DNA structure, replication and mitosis

Match the following nucleotide bases the way they form base pairs:

• Guanine

• Guanine

• Thymine

• Cytosine

• Cytosine

• Thymine

• Adenine

• Adenine

Where in a eukaryotic cell is the DNA located?

• nucleus

• ribosomes

• golgi apparatus

• lysosome

Answer explanation

Eukaryotes keep their DNA in the nucleus.

In Prokaryotes, the DNA just floats in the cytoplasm.

Match the following enzymes to their roles in DNA replication:

• Primase

• Adds nucleotides to form the new strand of DNA

• Ligase

• Fills in the gaps to complete the finished DNA strands

• Helicase

• Starts the DNA replication process by adding a small piece of RNA

• DNA polymerase

• Unwinds and seperates the parent DNA strands

Amino acids are the monomer for which macromolecule?

• proteins

• nucleic acids

• carbohydrates

• lipids

What do we call a nucleic acid that contains the sugar deoxyribose?

• RNA

• Ribonucleic Acid

• DNA

• Amino Acid

What do we call the threadlike structures within the nucleus containing the genetic information that is passed from one generation to the next?

• DNA

• Protein

• Amino Acid

• Chromosomes

What do we call Watson and Crick's model of DNA that has two strands wound around one another?

• Twisted

• Double Helix

• Ladder

• RNA
