Listed below are steps in the transcription process. Reorganize the list so the steps in the correct order- starting with the first step in initiating transcription and ending with completion of a new strand of RNA (in other words- from start to finish of transcription).
RNA polymerase reaches the termination signal
DNA unwinds underneath RNA polymerase at transcription start site
RNA polymerase is recruited to the promoter region
mRNA transcript is released
General Transcription factors bind TATA box (and other DNA sequences) in the promoter region
General Transcription Factors unbind from promoter region
mRNA transcript synthesis occurs
RNA polymerase moves along the template strand in the 3’ to 5’ direction
Match the term to its best definition.
molecule with high-energy bond that carries
amino acid to translation site
part of a gene that gets translated into a protein
primary transcript in eukaryotes that needs to be
processed
single stranded nucleic acid that helps both in
transcription and in splicing
nucleic acid that makes up 50% of each ribosome
sequence of DNA upstream from the gene that
binds RNA polymerase before transcription
post processing molecule that carries instructions
for making a protein from the nucleus to a
ribosome in the cytoplasm
part of a gene that gets spliced out during pre
mRNA processing
Why will a mistake in the RNA code alone not become a mutation?
