The structure of DNA looks like this
What is a twisted ladder
100
The twisted ladder structure of DNA is also known as this
What is a double helix
100
This is what DNA replication is
What is a process in which an identical copy of DNA strand is formed for a new cell
100
What a mutation is
What is any change in the DNA of a gene or chromosome
100
What cancer is
What is a disease when cells grow uncontrollably, and damages the body
200
It took this many years for scientists to figure out that DNA looks like a twisted ladder
What is 100 years
200
The sides of the double helix are made up of these two substances
What are deoxyribose and phosphate molecules
200
How replication occurs
What is DNA unwinds and unzips and pairs with nitrogen bases in the nucleous
200
What a mutation causes
What is causes cells to produce an incorrect protein during protein synthesis
200
Some people are more likely to develop certain cancers because of this
What is inherited traits
300
DNA contains this for cells to make proteins
What is genetic information
300
These are the four kinds of nitrogen bases for DNA
What are adenine, thymine, guanine, and cytosine
300
Why replication is important
What is daughter cells need a complete set of DNA to survive
300
How mutations affect an organism
What is the organism's trait is different from what it would normally be
300
Three treatments that people with cancer undergo
What is surgery, radiation, and drugs
400
In 1951 this English scientist discovered DNA
Who is Rosalind Franklin
400
Ina genetic code, these codes for one amino acid
What is a group of three DNA bases
400
The pattern by which nitrogen bases always pair
What is Adenine-Thymine and Guanine-Cytosine
400
The two occurrences of mutations
What is 1. small change in DNA 2. chromosomes separate incorrectly during meiosis
400
What chemotherapy is
What is a treatment involving the use of drugs
500
In 1953 these two scientists published the structure of DNA
Who are James Watson and Francis Crick
500
The order of largest to smallest (nitrogen bases)
What is 1.organism 2. cell 3. chromosome 4. DNA 5.nitrogen bases
500
How DNA copies itself
What is the way nitrogen bases pair up= the new DNA strand exactly matches the order of original DNA
500
What mutations can be
What is harmful or helpful
500
More than this number are the amount of existing cancers to date
What is more than 100
