Core Promoter Elements 
 ~~> TATA box = repetitive sequence of thymine and adenine 
 Initiator (INR) = sequence of pyramidines like thymine and cytosine 
 DPE = downstream promoter elements found along the DNA 
Common to have >1 promoter but not all of them 
CpG islands 
 ~~> Sequences high in CG frequency. They are able to escape 
methylation which would lead to gene silencing. Demethylation would 
lead to over expression of genes. 
Regulatory Promoter Elements 
 ~~> UAS and URS f...

Describe the phylogeny of GRs? - ️️Bees. 
Only about 350 to 400 ORs. Ants have the record for ORs. 
Unlike honey bees, actually expansion in GRs (also true of Nasonia). Bees lost this shit, down to like 12. 
Basic pathway of RNAi - ️️1. double stranded RNA is recognized by an enzyme, dicer and cleaved into short piece abotu 21 bp long 
2. These 21 bp long sections are recognized by a complex of proteins called RISC (RNA induced silencing complex) which uses them to recognize perfectly m...

CRISPR Based Genome Engineering 
Exam Questions With Verified Answers. 
What is CRISPR - answerThis is a technology that research scientists use to selectivelt 
modify the DNA of a living organism. CRISPR was adapted for use in the lab from natually 
occurnig genome editing systems which are found in bacteria. This technology allows for precise 
modifications to the genetic code, offering the potential to treat various medical conditions by 
editing genes responsible for certain diseases
