Unit 4 Protien Sythesis

Question 1

What is the central dogma/process of protein synthesis?

Answer 1

1. Transcription: DNA is copied into a message of RNA

DNA –> mRNA

2. Translation: the RNA message is translated into polypeptides by ribosome

mRNA –> polypeptides

Question 2

What are these
1.mRNA
2. tRNA
3.rRNA

Answer 2

1.mRNA:
Messanger RNA
Copy of DNA message in a RNA strand
= to sense strand bases pairs with anti sense

2. tRNA:
   transfer RNA
   brings animo acids to mRNA to make polypeptides

3.rRNA:
ribosomal RNA
makes up ribosomes
2 sub units ( RNA + protien)
holds mRNA and tRNA together
