PROPHASE I Flashcards
chromosomes begins to condense and appear as long and thin threads. On PROPAHASE I
LEPTOTENE
HOMOZYGOUS CHROMOSOMES PAIR WITH EACH OTHER.
ZYGOTENE
PACHYTENE
WHERE CROSSING OVER OR EXCHANGE OF CHROMOSOMES
CHROMATIDS CONTINUE TO SHORTEN AND THICKEN AND THE SYNAPTONEMAL COMPLEX STARTS TO DISINTEGRATE
DIPLOTENE
CHROMOSOMES BECOME SHORTER AND THICKER DUE TO CONDENSATION.
DIAKINESIS
A GENETIC CONSEQUENCE WHRE BLANK REDUCES NUMBER OF CHROMOSOME FROM DIPLOID TO HAPLOID SO CHROMOSOMES NUMBER OF SPECIES IS MAINTAINED.
MEIOSIS
DERIVED FROM PRIMORDIAL GERM CELL.
OOGENESIS
ER, GOLGI APPARATUS, MITOCHONDRION
G1 PHASE
PREPARING FOR CELL DIVISION
INTERPHASE
SYNTHESIS OF DNA AND HISTONE AND DUPLICATION OF EACH chromosome. AMOUNT OF DNA DOUBLES
S PHASE
BIOCHEMICAL EVENT NECESSARY FOR THE CELL HAPPENS IN THIS PHASE.
G2 PHASE
CHROMOSOMES CONDENSE AND BECOME VISIBLE.
PROPHASE
ACTIVE CELL DIVISION WHICH INCLUDES MITOSIS AND CYTOKINESIS.
M PHASE
