What is not true about mutation according to Hugo de Vries theory?

Options:
A They are large and discontinuous changes
B Mutations are random and directionless
C They are heritable and establish new species
D A single step large mutation to produce a species can never occur

The correct answer is:
A single step large mutation to produce a species can never occur

Solution:
Hugo de Vries based on his work on evening primrose brought forth the idea of mutations - large difference arising suddenly in a population. He believed that it is a mutation that causes evolution and not the minor variations (heritable) that Darwin talked about. Mutations are random and directionless while Darwinian variations are small and directional. Hugo deVries believed saltation (single-step large mutation) caused the formation of species. Saltation is a single step large mutation.

What is not true for the genetic code?

Options:
A It is nearly universal
B It is degenerate
C It is unambiguous
D A codon in mRNA is read in a non-contiguous fashion
