|
what is a gene?
|
'a protein recipe'
a small piece of DNA that contains the code for making a protein |
|
|
what are enzymes made of?
|
proteins
|
|
|
what role do proteins play in the cell?
|
proteins are important 'action' and structural molecules in the cell
eg: enzymes, channel proteins, structural proteins (cytoskeleton) |
|
|
where is DNA located in the cell?
|
nucleus
|
|
|
can DNA leave the nucleus?
|
no.
|
|
|
where are proteins made?
|
at the ribosomes
|
|
|
what is the 'central dogma' of the cell? this describes the information flow in the cell
|
DNA is transcribed to make mRNA.
mRNA leaves the nucleus and attaches to the ribosome. mRNA is translated to make a protein. protein does its job. |
|
|
what are the building blocks of protein?
|
amino acids
|
|
|
what are the four classes of organic molecules?
another way to ask is... what are the four key macromolecules in the cell? |
1. proteins
2. nucleic acids 3. polysaccharides 4. lipids |
|
|
what are the building blocks of each one of the macromolecules?
|
1. proteins -> amino acids
2. nucleic acids -> nucleotides 3. polysaccharides -> monosaccharides 4. lipids -> fatty acid, glycerol |
