Document Summary

Synthesis always start with atg for dna (reading frame) An insertion or deletion of a single base pair will cause a frameshift. When it occurs in the beginning of the sequence, it can lead to a completely non-functional protein. A from the dna will bind with u from the rna and. G is still binding with c like in the dna: rna polymerase, similar to the dna polymerase, makes the rna nucleotides that will bind with the dna template strand. It also needs to know when to start. In dna replication, dna polymerase will know from the origins of replication. In transcription, the rna polymerase will know from a particular sequence of dna called the promoter (rich in a"s and t"s). The first nucleotide of the rna transcript is referred to +1 and the start site is where the rna starts to be made.
