1.True Statements:

Binding of the large ribosomal subunit is the end of the initiation stage.
The third base of a codon permits wobble pairing
There are three stages;initiation,elongation and termination

Transcription factors are proteins that controls the rate of transcription of genetic information from DNA to mRNA,by binding to a specific sequence.

Charged tRNAs enter A site prior to be added to the protein chain.

Translation can be regulated globally (for every mRNA) in the cell through changes in the availability or activity of the helper proteins.

2.Restriction Enzymes

They are used to cut DNA at specific sequence.

(DNA polymerase are used to produce multiple copies of a gene in Polymerase Chain Reaction,Next gen sequencing describes a DNA sequencing technology where entire human genome can be sequenced in a single day,Hi stone acetylase alters accessibility of chromatin and allows DNA binding proteins to interact with exposed sites to activate gene transcription and downstream cellular functions.)
