Fill in the steps of transcription and translation from protein synthesis. *** Then put a TSC(transcription) or a TSL(translation) on the line next to the corresponding step.

TSC 1. The DNA molecule unwinds.

TSC 2. The mRNA nucleotides attaches.

TSC 3. The mRNA leaves and goes to the Ribosomes.

TSC 4. The DNA rewind/zips back up.

TSL 5. The tRNA gathers the amino acids from the cytoplasm

TSL 6. The DNA assembles the amino acides into a protein!

Explanation:

2. The first codon is being read

i can't see the full page, therefore, can't answer it

explanation:

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
