What is Sexual Reproduction?
A method of reproducing offspring.
What do you call DNA that is wrapped (Tightly for some reason, They're sensitive ya know!) into bundles that make it easier for the cell to move around?
Chromosomes.
(I tried to make a chromosome pun, But all the good ones were already paired up!)
(True or False)
Parents can control which chromosomes they pass onto their offspring.
False
How do people get their genes from their parents?
People get half of their genes from their mother and the other half of their genes from their father.
What is Offspring?
The product of reproduction, A new organism produced by one or more parents.
What is Heredity?
The passing of genetic information from parents to offspring.
Why do you think sexually reproducing organisms don't pass on all of their genes to their offspring?
The offspring would have way too many genes.
How long would one uncoiled DNA Molecule be?
(Hint: Its the size of a White Rhino!)
Up to 6 feet long.
How does a proteins structure affect its function?
A protein’s structure/shape determines how it will function in the body.
What is Genetic code?
A set of instructions to build Proteins.
What are Proteins?
A special type of molecule in our bodies that can do things in our cells, Causing a chemical reaction.
Where in the cell can we find the DNA?
(Better call Dora or Blues Clues!)
The Nucleus (Of the cell).
Why don't we have all the same alleles as our parents?
They cannot pass all of them because they can only pass on one from each pair, Plus they are random.
How a protein is functioning will determine the traits a person will have or express.
What are Amino acids?
The fundamental building blocks of proteins.
(Basically Protein Legos!)
What is a Dominant and Recessive gene?
Alleles that express themselves either when present in the Genotype or when two copies are present.
Why does the DNA in the Chromosomes need to uncoil?
So the code can be “read” and proteins can be made.
Do all species of plants and animals have 46 chromosomes? (Give an example)
No, Chickens have 78 and Strawberries have 14.
How does someones genes affect the structure of their proteins?
The structure of proteins is determined by the combination of genes (or alleles) someone receives from their parents. The genes give the instructions to build a specific shaped protein.
What is a Genotype?
An organism's genetic makeup, The specific set of genes they carry.
What is Homozygous?
Having two identical alleles for a particular gene.
What is a Karyotype?
A collage of photographs of real chromosomes.
What is the study of genes called?
(Hint: It kinda sounds like Economics!)
Genomics.
How is it possible that people can have traits that others in their family don't have?
People can have traits that others in their family do not have because its a random process that provides the offspring with half of its genes from the mother and the other half from the father. No two siblings will receive the exact same allele combination, except for identical twins.
What is a Phenotype?
The observable traits or characteristics of an organism, Influenced by its Genotype.
