DNA Basics
Inside the nucleus of a cell is where you'll find this genetic material.
What is DNA
Students in a classroom have unique traits because they inherited different combinations of these from their parents.
What are traits?
This term describes the process by which genetic traits are passed down from parents to offspring, and it involves the combination of alleles from both parents.
What is inheritance?
A physical characteristic that helps an organism survive in its environment.
What is an adaptation?
This Austrian monk is famous for his experiments with pea plants that laid the foundation for modern genetics.
Who is Gregor Mendel?
In DNA, Adenine always pairs with this base.
What is Thymine?
When crossing parents with genotypes AA and aa, all offspring will have this genotype. (Tell me capital and lowercase)
What is Aa?
When both alleles are expressed equally in the offspring, such as in blood type AB, this type of inheritance occurs.
What is co-dominance?
The process where organisms with favorable traits are more likely to survive and reproduce.
What is natural selection?
When working with black (dominant B) and white (recessive b) fur in animals, there are this many possible genotype combinations.
What is three?
These four letters represent the bases that make up DNA: A, T, C, and G.
What are Adenine, Thymine, Cytosine, and Guanine?
The different forms of a gene are called this.
What are alleles?
When a flower with red petals (P1) and a flower with white petals (P2) produce offspring with pink petals (P1P2), this type of inheritance has occurred.
What is incomplete dominance?
Lions with larger jaws being more successful at hunting than those with smaller jaws is an example of this evolutionary process.
What is natural selection?
The DNA sequence ATCGGCTA would be transcribed into this RNA sequence.
Have a group member write it down
What is UAGCCGAU?
These white strings that appear when extracting DNA from an onion are actually unwound chromosomes, genetic information, and DNA itself.
What is DNA?
When crossing two heterozygous tall pea plants (Tt), the probability of getting a tall plant is this percentage.
What is 75%?
Carlos inherited T1 from his tall father and T2 from his short mother, resulting in average height; this demonstrates this type of inheritance.
Correct Response: What is incomplete dominance?
The gradual change in a species over time due to natural selection is called this.
What is evolution?
When a protein cannot fit through a certain space due to an incorrect shape, this genetic event has likely occurred.
What is a mutation?
This process creates an RNA copy of a gene that can be used to build proteins.
What is transcription?
The observable characteristics of an organism, such as eye color or height, are called this.
What is phenotype?
When one allele completely masks another, it's called this type of inheritance.
What is dominant inheritance?
What is regular/normal dominance
What scientist came up with the idea of natural selection?
Who is Charles Darwin
In a Punnett square showing a cross between two heterozygous parents (Bb × Bb), the probability of offspring having the recessive phenotype is this fraction.
What is 1/4 (or 25%)?
