Hi! :)
Based on information given out by the National Health Service, if a person is choking but is still actively able to speak and breath you should have them try and cough to get out anything that is stuck in the esophagus. Knowing this, your answer should be A.
Hope this helps!
Some rules are:
-A team must have 9 players to start,
-Bats must be official softball bats(no metal screws or screw-in cleats are allowed)
Answer:
The student forgot to add reverse transcriptase
Explanation:
Reverse transcriptase is an enzyme, also called DNA polymerase or RNA-dependent, responsible for carrying out the transcription process, which corresponds to an “inverted copy”, as opposed to the cellular pattern. In other words, this enzyme polymerizes DNA molecules from RNA molecules, the opposite of what commonly occurs in cells.
The student, exposed in the question, wanted to create cDNA through an isolated and amplified mRNA sample, but this student did not use reverse transcriptase, so it would be impossible for his experiment to have good results.
