Nucleic Acids
This enzyme adds new nucleotides to a DNA strand during DNA replication.
What is DNA polymerase?
This term describes any agent, such as asbestos, that causes cancer.
What is a carcinogen?
This type of membrane consists of two layers of phospholipid molecules.
What is a phospholipid bilayer?
These three common hexose sugars have six carbon atoms per molecule.
What are glucose, fructose and galactose?
What is the only food that supposedly never spoils?
What is honey?
This process describes how DNA is used to produce mRNA.
What is transcription?
These are the four main stages of mitosis.
What are prophase, metaphase, anaphase and telophase?
These membrane proteins provide hydrophilic passageways for ions and polar molecules to cross the membrane.
What are transport proteins?
This reaction joins two monosaccharides together by removing a molecule of water.
What is a condensation reaction?
Which animal can survive for days without its head, provided its body remains alive?
What is a cockroach?
These two nitrogenous bases form three hydrogen bonds when paired together in DNA.
What are guanine and cytosine?
This protein structure is found at the centromere and provides an attachment site for spindle microtubules.
What is a kinetochore?
This network of protein filaments helps maintain cell shape and can be involved in changes in cell shape during movement.
What is the cytoskeleton?
This polysaccharide consists of β-glucose monomers and provides mechanical strength to plant cell walls.
What is cellulose?

What is a unicorn? 🦄
This enzyme is responsible for synthesising mRNA during transcription.
What is RNA polymerase?
During this phase of interphase, the cell checks newly replicated DNA for errors and prepares for division.
What is the G₂ phase?
This term describes the increase in the number of second messenger molecules produced in response to the stimulation of a single receptor molecule.
What is signal amplification?
This starch component consists of thousands of α-glucose molecules joined by 1,4 glycosidic bonds, forming an unbranched chain that coils into a helix.
What is amylose?
Which animal has fingerprints so similar to humans’ that they can sometimes be confused?
What is a koala?
This process decodes the genetic information carried by mRNA to produce a polypeptide.
What is translation?
These cells can divide repeatedly and produce daughter cells that either remain stem cells or differentiate into specialized cells.
What are stem cells?
Phospholipid molecules can move within the membrane without leaving their layer. What type of movement allows this to happen?
What is diffusion?
A triglyceride molecule contains three of these bonds, formed when fatty acids combine with glycerol.
What are ester bonds?
What is the only mammal capable of true, sustained flight?
What is a bat?
