Students today we're going to continue on with our discussion about over the chapter on controls over genes and we're going to be completing the sentence so the sentence reads a nucleotized sequence that signals the start of a gene is a what a promoter and operator and a enhancer or an activator you guys can pause the video if you guys want to take the chance to to answer one question.

Okay, if you've finished answering a question, we'll go in a little bit more about the nucleotized sequence, which is basically a secession of faces signified by a series of a set of five different letters that indicate the order of nucleotized, forming alleles within a dna or rna molecule.

So based off of the basis that you would see, which one would you think would signal for the gene to start? would it be the enhancer, the activator, operator, or promoter? well, i think really hard about this.
01:28
And if you answered a, then you are correct.
01:34
If not, i took the liberty to write down each of them, so that way you guys can remember which is which.
01:43
So a promoter for the dna sequence is usually situated in the upstream of the gene, and it usually signals for the start of the transcription.
01:55
An operator is a short sequence of the dna that's situated close to a promoter region and is recognized by a repressor protein.

So remember, it represses...
