What is DNA protein synthesis?
What is DNA protein synthesis?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
What is the meaning of protein synthesis?
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.
What is DNA RNA and protein synthesis?
The Central Dogma of Molecular BiologyDNA makes RNA makes proteins. The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
How does DNA direct protein synthesis?
Thus, the synthesis of a protein is governed by the information in its DNA, with the help of messengers (mRNA) and translators (tRNA). In the nucleus, DNA is transcribed to RNA. The mRNA carries the message out of the nucleus to the ribosome in the cytoplasm where the tRNA helps translate the message to make a protein.
How DNA regulates protein synthesis?
1 Answer
- DNA regulates protein synthesis by coding for the specific sequence of amino acids in a protein.
- This control is possible through transcription of m-RNA.
- Genetic code is specific for particular amino acid.
Where is protein synthesis?
Ribosomes are the sites in a cell in which protein synthesis takes place.
How DNA replication and protein synthesis occurs?
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
What is the synthesis of DNA and RNA?
The syntheses of RNA (transcription), DNA and proteins (translation) are fundamental processes necessary for all life. Transcription begins by uncoiling a section of DNA that will be used as the template and is initiated by RNA polymerase binding to a promoter sequence.
What is the role of DNA and RNA in protein synthesis quizlet?
DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.
What are the steps from DNA to protein?
(A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.
What is the function of protein synthesis?
The purpose of protein synthesis is simply to create a polypeptide — a protein made out of a chain of amino acids.
