DNA & Chromosomes
The complete set of genetic material in an organism.
What is a genome?
A change in DNA sequence.
What is a mutation?
A disorder caused by a mutation in a single gene.
What is a genetic disorder?
A process that examines DNA for inherited conditions.
What is genetic testing?
Mutations can sometimes improve survival in an environment.
What are beneficial mutations?
Humans have 46 of these, arranged in 23 pairs.
What are chromosomes?
Mutations can occur due to mistakes during this process.
What is DNA replication?
A disorder caused by missing or extra chromosomes.
What is a chromosomal disorder?
One benefit of genetic testing is early detection of this.
What are diseases or disorders?
Harmful mutations may reduce this biological advantage.
What is survival or fitness?
These structures are made of DNA and contain genes.
What are chromosomes?
This type of mutation affects only one base in DNA.
What is a point mutation?
This condition is caused by an extra chromosome 21.
What is Down syndrome?
One risk of genetic testing is loss of this personal information.
What is privacy?
Genome research could help future generations by preventing this.
What are inherited diseases?
A segment of DNA that codes for a trait.
What is a gene?
Mutations can change this molecule’s shape and function.
What is a protein?
Nondisjunction most often occurs during this type of cell division.
What is meiosis?
This project mapped all human genes.
What is the Human Genome Project?
Studying genes helps scientists understand how traits are this from parents to offspring.
What is inherited?
The way human chromosomes are organized into pairs by size.
What is a karyotype?
When chromosomes fail to separate during meiosis.
What is nondisjunction?
Genetic disorders affect individuals by changing this cellular product.
What are proteins?
Genome research allows doctors to create treatments based on a person’s DNA.
What is personalized medicine?
This scientific advancement has transformed medicine by helping scientists understand human DNA and disease at the molecular level.
