Lect 3 - Cell Anatomy (DNA)

Question 1

Process of Creating Proteins

Answer 1

DNA undergoes transcription to create RNA which undergoes translation to become Protein

Question 2

Where does transcription occur

Answer 2

Nucleus

Question 3

Where does translation occur

Answer 3

Cytoplasm

Question 4

Transcription Process

Answer 4

RNA polymerase binds to promoter to initiate transcription

DNA is split

RNA polymerase joins free nucleotides and pairs them with DNA nucleotides

Completed mRNA is then transported through nuclear pores into the cytosol

Question 5

Translation Process

Answer 5

mRNA binds to small ribosomal subunit

mRNA and tRNA are lined up by initiation factors

Large ribosomal subunit binds and initiation factors dissociate

Peptidyl transferase on large ribosomal subunit successfully adds a.a. according to mRNA template

Termination sequence is reached and peptide is released

Question 6

Rough Endoplasmic Reticulum

Answer 6

Has ribosomes
Produces, folds, and controls quality of protein

Question 7

Smooth Endoplasmic Reticulum

Answer 7

Synthesizes lipids, sterols, and hormones
Detoxification
