synthesis take place?
5. A set of steps where genes from one organism are placed into the DNA of an organism of a different species, with the goal of having that organism produce the trait of the other species
6. Reorder the steps of carrying out electrophoresis:1.Cut DNA sample with restriction enzymes and amplify them by PCR2.Place Agarose gel in the chamber facing well to negative electrode and add buffer solution3.Loading sample with a micropipette4.Covered the chamber and apply electrical current5. Remove the gel and stained to visualise the bands
