Miles Fritz · Answer 1

The correct order is: B) 2, 5, 4, 3, 1.

2. A segment of DNA is transcribed in mRNA. mRNA is transferred to the cytoplasm. This is the process of transcription that occurs in the nucleus of the cell and it is the first step of gene expression. It is performed by the enzyme RNA polymerase.

5. The mRNA strand is fed through the ribosome. Ribosome is an organelle where protein synthesis (translation) occurs and it consists of proteins and RNAs.

4. Molecule of tRNA delivers amino acids from to the ribosome. tRNA is transfer RNA because of its function to carry amino acids to the ribosomes during protein synthesis.

3. The amino acids are dropped off at the ribosome.

1. The amino acids are joined to make a protein. Amino acids are added to a growing protein chain.
