DNA Structure
What are the subunits making up DNA
When does DNA Replication occur?
During S Phase of the cell cycle
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
This organelle is found only in eukaryotes and not prokaryotes. It contains genetic information.
The nucleus
What do we call the spheres of membranes that carry material throughout the cell?
Vesicles
What is the complementary DNA strand of CGTATG?
GCATAC
What is the first step in DNA replication?
DNA Helicase unwinds the DNA molecule
This organelle provides the cell with the ATP it needs to perform its functions and activities.
mitochondria
Bacteria are the only example of this cell type.
prokaryote
What makes the Rough ER rough?
ribosomes
Name the 3 parts of the nucleotide
What is Phosphate group, 5-carbon sugar, nitrogenous bases
This is the strand of DNA that is replicated continuously
leading strand
These organelle provides structural support to plant and bacteria cells.
cell wall
What is the Greek meaning for eukaryotic
true nucleus
Name any function of the golgi body
Modifies proteins & lipids made in the ER
Finishes carbohydrate synthesis
Packages and sends products to their final destination
What type of bonds join base pairs on DNA?
Hydrogen Bonds
The enzyme that replaces the RNA primers on the lagging strand?
DNA Polymerase 1
Their function is to follow DNA instructions to make proteins.
ribosomes
Difference between prokaryotic and eukaryotic ribosomes
Name an organelle NOT included in the end-membrane system
mitochondria, chloroplast
What parts of the nucleotide make up the backbone of the DNA structure?
sugar and phosphate
The direction DNA is synthesized in
5' --> 3'
list one statement of the cell theory... there are 3
1. All living things are made of cells.
2. Cells are the basic unit of life.
3. Cells only come from other cells.
Prokaryotes have three different shapes. What are they?
rod , spherical, and spiral shaped
Name any of the functions of the Smooth ER
Main function: lipid synthesis
Carbohydrate synthesis
