genetic mutation

What is the central dogma of molecular biology?

• The process of gene expression

• The process of DNA replication

• The process of cell division

• The process of protein synthesis

Which type of mutation occurs when one DNA base is replaced with another?

• Frame-shift mutation

• Missense mutation

• Point mutation

• Non-sense mutation

What is the result of a frame-shift mutation?

• Change in the reading frame of RNA

• Change in one amino acid

• Change in the DNA structure

• Change in multiple amino acids

Which type of mutation changes an amino acid from one to another?

• Frame-shift mutation

• Non-sense mutation

• Point mutation

• Missense mutation

What is the effect of a non-sense mutation?

• Formation of a stop codon

• Change in multiple amino acids

• Change in one amino acid

• No effect on the protein

Which type of mutation has a new amino acid of the same type as the original?

• Silent mutation

• Conservative mutation

• Missense mutation

• Nonconservative mutation

Which type of mutation has a new amino acid of a different type from the original?

• Silent mutation

• Conservative mutation

• Missense mutation

• Nonconservative mutation
