Q.1
Which best describes stem cells?
stem cells can only come from embryos
stem cells can only come from adult bone marrow
stem cells do not ever change
stem cells can develop into different specialized cells
Q.2
What is the primary purpose of using restriction enzymes in gel electrophoresis?
It restricts the number of base pairs that can be tested in a sample.
It makes the testing simpler by moving the strands into the gel faster.
It allows the DNA strands to be charged so the electrical current can send the strands into the gel.
It allows the strands of DNA to be cut into various lengths for testing.
Q.3
Which are most closely related to biotechnology?
medicine and agriculture
construction and engineering
water treatment and electricity generation
communication and information technology

Q.8
Which best describes recombinant DNA?
DNA that has been deactivated by enzymes
DNA found in organelles other than the nucleus
inserted genes from one organism into another to direct it to produce a protein
