|
protein |
consists of 1 or more polypeptides |
|
|
peptide bond |
amino acids of a polypeptide joined by this covalent bond |
|
|
N terminus |
beginning of polypeptide chain |
|
|
C terminus |
end of polypeptide chain |
|
|
amino acid |
consists of amino group, carboxyl group, alpha carbon, and R group |
|
|
aminoacyl, peptidyl, exit |
entrance, attachment, and exit point where tRNA binds during different stages of polypeptide synthesis |
|
|
housekeeping genes |
always transcribed/expressed genes. Needed to continually run the cell |
|
|
conditionally expressed genes |
can be shut off occasionally, transcribed and translated based on the needs of the cell |
|
|
interchromosomal domain |
space between chromosomes |
|
|
regulatory segments |
cis-acting sequence elements bounding trans-acting factors |
|
|
CpG island |
lots of Cs followed by lots of G's that blocks transcriptional machinery |
|
|
histone acetyl transferases |
transfers acetyl groups to the histone to mask the positive charge |
|
|
histone deacetylaces |
take off acetyl groups and wind up the DNA, the tails then bind and block the DNA |
|
|
shRNA |
pairs with mRNA and RISC (RNA interference silencing complex) to chew up RNA that needs to be destroyed |
