Question

1. place the following molecules in order of their use during the process of protein synthesis. (dna, trna, polypeptide, mrna, amino acid) 1st __________ ________ ________ ________ __________ last

Explanation:

Step1: Recall Protein Synthesis Steps

Protein synthesis has two main parts: transcription and translation. First, DNA is used as the template to make mRNA (transcription). Then, during translation, mRNA is read, tRNA brings amino acids, and amino acids are linked to form a polypeptide.

Step2: Order the Molecules

1st: DNA (since it holds the genetic code and is the starting template for transcription).
2nd: mRNA (transcribed from DNA, carries the code to ribosomes).
3rd: tRNA (brings specific amino acids to the ribosome based on mRNA codons).
4th: Amino acid (delivered by tRNA, used to build the polypeptide).
5th (Last): Polypeptide (the final product of protein synthesis, formed from linked amino acids).

Answer:

1st: DNA
2nd: mRNA
3rd: tRNA
4th: Amino acid
Last: Polypeptide
