E7

Question 1

What is a gene

Answer 1

Section of DNA that directs the synthesis of one or more overlapping mature RNA molecules

Question 2

What is a start codon

Answer 2

Determines the reading frame ( Aug, encoding Met)

Question 3

What is a stop codon

Answer 3

Ends the reading frame
UAA
UAG
UGA

Question 4

Translation process

Answer 4

RNA makes protein
Messenger RNA contains the code
Transfer RNA is the decoder
Ribsomal RNA links the amino acids

Question 5

Initiation ( first step of translation)

Answer 5

Finding the start codon and assembling the ribosome with the first tRNA

Question 6

Elongation

Answer 6

Coupling amino acids from tRNA to a growing peptide chain

Question 7

Termination

Answer 7

Recognising the stop codon and releasing the new protein

Question 8

Aminoacyl tRNA binding

Answer 8

Codon recognition

Question 9

Peplidy transfer

Answer 9

Peptide bond formation

Question 10

Translocation

Answer 10

Moving to the next codon

Question 11

Antibiotics that target bacterial protein synthesis

Answer 11

Tetracycline, streptomycin, chloraphenical

Question 12

what are the 4 Basie synthetic genetic processes

Answer 12

Replication, transcription, RNA processing and translation

Question 13

What is replication

Answer 13

DNA synthesis by coping the existing DNA

Question 14

What is transcription

Answer 14

RNA synthesis by coping if DNA

Question 15

RNA processing

Answer 15

Modification of RNA in the nucleus and the cytoplasm

Question 16

Translation

Answer 16

Protein synthesis by decoding of RNA
