Transcription
DNA → RNA
What direction does RNA synthesis occur in
5’→ 3’
What direction is template ssDNA read in
3'→ 5’
Coding strand different name
Non-template strand
Difference bw coding strand (non-template) and transcribed RNA
exact same except T/U swap
Template strand (non-coding strand) vs transcribed RNA
has reverse complement seq bc used as template. read in 3’ to 5’ so new RNA can be synthesized 5’ to 3’
Gene
region on organism’s genome
CODES INFORMATION to produce protein or functional RNA expressed in a CONTROLLED WAY
2 major components of genes
information to make proteins or functional RNAs
Information to control gene expression
Trasnscirbed region
Gets transcribed to mRNA upon gene expression
Promoter region
Part of the gene that regulates where, when, and how frequently gene gets transcribed
