#20 Biologia 11º ano: Síntese Proteica e Código Genético 🧬
Help2Learn 🇵🇹・2 minutes read
DNA replication and protein synthesis play essential roles in preserving genetic information and regulating cell metabolism, with the genetic code determining amino acid sequences in proteins through transcription and translation. This universal code, encoding 22 amino acids in triplets, involves transcription by RNA polymerase to create mRNA, which is then translated in the cytoplasm by ribosomes to produce proteins.
Insights
- DNA replicates to pass genetic information, leading to protein synthesis through transcription and translation, where the genetic code dictates amino acid sequences in proteins.
- Transcription involves RNA polymerase creating mRNA from DNA, which then undergoes processing to remove non-coding parts before moving to the cytoplasm for translation by ribosomes, ultimately determining protein structure and function.
