Steps of Protein Synthesis

What are the steps involved in Protein Synthesis?

1. mRNA leaves the nucleus with the DNA code, and goes to the ribosomes
2. ribosomes make proteins
3. mRNA and tRNA meet in the ribosomes
4. DNA temporarily unzips
5. mRNA nucleotides match up to DNA

Answer:

Protein synthesis follows the following order: DNA unzips, mRNA nucleotides match up to DNA, mRNA leaves the nucleus and goes to the ribosomes, mRNA and tRNA meet in ribosomes, and ribosomes make proteins.

Protein synthesis is a fundamental process in which cells build proteins. This process involves several steps, starting from the genetic information in the DNA and ending with the production of proteins.

1. DNA temporarily unzips

During protein synthesis, the DNA molecule temporarily unzips to expose its genetic information.

2. mRNA nucleotides match up to DNA

Messenger RNA (mRNA) nucleotides align with complementary DNA nucleotides during transcription, forming a sequence that carries genetic information to the ribosomes.

3. mRNA leaves the nucleus with the DNA code, and goes to the ribosomes

After transcription, mRNA molecule carries the genetic code from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.

4. mRNA and tRNA meet in the ribosomes

mRNA matches with transfer RNA (tRNA) in the ribosomes, allowing the correct amino acids to be assembled in the protein chain.

5. Ribosomes make proteins

Ribosomes are the cellular machinery responsible for translating the genetic code carried by mRNA into a sequence of amino acids that form proteins.

Understanding the steps of protein synthesis is crucial in comprehending how cells produce specific proteins essential for their functions.
