Explanation:
Translation is catalyzed by a large enzyme called a ribosome, which contains proteins and ribosomal RNA (rRNA). Translation also involves specific RNA molecules called transfer RNA (t-RNA) which can bind to three basepair codons on a messenger RNA (mRNA) and also carry the appropriate amino acid encoded by the codon.
Let's go through the choices!
A. They're unaffected by positive self-talk.
Let's pretend you are scared of thunder. If you tell yourself, "I will not let thunder scare me; it will not hurt me," you will be less scared! So, A is not the answer.
B. They're harmless, because they're imaginary.
If you are scared of something, it can damage your mental health, which is not harmless. So, B is not the answer.
C. They're a kind of negative self-talk.
Being afraid of something is usually due to an overexaggeration in your mind. So, C is a good answer.
D. They're a kind of positive reinforcement.
Being scared is not positive. So, D is not the answer.
The answer is C!
