HNRS 1007 Lecture Notes - Lecture 10: Genital Wart, Endoreduplication, Meiosis
Document Summary
Binary fission in bacteria: chromosome replication begins, replication continues, replication finishes, two daughter cells result. Endoreduplication: repeated cycles of chromosome duplication without nuclear or cell division. Arabidopsis thaliana (single cells become huge due to endoreduplication: once cells are committed to endoreduplication, they will not switch back to normal replication- simply cease replicating after about 5 rounds of replication. 130 strains cause warts, cancers: most common sexually transmitted infection, gardasil vaccine protects against. 2 strains responsible for 70% of cervical cancers. 2 strains responsible for 90% of genital warts: almost every human being has some strain of hpv in them or on them (only the. In bacteria: no organelles--- all occurs in one space, two factors. In eukaryotic: no sigma--- instead several factors, cycle. Eukaryotic pre-mrna: occurs in nucleus, processing. Fragments must have a cap and tail (otherwise, cell treats it like a virus) trna: anticodons. Determines which amino acids can bind: aminoacyl-trna synthetase.
