Study Notes
DNA Transcription & Translation
- Transcription: The process of copying a gene's DNA sequence into messenger RNA (mRNA).
- mRNA (messenger RNA): A single-stranded RNA that encodes genetic information essential for protein synthesis.
- rRNA (ribosomal RNA): A key component of ribosomes, essential for the synthesis of proteins.
- Ribosome: Cellular structures where protein synthesis occurs, translating mRNA sequences into amino acid chains.
- Translation: The process in which mRNA directs the synthesis of a specific protein at the ribosome.
- tRNA (transfer RNA): RNA that transfers and delivers specific amino acids to the ribosome during protein synthesis.
- Uracil: A nitrogenous base exclusive to RNA, pairing with adenine, unlike thymine found in DNA.
- Central Dogma: The principle that genetic information flows from DNA to RNA and then to proteins, defining the pathway of genetic expression.
- Codon: A sequence of three nucleotides in mRNA that specifies a particular amino acid for protein synthesis.
- Anti-codon: A set of three bases on tRNA that pairs with the complementary codon on mRNA, ensuring the correct amino acid is added.
- Amino Acids: The basic building blocks of proteins, linked together to form polypeptides.
- Polypeptide: A long chain of amino acids formed through peptide bonds, which fold into functional proteins.
- Protein: A complex polymer made from sequences of amino acids, performing numerous biological functions.
- RNA: A single-stranded nucleic acid containing ribose sugar, vital for protein synthesis and genetic coding.
- DNA: A complex molecule containing genetic instructions found within chromosomes, serving as the hereditary material.
- Methionine: The amino acid represented by the start codon (AUG), marking the beginning of protein synthesis.
