Jul 18, 2020 · Definition. Protein synthesis is process in which polypeptide chains are formed from coded combinations of single amino acids inside the cell. The synthesis of new polypeptides requires a coded sequence, enzymes, and messenger, ribosomal, and transfer ribonucleic acids (RNAs). Protein synthesis takes place within the nucleus and ribosomes of a ...

Protein synthesis is the creation of proteins. In biological systems, it is carried out inside the cell. In prokaryotes, it occurs in the cytoplasm. In eukaryotes, it initially occurs in the nucleus to create a transcript (mRNA) of the coding region of the DNA. The transcript leaves the nucleus and reaches the ribosomes for translation into a prote...
The term protein came from Late Greek prōteios, prōtos, meaning “first”. The word synthesis came from Greek sunthesis, from suntithenai, meaning “to put together”. Variant: protein biosynthesis. Forum Question: Where does protein synthesis take place? Best Answer!
Proteins are a major type of biomolecule that all living things require to thrive. Both prokaryotes and eukaryotes produce various proteins for multifarious processes and functions. Some proteins are used for structural purposes while others act as catalysts for biochemical reactions. Prokaryotic and eukaryotic protein syntheses have distinct diffe...
In biology, a codon refers to the trinucleotides that specify for a particular amino acid. For example, Guanine-Cytosine-Cytosine (GCC) codes for the amino acid alanine. The Guanine-Uracil-Uracil (GUU) codes for valine. Uracil-Adenine-Adenine (UAA) is a stop codon. The codon of the mRNA complements the trinucleotide (called anticodon) in the tRNA.
mRNA, tRNA, and rRNA are the three major types of RNA involved in protein synthesis. The mRNA (or messenger RNA) carries the code for making a protein. In eukaryotes, it is formed inside the nucleus and consists of a 5′ cap, 5’UTR region, coding region, 3’UTR region, and poly(A) tail. The copy of a DNA segment for gene expression is located in its ...
Following protein synthesis are events such as proteolysis and protein folding. Proteolysis refers to the cleavage of proteins by proteases. Through it, N-terminal, C-terminal, or the internal amino-acid residues are removed from the polypeptide. Post-translational modification refers to the enzymatic processing of a polypeptide chain following tra...

Secondary structure: regularly repeating local structures stabilized by hydrogen bonds. The most common examples are the α-helix, β-sheet and turns. Because secondary structures are local, many regions of different secondary structure can be present in the same protein molecule.

Apr 21, 2023 · Definition: codons. A sequence that comprises three DNA nucleotides that together code for a protein; provide encoding instructions for the addition of one amino acid to a protein or indicating that the protein is complete. Figure 3.3.3 3.3. 3: Translation of mRNA into an amino acid.
Jan 30, 2023 · The Protein Synthesis Machinery. In addition to the mRNA template, many molecules and macromolecules contribute to the process of translation. The composition of each component may vary across species; for example, ribosomes may consist of different numbers of rRNAs and polypeptides depending on the organism.
It begins with the sequence of amino acids that make up the protein. Instructions for making proteins with the correct sequence of amino acids are encoded in DNA. Figure 9.4.1 9.4. 1: Transcription and translation (Protein synthesis) in a cell. DNA is found in chromosomes.
