100

A type of molecule that genes and chromosomes are made of.

What is DNA?

100

An instruction for making a protein molecule.

What is a gene?

100

The term for receiving genes from a parent.

What is inherit?

100

This term refers to how something works.

What is function?

100

Having gene versions that are exactly the same.

What is homozygous?

200

The specific part of a cell where genes are located.

What is the nucleus?

200

A specific form of a gene that provides instructions for a particular protein.

What is an allele (or gene version)?

200

An organism produced as the result of reproduction.

What is an offspring?

200

This term refers to the way something is shaped or constructed.

What is structure?

200

Having gene versions that are different.

What is heterozygous?

300

These cell parts build protein molecules by following instructions from genes.

What are ribosomes?

300

A characteristic that all members of a species possess.

What is a feature?

300

The process where two parents pass on genes to create an offspring.

What is sexual reproduction?

300

A protein molecule's function depends on its structure and how it does this with other molecules.

What is interact (or connect)?

300

For every feature, an organism has this many total copies of a gene.

What is two?

400

A long piece of DNA that contains many individual genes.

What is a chromosome?

400

A specific characteristic of an individual organism.

What is a trait?

400

The process where one organism duplicates its genes to create a genetically identical offspring.

What is asexual reproduction?

400

A protein that cannot perform its function, often because it fails to connect to other molecules.

What is a nonfunctional protein?

400

Any difference in traits between individual organisms.

What is variation?

500

A large molecule that performs essential functions inside an organism.

What is a protein molecule?

500

A random change to a gene that can sometimes lead to a brand-new trait.

What is a mutation?

500

Each parent passes on exactly this many of its two gene copies to its offspring.

What is one?

500

Structure determines function at this scale, which then determines the properties of the object.

What is the molecular scale?

500

Because of different gene combinations, these individuals can have different traits from each other and their parents.

What are siblings?
