2021年9月23日 · Protein Synthesis involves translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. It is the process in which ribosomes in the cytoplasm or ER synthesize …

2023年2月17日 · Protein synthesis, as the name implies, is the process by which every cell produces specific proteins in its ribosome. In this process, polypeptide chains are formed from varying amounts of 20 different amino acids. It is one of the fundamental biological processes in both prokaryotes and eukaryotes.

2020年7月18日 · 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).

2025年1月22日 · Prokaryotic (70S) and cytoplasmic eukaryotic (80S) ribosomes are each composed of a large subunit and a small subunit of differing sizes between the two groups. Each subunit is composed of rRNA and protein. Organelle ribosomes in eukaryotic cells resemble prokaryotic ribosomes. Some 60 to 90 species of tRNA exist in bacteria.

In eukaryotic cells, chromosomes always remain in the nucleus, but proteins are made at ribosomes in the cytoplasm or on the rough endoplasmic reticulum (RER). How do the instructions in DNA get to the site of protein synthesis outside the nucleus?

A membrane-bound organelle found in eukaryotic cells made up of a series of flattened stacked pouches with the purpose of collecting and dispatching protein and lipid products received from the endoplasmic reticulum (ER). Also referred to as the Golgi complex or the Golgi body.

2024年6月2日 · Here’s an overview of protein synthesis in eukaryotes: The process begins in the nucleus, where DNA is located. The DNA sequence of a specific gene that encodes a protein serves as a template. RNA polymerase, an enzyme, binds to the DNA at the gene’s promoter region and initiates transcription.

Eukaryotic protein synthesis involves more protein components and some steps are more complex. The initiating codon is eukaryotes is also AUG. The eukaryotic mRNAs do not have a purine-rich sequence (ribosome binding sequence) on the 5′ end.

2013年6月24日 · In eukaryotes, with the assistance of the eIF-4 initiation factors, the 40S ribosomal sub unit binds close to a structure called “cap structure” at the 5-end of the mRNA and then moves down the messenger RNA sequence till it finds the initiating codon. However this process requires energy from ATP.

Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures...
