---|---|---|---|---|
What is the cell membrane?
It controls what enters and exits the cell.
|
What is a pedigree chart?
This visual representation can be used to track inherited traits through several generations.
|
What is messenger RNA?
This molecule carries the genetic code from the DNA in the nucleus to the cytoplasm.
|
What is genetic engineering?
The process of altering a genome, whether it's a human or a viral genome.
|
What are enzymes?
These proteins catalyze chemical reactions in the cell and outside of the cell.
|
What are chloroplasts?
These organelles harness the sun's energy to produce food in autotrophs.
|
What is a karyotype?
This collection of chromosomes can be used to identify genetic problems.
|
What is DNA replication?
In both mitosis and meiosis, chromosomes must duplicate by this process.
|
What is gene cloning?
The production of many identical copies of the same gene.
|
What is an organ system?
It is composed of several organs working together for a common purpose.
|
What is the smooth endoplasmic reticulum?
This organelle produces lipids for use inside and outside the cell.
|
What is an inversion?
In this chromosomal mutation, a piece of a chromosome is turned 180 degrees and rejoined.
|
What is ribosomal RNA?
This complex molecule, made from a DNA template, forms the ribosomes.
|
What is gene therapy?
This process inserts genetic material into human cells to treat genetic disorders.
|
What is the Calvin Cycle?
In this process, carbon from CO2 is fixed to a molecule of RuBP and then through several enzymatic reactions, glucose is produced.
|
What are mitochondria?
These organelles break down glucose to provide cellular energy for metabolic processes.
|
What is a Barr body?
This highly condensed chromosome occurs in female mammals due to redundancy.
|
What is cancer?
This disorder can occur when cells multiply without internal controls to result in a large growth called a tumour.
|
What is the PCR? (Polymerase Chain Reaction)
This gene cloning process amplifies a specific DNA sequence, creating billions of copies in a few hours.
|
What is visible light?
This component of the electromagnetic spectrum ranges from 380 nm to 750 nanometres.
|
What is apoptosis?
This process occurs as cells reach their normal end of life.
|
What is non-disjunction?
In this abnormal process, spindle fibres pull a chromosome to the wrong side of a dividing cell.
|
What is protein synthesis?
This process involves amino acids being attached to each other to form a polypeptide on the ribosomes.
|
What is the fruit fly?
Dr. David Suzuki studied genetics using this insect for his research.
|
What is a sense of humour?
This quality in animals like humans can get them through difficult times with less stress. It also makes them laugh.
