What is a codon?

• It is a three letter section of bases that are read by ribosomes to stamp amino acids into a protein
• They are the codes on the DNA (hence "code-on"
• It is a type of mutation that occurs when there has been a substitution, deletion or insertion.
• It is a made up word for this quiz. Nice try, Wampler.

What are the building blocks of proteins called?

• DNA
• RNA
• Ribosomes
• Amino Acids

In DNA, Adenine bonds with ______________.

• Guanine
• Thymine
• Cytosine
• Adenine

What is the central dogma of biology?

• Proteins are made from RNA that assembles amino acids through DNA ribosomes.
• RNA copies all information for an organism onto DNA which assembles ribosomes, and creates amino acids from proteins
• DNA is the blueprint for an organism. RNA copies specific sections that need to be built and transfers that information to a ribosome which assembles proteins out of amino acids.
• RNA is the blueprint for an organism. It copies its information onto DNA, which takes amino acids (like lego building blocks) and assembles those acids into proteins.

Genes for medically important proteins can be cloned and inserted into bacteria, as shown in the diagram above.

Why can bacteria recognize a human gene and then produce a human protein?

• DNA replication in bacteria and humans is the same.

• Bacterial cells contain the same organelles as human cells

• The basic components of DNA are the same in humans and bacteria.

• Bacterial cells and human cells contain the same kind of chromosomes.
