What are the 2 types of strains during DNA?
Smooth strain and
rough Strain
During transcription, what molecule matches up with one strand of the unzipped DNA?
mRNA
What can mutations be increased by?
radiation & chemicals
How do specific restriction enzymes work?
They cut DNA at specific sequences of nucleotides
What are the correct base pairing rules for DNA?
Adenine with Thymine; Guanine with Cytosine
Why is crossing over so important during meiosis?
It increases genetic diversity
What is DNA separated by
gel electrophoresis
Because mutations cannot be totally controlled, creating useful bacterial strains through mutation requires
Lots of trial and error
What are the building Blocks of a DNA molecule?
Nucleotides
Which process includes light-independent reactions?
