Study Notes
Key Concepts in Protein Synthesis
- Genes: Segments of DNA that encode information to produce proteins, influencing traits like eye color.
- Protein Synthesis: The biological process where DNA is translated into proteins, crucial for various cellular functions.
Proteins and Their Functions
- Proteins: Essential macromolecules involved in numerous functions such as transportation, structural support, enzymatic activity, and immune protection. Vital for life.
DNA and RNA
- DNA: Found in the nucleus, serves as the blueprint for all genetic information.
- RNA: Transports genetic information from the nucleus to the cytoplasm, facilitating protein production.
Transcription Process
- Transcription: The process of converting DNA into an RNA message, occurring in the nucleus.
- RNA Polymerase: Enzyme that catalyzes the formation of RNA by linking RNA bases to complementary DNA bases.
mRNA and Ribosomes
- mRNA (messenger RNA): A type of RNA that carries genetic information from DNA to ribosomes in the cytoplasm for protein synthesis.
- Ribosome: Cellular machinery composed of ribosomal RNA (rRNA) that synthesizes proteins during translation.
Translation Mechanism
- Translation: The phase of protein synthesis where the mRNA message is decoded to form a specific protein.
- tRNA (transfer RNA): Molecules that transport specific amino acids to the ribosome, matching them to the corresponding codon on the mRNA.
Codons and Anticodons
- Codon: A sequence of three nucleotide bases on mRNA that specifies a particular amino acid during translation.
- Anticodon: A complementary sequence of three bases on tRNA that pairs with a codon on mRNA; for example, UAC pairs with AUG and carries the amino acid methionine.
Codon Chart
- Codon Chart: A tool used to identify which amino acid corresponds to a specific codon, aiding in understanding the genetic code.
Peptide Bonds
- Amino Acids from tRNA: These building blocks of proteins are linked together by peptide bonds during the translation process, forming polypeptide chains.
