Asexual=no PARENTS, I've been cloned; never died!
Fusion of hydrogen nuclei (isotopes deuterium with tritium) into helium
complementary Fission needs to replicate DNA - this is also FISSION, clone!
chromosome How do your DNA get replicated? CHROMOSOME has 1 or 2 chromatidis!
chromatids Get DNA model - it is open! "Sister" is a clone! DNA packaging: histones and nucleosomes (HHMI)
karyotype Evolution of human chromosome #2: why do humans have 46 chromosomes, other great apes have 48? Apes 48 chromosomes, common ANCESTOR! #2 has 2 centromeres from chimp #13, stop@3:15
chimp, gorilla, gibbon, bonobo evolution science?
homologous alleles is from meoisis movie; preview haploid.
sexual_cycle BRING MARKERS for CHICKEN or egg, NAVEL orange conjoined twin. PEANUT buckeye embryo. Split seedless BANANA naked? Seedless Watermelon: triploid Colchicine tricks!
sex-determination This is preview of MEIOSIS. XYY normal! Men nipples? On autosome, sweat/sebaceous glands. SRY not in Phelan.
X and Y HOMOLOGOUS -> cross-over & recombine. How many copies of a gene? 4. Meiosis, crossing over, and the SRY gene: XX males and XY females (HHMI) Everything You Never Knew About Sex 10:50 "Why do men have nipples?"
cell_cycle This is true CYCLE tho cell splits into 2 CLONES.
Interphase is 1-3 of figure, then condense karyotype: M, C.
Revu
checkpoints Note Mitosis is M + C here. M checkpoint at metaphase: 3 strikes, or 3 passwords.
cancer Cancer formation: abnormal cell division (HHMI)
mitosis Revu no cell plate.
mitosis-anaphase Review Q: 4 sets of chromosomes.
mitosis-telophase Spindle apparatus is disassembled.
mitosis-metaphase meta=beyond/higher-level: metadata; change: metabolism/morphosis; physics: Aristotle book after "physics". Spindle fibers attach to kinetochores on opposite sides of the centromeres.
meiosis DO anaphase MATCHING exercises #2 - chromosomes have 2 chromatids, crossing over=Meiosis I.
SKIP spermatogenesis/oogenesis for LAB only.
meiosis_I SAY recombination. Metaphase I: random align -> independent assortment!
meiosis_II Meta II: no longer sister chromatids due to X-over!
spermatogenesis Sertoli: hormones.
oogenesis You can call oocyte an EGG? Which is used In-Vitro Fertilization?
2M primary oocytes prophase I @ birth, 28 days. 300-400 ovulated/life; Corpus luteum secretes progesterone.
independent Assortment exercise: just reverse the last B/b pair
crossing_over Random, multiple points. Play Y Evolution after NEXT chap: DNA evolves: genotypes -> phenotypes. Evolution of Y chromosome over 300 million years: are the X and Y really homologous? (HHMI)
allele_diversity Binary=base 2, exponent 2=1 pair ! 240=1 trillion combos, 50=quadrilltion. World population 7.4 billion.
nondisjunction Extra chromosome is the dark/light GREEN pair. Meiosis II animation: audio only
aneuploidies Turner X blank, XO. XX males and XY females: crossing-over; OY is fatal.
PAINT XYY: metaphase II Calico cat and X inactivation: random deactivation of an X chromosome
Calico=halloween orange/black/white can be XXY male!
trisomy Today Show: many DOWN develop Alzheimer: amyloid-beta on 21 Link Between Down Syndrome and Alzheimer's Disease: chromosome 21 has 250 genes

7ePost: 1=c 2=F 3=b(A grana not wrong) 4=A(green!) 5=a
6=F(ATP already made in light) 7=F(caretenoids "capture" energy?)
8=D(photosystem act as antenna) 9=a 10=F (NADPH made in Photosystem I)
11=b 12=F (1%)? 13=F 14=A 15=b
16=b 17=A 18=F 19=d 20=B o not absorb green (but what is green filter?)
