I need the dropdown menu to answer this question
Answer:
PCR=Polymerase chain reaction
Explanation:
Step one you should have a clean slide and coverslip, step two is you place ONE drop of water in the middle of the slide, step three place the edge of a cover slip on one side of the water drop, step four cover the slip on top of the drop at a fourty five degree angle, step five place the slide on the stage and view it at first with the red banded objective, you can rotate the nosepiece to view the slide with different objectives.
Answer:
introduces a premature stop codon into the mRNA
Explanation:
A nonsense mutation is a mutation in which an amino acid–specifying codon is changed into a termination codon or stop codon. A stop codon is a codon that does not code for any amino acid and serves to terminate the process of protein synthesis as ribosomes encounter it on the mRNA.
There are three stop codons: UAA, UAG, UGA. A nonsense mutation introduces a stop codon in place of an amino acid encoding codon. It results in the formation of truncated protein which is shorter than the normal protein. Truncated proteins are mostly nonfunctional.
