Study Notes
Transcription
- Transcription is the process of synthesizing RNA from a DNA template, converting genetic information into a form that can be translated into proteins.
- RNA polymerase is the enzyme that catalyzes the transcription process, unwinding the DNA and synthesizing a complementary RNA strand.
Location of Transcription in Eukaryotic Cells
- In eukaryotic cells, transcription occurs in the nucleus, where the DNA is housed.
- After transcription, the RNA transcript undergoes processing before it is exported to the cytoplasm for translation.
Location of Translation in Eukaryotic Cells
- Translation takes place in the cytoplasm, either on ribosomes that are free-floating or attached to the endoplasmic reticulum.
- The process requires mRNA, tRNA, and ribosomes to assemble amino acids into polypeptide chains based on the genetic code.
Role of the Genetic Code in Protein Synthesis
- The genetic code consists of nucleotide triplets called codons, which correspond to specific amino acids during translation.
- It allows for the accurate translation of mRNA into proteins, ensuring the proper sequence of amino acids as dictated by the DNA sequence.
RNA Splicing Events
- RNA splicing is the modification of the pre-mRNA molecule, where introns (non-coding regions) are removed and exons (coding regions) are joined together.
- This process results in a mature mRNA transcript that can be translated into a protein, allowing for diverse protein expression from a single gene through alternative splicing.
