Document Summary
Lecture outline: prokaryotic transcription, diversity of rna structure & function. It is program which aligns multiple sequences to each other. It requires input sequences to be fasta format. It will align any sequences together, even those chosen at random from sequence databases. It uses algorithm which inserts gaps to maximize alignment score. How the dna information is used for the synthesis of rna. Transcription is 1 of the cellular processes. Already talked about process of dna replication & how it replicates itself in a cell. In a cell, the dna gets transcribed into rna rna is essentially an intermediate between dna & protein. Single stranded mrna is translated to a protein sequence which then folds into its tertiary structure. Electron micrograph showing transcription in the cell. All the feathers/hairs coming off of dna molecule are transcripts being generated by rna polymerases each 1 of dots are rna polymerases with emerging transcript coming off of it.
