Question

visual reading tool: transcription and translation
fill in the missing labels on the diagram of protein synthesis.

Explanation:

Protein synthesis involves transcription (DNA to mRNA in nucleus) and translation (mRNA to protein in cytoplasm). The main components are: RNA - polymerase for transcription initiation, ribosome as the site of translation, t - RNA for carrying amino - acids, and amino - acids that form the polypeptide chain.

1. RNA - polymerase binds to DNA to start transcription.
2. Nuclear pore allows mRNA to exit the nucleus.
3. Ribosome reads the mRNA sequence.
4. mRNA strand being translated.
5. t - RNA with an anticodon that base - pairs with mRNA.
6. Amino - acid chain (polypeptide).
7. Growing polypeptide chain.

1. RNA - polymerase
2. Nuclear pore
