What are nitrogenous bases?
200
This is the first step in DNA replication.
What is unwinding of the helix?
200
This type of RNA is created by copying a specific gene from the template DNA, which will tell which protein to make.

The following scenario describes which theory: The gene for blond hair and blue eyes is often inherited together.
What is gene-chromosome theory?
300
These three molecules make up a nucleotide.
What is the nitrogenous base, deoxyribose (sugar) and a phosphate?
300
This is the second step of the DNA replication process.
What is the helix unzips the weak hydrogen bonds?
300
This type of RNA brings amino acids from the cytoplasm to the ribosome for polypeptide construction.
What is tRNA or transfer RNA?
300
Translation occurs here in the cell.
What is the ribosome?
400
This law of genetics states that when organisms pure (homozygous) for contrasting traits are crossed, all of their offspring will show the dominant phenotype.
What is the law of dominance?
400
Watson and Crick first discovered the DNA molecule and described its shape as this.
What is as a double helix?
400
This polymerase binds the new nitrogenous bases to the parent DNA, which is the last step of DNA replication.
What is DNA polymerase?

This RNA makes up part of the ribosome.
What is rRNA, or ribosomal RNA?
500
This is the process that connects the amino acids together in a polypeptide chain.
