TAMU bio 111 lab exam 2 review (2023/2024) already passed What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription. 
What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can...

For e. coli , the lacl repressor gene is expressed when? The lacl repressor gene is always 
expressed 
 
Where does the lacl repressor gene attach The lacl repressor gene codes for a protein which 
attaches to the lac operon operator 
 
In the absence of lactose, does the lacl repressor gene bind to DNA Yes, in the absence of 
lactose, the lacl repressor gene binds to DNA preventing transcription; this is an example of 
negative...

CBE 235 FinalLac Operon - correct answer -involved in heating lactose: inducible operon 
1) The lactose repressor protein coded by Lacl bound to the operator tightly near the mRNA start site, blocking the ability of RNA poly to bind 
2) Lactose introduced--> Lac repressor binds to lactose and changes conformation such that it can no longer bond to the operator 
3) RNA poly can access the promoter and transcription goes 
4) LacZ,LacY,LacA are transcribed
