Скачать или смотреть DNA Replication | Translation and Transcription|

DNA replication is the process by which a DNA molecule is duplicated, resulting in two identical copies of the original DNA molecule. It occurs during the S phase of the cell cycle and involves the unwinding of the double helix, complementary base pairing, and the synthesis of new DNA strands using existing strands as templates
Transcription:
Transcription is like making a copy of a recipe from a cookbook. In the cell's nucleus, a molecule called RNA polymerase acts like a chef. It starts by finding the beginning of a gene (like finding the start of a recipe), then it "reads" the gene's instructions (which are in DNA). As it reads, it builds a matching strand of RNA, just like writing down the recipe. Instead of the bases A, T, C, and G found in DNA, RNA uses A, U, C, and G. When the chef reaches the end of the gene, it stops, and we have a complete RNA copy, which is like having the recipe in hand.

Translation:
Translation is like turning that written recipe into an actual dish. This happens outside the nucleus, in a part of the cell called the ribosome, which acts like a kitchen. The RNA copy, called mRNA, is used as a set of instructions. Another molecule, tRNA, acts like kitchen helpers bringing in ingredients (amino acids) one by one. Each tRNA has an anticodon that matches with the mRNA's codon (like matching ingredients with the recipe). As the ribosome reads the mRNA, it tells the helpers (tRNA) to bring the right amino acids and link them together. This process continues until it reaches a "stop" signal in the mRNA, just like finishing a dish. The result is a chain of amino acids, which folds into a functional protein, like a delicious meal
