What are the 5 steps for protein synthesis?

Terms in this set (5)

  • Unzipping. – DNA double helix unwinds to expose a sequence of nitrogenous bases.
  • Transcription. A copy of one of the DNA strand is made.
  • Translation (Initiation) mRNA couples w/ ribosome & tRNA brings free amino acids to ribosomes.
  • Elongation. – Anticodon of tRNA recognizes codon on mRNA.
  • Termination.

What is the first step in the synthesis of a protein?

The first step of protein synthesis is called Transcription. It occurs in the nucleus. During transcription, mRNA transcribes (copies) DNA. DNA is “unzipped” and the mRNA strand copies a strand of DNA.

What are the major steps in protein synthesis?

It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.

What is another name for protein synthesis?

Translation

What is another name for a protein chain?

Another name for a protein chain is polypeptide chain. The basic building block of proteins are amino acids, which are small organic compounds.

What is a protein a chain of?

Proteins are built as chains of amino acids, which then fold into unique three-dimensional shapes. Bonding within protein molecules helps stabilize their structure, and the final folded forms of proteins are well-adapted for their functions.

What is the best definition of protein?

The definition of a protein is a substance that has amino acids, compounds and carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and is found in many foods. An example of a protein is the type of nutrient found in meats. Proteins play a central role in biological processes and form the basis of living tissues.

What are the examples of protein?

What are proteins examples?

Examples of proteins include whole classes of important molecules, among them enzymes, hormones, and antibodies. Proteins are one of the three types of nutrients used as energy sources by the body, the other two being carbohydrate and fat.
