DNA and Beyond
Surpriseeeeee!
100
This is the growing and working phase of the cell cycle
What is interphase
100
These are changes in the DNA, or genetic code of a cell
What are mutations
100
These are the four stages of mitosis
What are prophase, metaphase, anaphase, and telophase
100
DNA has a double helix (twisted ladder) structure. What are the 4 nitrogenous bases that make up DNA?
What are adenine, cytosine, guanine, and thymine
100
This is the name of the first mammal to be successfully cloned
Who is Dolly
200
This is the percentage of time spent in interphase
What is 90%
200
This word refers to any substance that can cause cancer
What is a carcinogen
200
In this phase of mitosis, the sister chromatids are pulled apart and move toward the opposite poles of the cell
What is anaphase
200
This is a short section of DNA that contains the instructions to make a specific protein
What is a gene
200
This process divides the cytoplasm into two daughter cells
What is cytokinesis
300
The cell cycle ends when _________________
What is the cell dies
300
These types of tumours are masses of cells that grow but stay in one place and usually do not interfere with normal functioning
What are benign tumours
300
Some simple plants and animals can use mitosis to do reproduce, which is called
What is asexual reproduction
300
DNA has a special ability to do this during interphase
What is copy itself (replicate)
300
This type of asexual reproduction is when the offspring begins as a small growth on the parent and eventually breaks off.
What is budding
400
A normal human body cell has 46 chromosomes. After mitosis, how many chromosomes should be in each daughter cell?
What is 46 chromosomes
400
According to recent statistics, what percentage of Canadians will develop cancer at some point in their lives?
What is 40-45%
400
This is made of microtubule fibres and moves the chromatids during cell division
What is the spindle
400
In the DNA model lab we did, what did the licorice represent?
What is the sugar/phosphate backbone
400
The sea star uses this form of asexual reproduction to reproduce
What is fragmentation
500
This is what each chromosome and its copy are known as
What are sister chromatids
500
This word means the spread of cancer cells away from their original location
What is metastasis
500
This stage of the cell cycle is often thought of as "reverse prophase"
What is telophase (events happen in reverse - chromosomes reach poles, spindle disappears, chromosomes get thinner)
500
Each 3 letter word of DNA codes for the production of one of these
What is an amino acid
500
All of an organism's DNA is called this
What is the genome
