What comes to you mind when you hear or see the word genetics?

Open Ended

What do you think DNA is?

Open Ended

Do only living things have DNA?

Open Ended

Do only living things have DNA?

Open Ended

Viruses have DNA and RNA. Are viruses considered to be living?

Open Ended

Viruses are nonlivng since they cannot self replicate. They cannot make copies of themselves. Why would viruses need DNA?

Multiple Choice

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

DNA is called the blueprint of life, but there are nonliving things like viruses that have DNA. Why do you think DNA is still called the blue print of life?

DNA is a blueprint for proteins

• DNA is called the blueprint of life because it contains the instructions needed to make proteins.

• DNA does this by controlling protein synthesis (How proteins are made). Proteins do most of the work in cells, and are the basic unit of structure and function in the cells of organisms

Multiple Choice

DNA is called the blueprint for life. This is because DNA is the blueprint to make

• proteins

• cell pieces

• RNA

• Polymerase

DNA Structure Review

• DNA consists of two molecules that are arranged into a ladder-like structure called a Double Helix.

• DNA is a molecule classified as a Nucleic acid. It is made up of millions of tiny subunits called Nucleotides. 

• Each nucleotide consists of: Phosphate group Pentose sugar Nitrogenous base

Multiple Choice

What does DNA stand for?

• Deoxyribonucleic acid

• Denitrogenous acid

• Deribonucleic acid

• Diribonucleic acid

Multiple Choice

DNA and RNA both belong to which group of macromolecules?

• Proteins

• Lipids

• Nucleic Acids

• Carbohydrates

Multiple Choice

In eukaryotes, which organelle is DNA usually found in?

• cell membrane

• vacuole

• chloroplast

• nucleus

Multiple Choice

The information in DNA is written according to the genetic code and carried by the -

• sequence or arrangement of nucleotides

• direction of the phosphate groups
