Cells & Proteins
What do rod cells do?
Rod cells identify black and white but not color.
What is a stimulus?
A detectable change in the enviroment.
True or false
Are genes and alleles related?
True
How do proteins affect traits?
What is a signal?
A chemical reactions within a human cell that travels along a nerve cell to the brain.
What do cone cells do?
Cone cells identify color.
What term is this?
A set of instructions that describe what amino acids to string together in a special order to make a given protein.
Genetic code
Can we pick what genes we get?
True or false
Are traits passed down?
True
What is a nucleus?
Organelle in cells that contains genes.
What do protein receptors do?
Protein receptors send signals when the corresponding molecule locks in with it.
What are proteins?
A special type of molecule in our bodies that can do things in our cells. A molecule made up of a chain of amino acids that performs tasks like sensing stimuli, signaling cells, chemical reactions and coursing throughout our bodies.
What are genes?
Chemical codes that contain instructions to make proteins.
True or False
No traits are visible
False, traits can be visible and invisible.
What is an allele?
Different versions of the same gene.
What happens when a molecule is the wrong one or doesn't lock in with the protein receptor?
The protein receptor will not function properly, therefore no signal is sent.
What is an inhereted trait?
A physical trait characteristic of a person that can be passed down from a parent to child.
Where are genes found?
Genes are found in the nucleus of a cell.
How do alleles affect traits?
Alleles are different versions of a gene that can affect traits.
What is an offspring?
A product of reproduction, a new organism produced by one or more parents.
What do reproductive cells do?
They combine to make an offspring.
The 20 different building blocks that make up all proteins in our bodies.
Amino acids
How are genes passed down?
Chromosone pairs split from each parent to make reproductive cells that contain genes and alleles.
Why do some people have different genes from their family?
Genes are chosen at random.
What are chromosones?
Thread-like structures made of DNA molecules that contain the genes and are found in the nucleus.
