Bio 1201 Gregg exam 3 questions and answers rated A+ the units of heredity and are made up of segments of DNA genes how many chromosomes do humans have in the nucleus of their somatic cells? 46 chromosomes (23 pairs) the two chromosomes in each pair are called... homologous chromosomes/homologs each pair of homologous chromosomes includes... one chromosome from each parent what does meiosis result in 4 haploid daughter cells what does meiosis 1 do separates homologous chrom...

Cell division in which the nucleus divides into nuclei containing the same number of chromosomes Mitosis The resting phase of mitosis. Cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases Interphase Cells that have left the cycle and cease dividing for a long time (or permanently) G Zero (G0) Phase The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins. G1 Phase T...

GENETICS FINAL EXAMS| GENETICS TEST BANK|415 QUESTIONS WITH 100% CORRECT ANSWERS| LATEST UPDATE 2024|2025 - Crossover or DNA recombination occurs in eukaryotes between non-sister chromatids during prophase of meiosis Recombination also occurs between prokaryotes (via conjugation) and as a means of viral integration into a host cell The molecular mechanisms of crossover differ by species, but always in- volves the exchange of DNA between adjacent chromosomes These mechanisms are still the...

IB Biology: Chapter 1.6 Latest Update Graded A cell cycle all stages in the life cycle of a cell interphase composed of G1, S, and G2; = the growth of the cell. G1 - DNA transcription - protein synthesis (centrioles) - cell Respiration (produces energy) - growth of cell volume - organelles double (mitochondria & chloroplast) -increase in energy stored G0 the stage where cells are unlikely to divide (ex: neurons) S - synthesis of genetic material - DNA replication - dup...

AP Biology Questions and Answers (Graded A) The resting membrane potential depends on which of the following? I. Active transport II. Selective permeability III. Differential distribution of ions across the axonal membrane A. III only B. I and II only C. II and III only D. I, II, and III D The resting potential depends on active transport (the Na+K+-ATPase pump) and the selective permeability of the axon membrane to K+ than to Na+, which leads to a differential distribution of ...
