Biosecurity
effective management of risks posed by working with infectious agents and toxins in laboratories. Its goal is to identify and reduce risk before they evolve into neear incidents
Biorisk management
3 components of Biorisk management
Assessment, Mitigation, and Performance

This equipment is used for preparing Mastermix
PCR Cabinet (Reagent preparation room)
It is used for RNA Extraction and Template Addition
Biosafety cabinet class II (Extraction room)
used for the treatment of biohazardous wastes
Autoclave (Doffing area)
What is the principle of autoclave?
Steam under pressure
Thermal cycler is also termed as _______room
Amplification room
2 types of waste generated by molecular laboratory
General waste and Biohazardous waste
TRUE OR FALSE
DNA and RNA are macromolecules comprised of many nucleotides
TRUE
3 parts of a nucleotide
A nitrogenous base, 5 carbon sugar, and 1 Phosphate group
What enzymes unwind the DNA?
DNA helicase
This enzyme is for the synthesis of short RNA primers
RNA primase
adds nucleotides to the primers and extends the strand
DNA polymerase III
degrades the RNA primer and replaces it with DNA
DNA Polymerase I
connect two strands of RNA
DNA ligase
Synthesis of RNA (mRNA) through DNA by RNA polymerase
Transcription
Synthesis of polypeptide/protein through mRNA
Translation
Where does translation happen?
in the ribosomes
