BISC 101 Lecture Notes - Lecture 7: Hydrolysis, Intellectual Disability, Phenylalanine Hydroxylase
Document Summary
Bisc 101 lecture 7 from gene to protein. Joins the 3" end of the dna that replaces the primer to the rest of the leading strand. Joins the okazaki fragments in the lagging strand. Rna molecule: occurs in nucleus of eukaryotes, occurs in cytoplasm in prokaryotes, rna polymerase is used to make an mrna molecule. The tail facilitates the export of mrna out of the nucleus and into the cell cytoplasm. Protects mrna from degradation by ribonucleases: splicing out introns and joining of exons. Exons only: exons: code for proteins, expressing sequences, an rna transcript should only consist of exons. Translation: process of converting information stored in nucleic acid sequences into proteins, major players of translation, mrna (messenger rna, trna (transfer rna, ribosomes, amino acids. Genetic code: code is almost universal, it is used both by prokaryotes and eukaryotes, codon: each group of 3 nucleotides on the mrna. 64 possible codons, but code for only 20 different amino acids.
