In RNA synthesis a piece of RNA is used as a template for a synthesis of the new TNA strand.
False
Because a bacterial chromosome is circular it would not have an ARS.
False
The Binding site of DNA polymerae is called a Promoter.
False

True
Prokaryotic cells can perform mitosis but never meiosis.
False
DNA replication is the first step in both mitosis and meiosis.
False
A tumor can be traced back to one initial cell called a founder cell.
True
Gametes contain a haploid number of chromosomes
True
Inactivation of apoptosis is associated with cancer production.
True
An animal somatic cell would be a diploid cell.
True
The inability to control mitosis is associated with cancer developments.
True
Cells that divide stop the cell cycle at G2
False
Cyclins are proteins whose concentrations vary with the phases of the cell cycle
True
Osteoporosis is associated with accelerated apoptosis
True
According to the cell theory a virus is the only living thing without a plasma membrane.
False
A cation is an atom that has lost one or more electrons.
True
In biological bonds atoms intereact based on their electron configurations.
True
A hydrogen bond forms when a hydrogen atom is covalently attached to two seperate electronegative atoms at the same time.
False
A hexose sugar and a pentose sugar would both be examples of monosacharides.
True
The nucleotide ATP is used to make both DNA and RNA.
False
A buffer is used to make a solution more acidic.
False
The eukaryotic cell is larger than the prokaryotic cell
True
Where ever a ribosome is found protein synthesis will occur.
True
The functional site of a nucleic acid is always is always the same as its site of synthesis.
False
Sucrose is the sugar that is transported throughout a plant.
True
A fat is a tigyceride that is a solid at room temperature.
True
A cell with its cell membrane removed is called a protoplast.
False
Since they do not have a nucleus prokaryotic cells also do not have any DNA.
False
Microtubules and microfilaments help determine the shape of a cell.
True
A nucleus and a plasma membrane are structures common to all cells.
False
All movement processes that require a protien also require input of cellular energy(not the energy from the concentration gradient of the molecule being moved.)
False
Steroid receptors are examples of intinsic membrane proteins.
False
A biological process would have a negative Gibb's Free Energy.
True
A nuclear pore would be an example of a gated channel.
False
G-proteins are called G because they are associated with guanine nucleotides.
True
Excluding the mitochondria all protein synthesis in an animal cell starts and ends in the cytoplasm.
True
An SRP would be an intinsic membrane protein.
False
Exocytotic Vesicles originate from the ER.
True
A Hormone could be an example of a ligand.
True
A kinase is an enzyme that adds phosphate groupts to other enzymes
True
One Way to regulate enzyme activity is by adding a phosphate to the enzyme.
True
NADH and Mg2+ are two examples of enzyme co-factors.
False
ATP is commonly used to overcome the activation energy in biological reaction.
False
A ribozyme is a protein that catalyzes a change in RNA
Fale
Photosynthesis is a carbon reduction pathway.
True
Without oxygen photosynthesis would come to a halt.
False
All the intermediates in glycolysis are phosphorylated.
True
The study of enzymes is called thermodynamics

Most of the energy liberated during aerobic respiration is lost as heat.
True
The sun provides the electrons that are needed for photosynthesis.
False
