SOCR 330 Lecture Notes - Caat Box, Ribonucleotide, Side Chain
Document Summary
Identifiable dna sequence coding for a specific product. Structural genes code for proteins rrna, trna genes code for ribonucleotide acids. Promoter upstream from exon (includes tata box and ccaat box) Convert the information encoded by the dna base sequence into molecules (usually proteins) that determine cell properties and function. Replicate itself accurately so encoded information can be passed on. Process of converting information in base sequence to gene product. 1 gene = 1 protein no longer valid. Human cell can make 100,000 proteins but only about 22,000 genes in genome. Amino acids joined by peptide bonds to form a polypeptide. Polypeptide chain modified (folded, spiraled, conjugated etc. ) to make different proteins. Degenerate (more than one codon for same amino acids) Within gene, one dna strand codes (coding strand) and one does not (template strand) (sense & nonsense strands) Which strand is coding vs. template may vary from gene to gene.
