Question

place the steps for the formation of the enzyme pepsinogen in the correct order.
the dna strands unwind, and rna polymerase binds to the template strand.
the trna undergoes intron splicing and exits the nucleus.
the trna moves through mrna with the activated amino acids attached to it.
the synthesis of mrna begins.
the amino acids assemble to form peptide.

Explanation:

This is the correct sequence of gene expression (transcription then translation) for making the protein pepsinogen:

1. Transcription initiation: DNA unwinds and RNA polymerase binds.
2. mRNA synthesis proceeds from the DNA template.
3. mRNA is processed (intron splicing) and leaves the nucleus.
4. tRNA matches mRNA codons to amino acids in translation.
5. Amino acids link to form the pepsinogen peptide.

Answer:

1. The DNA strands unwind, and RNA polymerase binds to the template strand.
2. The synthesis of mRNA begins.
3. The RNA undergoes intron splicing and exits the nucleus.
4. The tRNA moves through mRNA with the activated amino acids attached to it.
5. The amino acids assemble to form peptide.
