Total questions: 11
Worksheet time: 11mins
Which of the following technologies determines the expression of a gene?
Genetic Association Study
FISH
PCR
Electroporation
Which of the following is not a medical application of gene cloning?
Production of hormones for treating conditions like diabetes and dwarfism
Production of viral subunits for some vaccines
Genetic testing for carriers of harmful alleles
These are all medical applications of gene cloning
Multigene families are:
Identical or similar genes that have evolved by gene duplication.
Usually clustered at the telomeres
Equivalent to the operons of prokaryotes
Groups of enhancers that control transcription
What is the function of restriction endonucleases in biotechnology?
Cuts DNA strands at specific points to expose sticky ends
Restricts the expression of DNA
Relieves tension in the DNA strand
Allows conversion of RNA to DNA by viruses
Which of these are not an example of Cloning Vector for transfer of DNA? (may be more than one)
Plasmid
Needle
Bacteriophage
Norovirus
Which of these is not a step of a polymerase chain reaction (PCR) cycle to amplify DNA
Annealing Step
Initiation Step
Denaturation Step
Extention Step
What is a 'Transposon' an example of?
Satellite DNA
A Short Tandem Repeat
A Transposable Element
A Pseudogene
Why are short tandem repeats useful for forensics?
The locus of short tandem repeats differs from person to person
Number of short tandem repeats varies significantly from person to person
Only identical twins vary in the number of short tandem repeats
The number of short tandem repeats is difficult to identify by genetic research
Which of the following is not a method to insert foreign ‘DNA’ into a nucleus?
Make cells competent by treating with compound that alters membrane permeability
Electroporation
Microinjection into nucleus
Radiative Transplantation
Which of the following is not required in reproductive cloning? (Dolly)
Pre-fertilized Egg
Mammary Cell Donor
Surrogate mother
Egg Cell Donor
Approximately what percentage of the genome is non-coding DNA?
5%
10%
15%
20%
