Protein Synthesis

Question 0

2- transcription

Answer 0

(Production of Mrna molecules according to the dna code, location-nucleus)
Complementary rna bases bond with exposed dna
Enzyme- rna polymerase joins bases together forms Mrna

Question 1

1- Initiation

Answer 1

Enzymes in nucleus unwind double helix shape of dna

Question 2

Transcription

Answer 2

(Production of protein according to certain dna code)
Mrna goes to cytoplasm
Rrna found in ribosomes
Mrna and rrna join in small ribosome subuinit (site of p.s)
Trna attracted to mrana
Anticodon in trna complementary to mrana’s codon
After stop codon trana begins attatch to mrna
Amino acids detach from trna to form new oritein
When stop codon reached protein released

Question 3

Mrna

Answer 3

Carries: Start codon
Series of codons
Stop codon
Made in transcription , nucleus

Question 4

Trna

Answer 4

Transfer rna 
Found in cytoplasm 
Carries:
Anticodon 
Particular amino acid

Question 5

Site of protein synthesis

Answer 5

Small ribosome subunit

Question 6

Amino acid and p.s

Answer 6

Amino acids detatch from trna
Oeptide bonds form between them
Moves out of ribosome
Folds into its 3d shape so it can properly function
