True
False
The point of genetic engineering is to transfer useful traits/characteristics such as:
pest resistance
disease resistance
drought tolerance
anti-bruising
All of the above
How has genetic engineering helped farming?
by developing better fertilizer for crops
by creating crops that resist some diseases
by producing soil that makes crops grow better
by producing faster ways to harvest crops
This laboratory procedure is known as
CLONING
gel electrophoresis
chromatography
use of a dichotomous key
In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
convert the DNA into gel
cut the DNA into fragments
change the color of the DNA
produce longer sections of DNA
A student performed a gel electrophoresis experiment. The results are represented in the diagram
below. Compared to the fragments at the top of the gel, the fragments at the lower end are
larger, and move slower
larger, and move faster
smaller, and move faster
smaller, and move slower
Which chemicals are used to cut DNA into fragments for a gel electrophoresis procedure?
enzymes
molecular bases
hormones
ATP molecules
This technique used to analyze DNA involves the
synthesis of new DNA strands from subunits
separation of DNA fragments based on size
production of genetically engineered DNA molecules
removal of defective genes from DNA
Once DNA has been extracted from the nucleus of a cell, it is exposed to ______ ______ that act like biochemical scissors to cut the DNA.
restriction enzymes
gel agarose
clotting factors
electric shock
