Question

Label the steps for protein synthesis in order, beginning with the first step

Answer 1

The steps for protein synthesis in order are:

1. Copy of one side of DNA strand is made (called mRNA, messenger RNA)

2. mRNA moves to cytoplasm, then ribosome.

3. mRNA goes through ribosome 3 bases at a time.

4. transfer RNA (tRNA) matches up with the open DNA bases.

5. tRNA releases the amino acid at the top, which joins the chain of amino acids being produced.

Answer 2

Steps of protein synthesis:

1) DNA double helix unwinds into a single strand and exposes a sequence of nitrogenous bases, this is also known as the unzipping process.

2) Transcription: In this process, DNA transfer the genetic instruction to mRNA in the nucleus.

3) Translation: In this process mRNA couples the ribosomes & tRNA helps to bring amino acids to ribosomes. This process is known as Initiation.

4) Elongation: Anti-codons present on tRNA recognizes codons present on mRNA.

5) Termination: In this step when the stop signal on mRNA is reached, the process of protein synthesis is terminated.
