Okazaki fragments finishing up replication, what must occur? any nicks remaining and all the Okazaki fragments must be ligated (joined) the whole DNA fragment is transcribed... true or false... if false, what is not transcribed? false, there is a promoter sequence to start, then the introns need to be spliced out what is post-transcription process? when the introns are spliced out rRNA forms ribosomes rRNA asks like a(n) in the ribosome enzyme tRNA each bring their own ____ ____ to the site to see which one fits the codon (triplet of bases) amino acid
