Segments of DNA formed during replication; form the lagging strand
What are Okazaki fragments?
Direct product of transcription before processing
What is pre-mRNA?
Coding region found in mature mRNA that leaves the nucleus
What is an exon?
Transcribed region before the start codon or after the stop codon
What is the untranslated region (UTR)?
DNA region where RNA polymerase binds but is not transcribed
What is a promoter?
Non-coding sequence removed during RNA splicing
What is an intron?
Multiple ribosomes translating one mRNA simultaneously
What are polyribosomes?
Proteins that bind enhancers and form a protein bridge to increase the rate of transcription
What are transcriptional activator proteins?
mRNA modification made to the 3’ end
What is the poly A tail?
mRNA that codes for multiple proteins under a single regulatory region
What is polycistronic mRNA?
Added to 5’ end of primary transcripts, involved in translation initiation; binds translation initiation factors and recruits ribosomal subunit
What is the 5’ guanine cap?
Complementary sequence found on the 3’ end of the 16S RNA in the small ribosomal subunit (bacterial), involved in translation initiation
What is the Shine-Dalgarno sequence?
Complex that removes introns from pre-mRNA
What is a spliceosome?
