DNA science quiz

Cell Differentiation

The process where cells(like stem cells) become specific cell types with unique functions

Ribosomes function

Help make proteins

Mitochondria function

Generate energy (ATP) in cells

Cell wall function

Rigid layer of protection for plants

Nucleus function

largest organelle in cells which store genetic information

Chlorplast function

convert light into glucose

cell membrane function

to regulate the movement of substances in and out of the cell.

Cells in cheeck

irregular shape allow for flexibility in mouth

cells in onion

compact and blocky protect and keep structure

4 types of tissue cells

Epithelial, Connective, Muscle, and Nervous tissue

Epithelial

protective lining for movement

Connective

supports and binds together tissues and organs

Muscle

allows for movement and heat production

Nervous

processes information

Phosphate group

circle part of nucleotide

Nitrogen base

Big hexagon/square part of nucleotide

5 Carbon Sugar

Hexagon part of nucleotide

Nucleotide

Building block of DNA(monomer)

Adenine goes with

Thymine

Cytocine goes with

Guanine

Hydrogen bonds

Weak strands holding bases together

Covalent bonds

strong bonds holding nucleotides together

Helicase

Enzyme that unzips DNA into two strands

DNA polymerase

enzyme that connects DNA strands and ensures complementary base pairing takes place

DNA replication

1. Helicase unzips DNA

2. DNA separated and new free floating nucleotides added

3. DNA polymerase ensures complementary base pairing takes place

Why is DNA replication important

Important to pass on genetic information

How does the structure of DNA allow for it to replicate?

Weak hydrogen bonds allow it to be separated
