Gamete sex cell - Study guides, Class notes & Summaries

oogenesis correct answers formation of the female gamete - sex cell - eggs in suspended stage of cell division - just before the second meiotic division (2nd division is associated with fertilization) - shed throughout life (number reduces) - aneuploidy increases with age (ovarian hormonal function decreases with age - chromosomal abnormailitiy) how is aneuploidy is affected by environmental factors correct answers other new studies have suggested that the meiotic errors (aneuploidy) ar...

Alzheimer's disease- chronic neurodegenerative (loss of structure, function, and potentially death of neurons) disease - memory loss - result of deregulated apoptosis, as apoptosis itself leads to programmed cell death cancer- result of uncontrolled cell proliferation Parkinson's disease- neurodegenerative (loss of structure, function, and potentially death of neurons) disease - motor control loss - cell atrophy & death --> apoptosis Turner Syndrome- aneuploidy (specifically a ...

BIOL 2300: Exam 3 Quiz Questions with Complete Solutions The most common aneuploidy seen in living humans has to do with ___________. Sex Chromosomes Mammals with multiple X chromosomes undergo random X-inactivation in each nucleus early in gestational development. This results in only one X chromosome being active in each cell, no matter how many X chromosomes are present.Which sex chromosome genotype(s) would you expect not to express Xist RNA? XY A boy with Klinefelter syndrom...

HSC Biology Module 5 Reproduction Reproductive success The ability to produce fertile offspring that survive to reproductive maturity and produce offspring of their own. Biological fitness the measure of an individual's reproductive success. It is calculated as the average contribution to the gene pool made by a certain genotype within a population and the relative likelihood that these alleles will be represented in future generation. Sexual reproduction It involves the meet...

Transcription - DNA to make RNA; the strand of DNA transcribes the RNA with A & U and C &G together; when DNA is transcribed (in the nucleus), the result is an RNA molecule; genetic information is transferred from DNA to RNA; DNA together then RNA polymerase comes in and separates the double helix and the RNA is made; initiation--> elongation--> termination DNA replication - copying mechanism bringing appropriate nucleotide to daughter DNA molecule; strands meeting int he middle; maki...

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 ...
