central dogma of molecular biology 1

• ribosomes is made of rrna and proteins, it have 2 subunits( large and small ) that joins during a peptide synthesis
• mrna is produce in transcription, it contains genetic infos from the dna that is use for protein synthesis in translation
• trna: anticodon, bilingual because it has amino acid on the one side and 3 bases on the other side
• when amino acids chain up, it is because of the covalent bond
• all organisms share the same genetic code "unity of life"
• there are 64 anticodons but there are only 20 amino acids
• it's normal for codons to share amino acids, but it's not when a codon produces more than 1 a.a
• codons can be start or stop codons
• genetic infos can be written in 4 dna bases
• 3 bases specify an amino acid found in protein molecules
• message in dna is transcribed and will be translated into a protein
• trna is twisted and bonded
