fundamental review 2 Flashcards
what is transcription?
the process by which dna is making RNA
what is translation?
the process by which proteins are coded for RNA
what protien is responsible for dna synthesis?
dna polymerase
how accurate is dna synthesis?
it is very accurate, only with a few errors per cell
how does the dna polymerase monitor for abnormalities?
there is a proofreading polypeptide present in the polymerase
what does this proofreading polymerase do for the gene sequence?
it can allow the wrong base to be excluded
what comes first, transcription or translation?
transCription
(remember that c comes before l in the alphabet)
does DNA need a primer to begin replication
yes it does need a primer
what enzyme does transcription?
the RNA polymerase
how many strands of DNA acts as the template for transcription?
just one strand
after translation, does the new sequence remail attatched to the strand of DNA?
no, it does not. after a few pairs, the strand of dna is deplaced by the polymerase
is transcription or or less accurate than dna replication?
less accurate. there is more space for abnormalities
what is the general process of transcription?
the rna polymerase binds to the dna, it elongates, then it terminates
what is translation?
when mature RNA is made into protein
does translation take minimal or a lot of energy?
it takes a lot of energy and is very taxing on the cell
