binary fission - asexual, usually in prokaryotes origin (of replication) - bidirectional (replication AND separation together) homologous chromosome (homologue) - one from mom, one from dad; similar not identical; same alleles in the same order chromatid; sister chromatid - two IDENTICAL halves of a single replicated eukaryotic chromosome histone - proteins that have DNA wrapped around them in the *nucleosome* structure nucleosome - 147nt of DNA wrapped around a core of 8 histone proteins ...

BIOLOGY 111 EXAM 2 (QUESTIONS & ANSWERS)BIOLOGY EXAM 2 (QUESTIONS & ANSWERS) 1) Carl Woese successfully argued that biologists group living things according to domains rather than kingdoms. He also argued that Archaea and bacteria had to be placed in separate domains because a. Bacteria are polyphyletic, whereas Archaea and Eukarya are monophyletic b. Bacteria and archaea both use fMet as their first amino acid translation during protein synthesis c. They both are prokaryotes d. Only the ar...
