Describe the process of translation and transcription during protein synthesis?

Transcription is the rewriting of information from DNA to mRNA. A certain part of the DNA unwinds and mRNA is built from one of the strands using the DNA polymerase enzyme. The resulting mRNA molecule through the pores of the nucleus enters the cytoplasm, ribosomes are strung on it and a polysome is formed.
Translation – translation of information from a sequence of nucleotides to mRNA to a sequence of amino acids in a protein molecule. During translation, a functional center acts on the ribosome, on which there are 2 mRNA codons, 2 tRNA anticodons, complementary to them, at the end of which there are 2 amino acids, between which a peptide bond occurs. The first tRNA leaves the ribosome, the first amino acid moves from the donor site to the acceptor site. The entire formed complex moves forward, from acceptor to donor, the first codon leaves the ribosome, and the third codon enters the acceptor site. Opposite it is the anticodon of the new tRNA, which carries a new amino acid, and a peptide bond is again formed between the amino acids. The process continues until a stop code for mRNA arrives at the ribosomes.
