Biology Review EOC 6H

Which of the following genetic disorders best describes the karyotype in the graphic above?

• inversion, chromosome 18

• trisomy, chromosome 21

• translocation, chromosome

• deletion, chromosome 5

In 1973, Stanley Cohen and Herbert Boyer inserted a gene from an African clawed frog into a bacterium. The bacterium then began producing a protein directed by the code found on the inserted frog gene. This same technology is used today to produce pure human insulin.

The newly synthesized genetic material in the bacterium is known as –

• recombinant DNA

• messenger RNA

• a multiple allele

• a gene mutation.

Scientists found members of a plant species they did not recognize. They wanted to determine if the unknown species was related to one or more of four known species – A, B, C, D. The relationship between species can be determined by comparing the results of gel electrophoresis of the DNA from different species. The chart below represents the results of gel electrophoresis of the DNA from the unknown plant species and the four known species.

Which two known plant species is the unknown plant species most closely related to?

• Species A & D

• Species C & D

• Species A & C

• Species B & D
