Universal Genetic Code
Which types of organisms use Nucleic acids for their genetic code?
All organisms
What biotechnology tool is responsible for cutting DNA at certain sequences?
Restriction Enzymes
Enzymes are made of this macromolecule.
Proteins/Amino Acids
What are the 5 possible nucleotides used by organisms? (letters are fine)
T, A, G, C, U
What biotechnology process makes millions of copies of DNA?
PCR
Enzymes do this to the speed of a reaction.
Increase
What are the parts of a nucleotide?
Phosphate, Sugar, Base
A researcher wants to make a transgenic organism, but uses different Restriction Enzymes on each organism's DNA. What will happen?
Different base-pairs would be cut -
They wouldn't match up -
They would be incompatible.
Which one of the following is NOT part of the definition of a gene?
A. A physical unit of heredity
B. Encodes a protein
C. Segment of a chromosome
D. Responsible for an inherited characteristic
E. Only contains A and T.
E
Can a transgenic organism or a genetically modified organism pass their traits on to their offspring?
Yes!
It won't work as well.
Why is it possible to splice a jellyfish gene into pig DNA?
The genetic code is universal
All organisms have DNA
Tomatoes are healthy, but require a lot of water to grow. Scientists can splice in genes to the tomato DNA to reduce the water needed to grow them. What would the tomatoes be called after this process?
Genetically modified organisms (GMO)
or
Transgenic Plants
What enzyme would break down the sugar lactose?
Lactase
