What is protein synthesis in biology quizlet?
What is protein synthesis in biology quizlet?
Protein Synthesis. The process of making proteins that involves replication , transcription, and translation. rRNA. A type of RNA that associates with proteins to form ribosomes in the cytoplasm.
What are the 5 steps of protein synthesis quizlet?
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 purpose of protein synthesis quizlet?
Purpose: The purpose of DNA replication to make an exact copy of the cells DNA. The purpose of Transcription is to change DNA into MRNA, and the purpose of translation is to produce proteins from mRNA and tRNA.
Why is protein synthesis important quizlet?
Why is protein synthesis important? Without proteins there would be no life. Protein makes up the structure of a cell and also the enzymes which allow for chemical reactions to happen.
What are the 4 main steps of protein synthesis?
The steps are illustrated in the figure below.
- Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter.
- Elongation is the addition of nucleotides to the mRNA strand.
- Termination is the ending of transcription.

What is protein synthesis simple definition?
Definition of protein synthesis noun Biochemistry. the process by which amino acids are linearly arranged into proteins through the involvement of ribosomal RNA, transfer RNA, messenger RNA, and various enzymes.
Which best summarizes the process of protein synthesis?
Which best summarizes the process of protein synthesis? DNA unzips, resulting in the formation of two protein molecules.
How do you explain protein synthesis to a child?
When a cell makes a protein it is called protein synthesis. The instructions for how to make a protein are held in DNA molecules inside the cell nucleus. The two major stages in making a protein are called transcription and translation.
