Term
What would you use to reduce the size of the DNA pieces?
Definition
Restriction enzymes.
Term
Restriction enzymes functions
Definition
Make the DNA pieces easy to manage, DNA fingerprinting and splicing.
Term
Restriction endonucleases
Definition
Restriction enzymes, cuts DNA sequences by recognizing a certain pattern of nucleotides.
Term
Restriction enzymes recognize a ____ sequence of ____ nucleotides in length. These were orginially isolated in _______ although many of the newest enzymes have been created by ______ in the lab.
Definition
palindromic, 4-6, bacteria, mutagenesis
Term
The patterns of each enzyme are different, the type of cut is also important, because...
Definition
it helps determin the suitability of the DNA pieces for any subsequent procedures. By matching the enzymes produced pieces, the fragments can be inserted into similar vectors.
Term
There are two types of restriction enzymes ones that make a ____ cut, and one that produces "_____ " Which one makes it difficult to re-anneal like pieces.
Definition
Blunt, jagged.
Blunt.
Term
The jagged type creates two overhanging fragments called _____ ___ Any sequence with these van be joined together using a ______
Definition
Sticky ends. DNA ligase.
Term
What can Restriction Maps be used for?
Definition
to identify differences between DNA pieces. This can help distinguish the differences between DNA pieces which helps with diagnosing genetic disorders, evolutionary relationships, and forensics.
Term
A mutation...
Definition
alters the restriction map of a gene.
Term
Two enzymes used in lab
Definition
EcoR1 and Bam H1
