Protein synthesis Flashcards
How is the nucleus involved in synthesising proteins?
DNA is transcripted to mRNA and it leaves through the nuclear envelope.
How is the rough ER involved in synthesising proteins?
Proteins are made on the ribosomes in the rER which are moved from the rER where it turns into a 3D shape on the way.
How is the does the protein move from the rER to the Golgi apparatus?
A vesicle is pinched off the rER and moves to the Golgi
How is the Golgi apparatus involved in synthesising proteins?
The Golgi modifies the proteins by folding it or adding carbohydrates or lipids
How is the does the protein move from the Golgi apparatus to the plasma membrane?
Part of the Golgi is pinched off into a vesicle and goes to the plasma membrane
How is the plasma membrane involved in synthesising proteins?
The vesicle fuse with the plasma membrane to release the proteins by exocytosis
What is DNA?
The macro molecule that contains genetic information and is used to code for proteins
What is a chromosome?
Structures of coiled and condensed DNA
What is a gene?
A section of DNA that contains the complete sequence of bases to code for a protein
What is a codon?
A three-base sequence of DNA or RNA that codes for an amino acid
What is an anticodon?
A sequence of nucleotides that are complementary to the codon
What is translation?
The process in which the complementary code carried by the mRNA is translated by the tRNA into amino acids
What is transcription?
The process in which mRNA is made from a DNA template
What is mRNA?
A short strand of RNA produced from transcription from the sense strand. It has uracil instead of thymine
What is tRNA?
Molecules that act as temporary carriers of amino acids bringing the correct amino acid to the correct part of RNA based on the mRNA
