Clone Identification and Expression

1

A radioactive probe can take what forms?

1

Probes can be

1

Name the two ways probes can be designed

1

What is codon bias?

1

80% of Phe codons are TTC, 20% are TTT

1

If the protein is an enzyme it can be found by adding the substrate

1

State the possible forms of Ig's for protein separation?

1

Probes needn't be 100% accurate to work

1

For a Western Blot, how is the DNA stuck to the membrane?

1

Once the DNA has been bound, what happens next?

1

In an expression vector, where is the new gene added?

1

Name the parts on the vector

1

More compliated vectors have proteins tagged for purification

1

What is involved in His Chain Purification?

1

His Purification uses Histadine's affinity for what metal?

1

His-tagged proteins will bind to Nickel in a column. Others that don't bind will be washed off.

1

The PET system involves using a promoter for the protein that you can control the expression of

1

What promoter is used in the PET system to control protein expression?

1

In the PET system, what promoter is used to control the T_ expression?

1

What is required for a good shuttle vector?

1

Shuttle vectors are usually plasmids with additional sequences

1

Shuttle vectors for yeast/fungi need

1

A baclovirus would be used as a vector into what?

1

Secretion of certain proteins can be caused by what?

1

Why are there two origins in the Yeast shuttle vector?

1

What is the method of selection in yeast?

1

Like bacteria, yeast cannot take up linear DNA

1

What does a YAC contain that a plasmid does not?

1

Yeast can allow DNA to be directly inserted into its genome

1

How can yeast accept DNA into its genome?

1

In order to directly insert a gene, you must flank the gene with identical stretches of the part of the genome you want to insert it in

1

Plants would use an aglobacterium T1 plasmid

1

How do you replicate transformed plant cells?

1

Mammal shuttle vectors are the same as yeast vectors, but the yeast origin is replaced with what?

1

Retroviruses can also be used to insert transgenes into mammilian genomes by packing the transgene in a retroviral capsule
