the synthesis of RNA using informaiton in the DNA.
Term
mRNA
Definition
code for proteins
Term
rRNA
Definition
form basic structure of the ribosome/catalyze proten synthesis
Term
tRNA
Definition
assential to protein systhesis/ adaptors to mRNA and amino acids
Term
Similarities in DNA & RNA
Definition

-use DNA template

- read 3'-5'

-write 5'-3'

 

Term
Promotor
Definition
sequence in the DNA recognized by the RNA polymerase as a signal to begin transcription
Term
Terminator
Definition
sequence in DNA recognized by RNA polymarase as a signal to end transcription
Term
Capping
Definition

- 7 methylguanosine

-added to 5'of mRNA

-added to RNA as it is released from DNA during transcription

Term
Splicing
Definition

- editing out DNA sequence

- not all genes are spliced

-occurs as RNA is released from DNA during transcription

-inscrasing incoding capacity
