Translation/Protein Synthesis
100
Segments of DNA formed during replication; form the lagging strand
What are Okazaki fragments?
100
Direct product of transcription before processing
What is pre-mRNA?
100
Coding region found in mature mRNA that leaves the nucleus
What is an exon?
100
Transcribed region before the start codon or after the stop codon
What is the untranslated region (UTR)?
200
DNA region where RNA polymerase binds but is not transcribed
What is a promoter?
200
Non-coding sequence removed during RNA splicing
What is an intron?
200
Multiple ribosomes translating one mRNA simultaneously
What are polyribosomes?
300
Proteins that bind enhancers and form a protein bridge to increase the rate of transcription
What are transcriptional activator proteins?
300
mRNA modification made to the 3’ end
What is the poly A tail?
300
mRNA that codes for multiple proteins under a single regulatory region
What is polycistronic mRNA?
400
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?
400
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?
500
Complex that removes introns from pre-mRNA
What is a spliceosome?
