8.4/8.5 Protein Synthesis

Question 1

What is the protiome?

Answer 1

All proteins expressed

Question 2

What are the steps of protein synthesis?

Answer 2

Transcription
Splicing
Diffusion into cytoplasm
Translation

Question 3

What does DNA polymerase do?

Answer 3

Copies complementary bases

Question 4

Describe transcription

Answer 4

DNA helicase breaks H bonds
Free nucleotides from cytoplasm join to complementary bases
RNA polymerase makes phosphodiester bond for mRNA
H bonds between mRNA and DNA
H bonds breaks between DNA and mRNA and the mRNA moves away
mRNA is spliced to remove introns

Question 5

Which cells has the smaller ribosome?

Answer 5

Prokaryotic cells

Question 6

How does translation work?

Answer 6

tRNA attaches to mRNA codon
Protein is translated
Next tRNA codon joins to next codon
Protein is translated
Peptide bond form between new and previous protein

Question 7

What is required for peptide bonds to form during translation?

Answer 7

ATP
