Which organelle is DNA usually found in?

• cell membrane
• vacuole
• chloroplast
• nucleus

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.

• RNA
• Ribosomes
• Amino Acids

NGSS.HS-LS1-6

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.

Which choice describes DNA after replication has taken place?

• one molecule with two original strands and one molecule with two new strands

• two molecules, each with one original and one new strand

• two molecules, each with two new strands

• two molecules, each with two old strands

At what point in the cell cycle does DNA replication occur and why?

• before a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions

• before a cell divides, to ensure that the DNA will fit into the resulting cells

• during cell division, to ensure that the DNA will fit into the resulting cells

• after a cell divides, to provide each of the two resulting cells with a complete set of DNA instructions
