3. Instructions: You will have up to 2 minutes to answer each question
If more time is required we will go back to that question after the quiz

Surface proteins/sugar tails act as cell _______________ markers.
Phospholipid bilayer, “glycoprotein” and transport proteins

8. Question #5 What do ribosomes make? _______________
This organelle sorts and packages proteins and gets them ready for transport. _____________
As the magnifying power of a microscope increases, the field of view ______________
Too small to see with naked eye

12. Genetics

13. DNA
DNA: (deoxyribonucleic acid) the material found in the cell nucleus that contains genetic information
DNA is inherited from your parents and it codes for characteristics such as hair colour, widow’s peak, eye colour, and ability to curl the tongue
DNA is typically found in a double-helix shape with a sugar-phosphate backbone and nitrogenous bases (adenine, thymine, guanine and cytosine).
Sugar + phosphate + one base = nucleotide

14.
Although all living things (i.e. bats, fungus, and whales) all have the same four nucleotides, each individual is unique because their sequence of nucleotides (genes) is different from all other individuals
Chromosomes: thread-like structures made mostly of DNA (there is some protein), found in the nucleus of a cell
Gene: segment of DNA that controls protein production
Genetic code: determines the production of specific proteins that combine to make an organism function
