A scientist might conduct research to get answers to a question and to make theories and studies.
Answer:
Aerophobia
Explanation:
A phobia is an irrational fear of something. It can persist even when we know that we will not be harmed.
Aerophobia is the fear of flying or being on a flight (aeroplanes, helicopters, etc.). Experiencing this fear will often result in extreme anxiety and discomfort. Some doctors prescribe anti-anxiety medication for people who have aerophobia and need to take a flight.
To prepare a primer using only one type of nucleotide for the formation of cDNA, the primer most likely to be successful would be oligo-dT primer.
A primer is a short stretch of nucleotides of either DNA or RNA that bind to the stretch of DNA and also help in its identification.
Oligo-dT primers contain a short stretch of deoxythymidines. It is the most preferred type of primer for synthesizing the cDNA using reverse transcriptase. They have very high specificity and also allows to study various gene pools all simultaneously. They are suitable for m-RNAs containing a poly-A tail in them.
