Acquired vs Inherited
Acquired or Inherited?
Speaking Spanish
Inherited
A detectable change in the environment. For example, light, sounds, touch, chemicals, are what?
Stimulus
A molecule attached to our cells that can sense a stimulus and start a signal that can travel to the brain is called what?
A Receptor Protein
A chemical code that contains the instructions to build proteins is called what?
Genes
A molecule that stores instructions on how to make all the proteins our body needs is called what?
DNA
Acquired or Inherited?
Blue eyes
Inherited
What are the FOUR components of the TASTE sensing system?
flavor molecule
taste bud cell
facial nerve
brain
A special type of molecule in our bodies that performs tasks like sensing stimuli, signaling cells, causing chemical reactions, and regulating our bodies. A type of molecule that is built following the genetic code found in a gene.
Protein
The code of a gene determines the _________ of the protein.
Shape
We find DNA in what part of our cells?
The Nucleus
Acquired or Inherited?
Purple Hair
Acquired
A chemical reaction within a human cell that travels along a nerve cell to the brain is called a what?
Signal
Why do people sense things (ie taste) differently?
They have differently shaped receptor proteins (PTC receptor)
What do we call different versions of the same gene?
Alleles
What do we call the special wormlike structures of tightly wound DNA used to pass genes to new cells when cells divide?
Chromosomes
What is the definition of acquired trait?
skills we learn or physical changes that occur during our lifetime
Signals are transmitted to the brain through our what?
Nerves
Non-tasters cannot test PTC because why?
Their PTC receptor protein shapes do not interact with the PTC molecule.
Why do people have differently shaped proteins?
Because they have different alleles for that protein.
If we look at a karyotype, where is the gene for the greenish sensing opsin protein located?
The X chromosome (23rd)
What is the definition of inherited trait?
A physical characteristic of a person that can be passed down from generation to generation, like from a parent to a child
What is the final step of our sensing system?
The brain processes the signal
Tasters can test PTC because why?
Their PTC receptor protein shapes do interact and bind with the PTC molecule.
What protein did we discover is differently shaped for Joe and Becky, which causes their difference in vision?
The greenish sensing opsin protein
Segments of DNA with the code for making a specific protein is called what?
Genes
