Study Notes
- Cells in the body make proteins through gene expression, involving transcription and translation processes.
- Nucleic acids like DNA and RNA play a crucial role in this process, with nucleotides containing a sugar, phosphate group, and nitrogenous base.
- DNA is a double-stranded helical molecule with adenine, guanine, cytosine, and thymine bases, while RNA is single-stranded with uracil instead of thymine.
- DNA serves as the molecule of heredity passing on genes for making RNA and proteins in the body.
- Transcription starts in the nucleus, where RNA polymerase uses DNA to create messenger RNA (mRNA) by linking nucleotides based on complementary base pairing.
- Translation takes place in the cytoplasm on ribosomes, where mRNA is decoded to build proteins by aligning transfer RNA carrying specific amino acids based on codons.
- The ribosome functions as a ribozyme, linking amino acids together with peptide bonds to form proteins like amylase, which are then processed and secreted for specific functions like digesting starch.
