1. FALSE: Translation takes place on ribosomes in the CYTOSOL, not the nucleus. mRNA exits the nucleus and enters the cytosol where it finds the nucleus.
2. FALSE: Three nucleotides code for ONE amino acid - the three-nucleotide "code" is referred to as a codon. Multiple codons can code for one amino acid; there are four different nucleotides (adenine, cytosine, guanine, uracil) that can be mixed in multiple combinations to code for twenty total amino acids.
3. TRUE.
4. TRUE.
5. TRUE.

Translation takes place on ribosomes in cytosol.Three nucleotides code for an amino acid.The third statement is true.Fourth and fifth are also true.first and second are false.point mutations are mutations in a single nucleotide.
