In the nucleus, enzymes make a RNA copy using a portion of DNA. The RNA is then transformed into a messenger RNA. This is kind of like how a boss would give his coffee order to his intern (the nucleus being the office)
Chromosomes are the thread like structures in the nucleus that carry genetic information in the form of DNA. First, the gene is transcribed, making an RNA copy of itself that is next translated to make a protein. This gene is made up of alleles. Therefore DNA holds the instructions for making genes like this book holds the instructions for all the different drinks that the barista can make for the boss.
Translation is preformed by ribosomes after the transcribed mRNA enters the cell's cytoplasm. Translation begins when a ribosome attacthed to an mRNA moleucle. As each codon passes through the ribosome, tRNAs bring the proper amino acids into the ribosome. One at a time, the ribosome then attached these amino acids to the growing chain. This is similiar to how the intern repeats the order to the barista since the order is being said for the 3rd time.
Each tRNA molecule carries just one kind of amino acid. Also, each tRNA molecule has three unpaired bases, collectively called anicodon. All these different bases that mix to become different protiens are like all the different foods that mix to become one order.
Ribosomes are the places in whcih protien synthesis takes place like how the kitchen is the location in which cooking takes place. The ribosomes form rRNA whcih assemle other protiens together, The ER packages the protiens and sends them to the Golgi Bodies. Here, they are modified and later sent off outside of the cell where they can preform their fuctions like the coffee issent out of the kitchen and brought to the drinker.
Amino acids are then joined together to make a protein like the man and his breakfast is joined together to make one happy boss!!!
