Mitosis and Meiosis

[yazza]

does anyone know what we are required to do under this topic besides know what each stage is and does? and are there questions on this every exam? has anyone got a practice sac on this as well? thanks

From what I remember it is good to know about mutations, genetic variability in Meiosis (independent assortment, crossing over).

are there questions on this every exam?

Not sure about other company exams but this ALWAYS appears in VCAA exams.

has anyone got a practice sac on this as well?

Unfortunately we are not allowed to be sharing copyrighted materials on AtarNotes. Though I suggest you just gather Mitosis and Meiosis question from exams and put them all together.

This is from the study design:

Key knowledge
• cell reproduction:
– binary fission in prokaryotes
– the phases of the cell cycle in eukaryotes including DNA replication, the division of the nucleus
(mitosis), and cytokinesis
– the key events that result in the production of haploid sex cells from a diploid cell (meiosis),
including recombination
• molecular genetics:
– the nature of genomes, genes and the genetic code
– gene expression: the genetic code and roles of RNA in transcription, RNA processing in
eukaryotes, and translation
– the concept of gene regulation (the switching on and off of genes by factors expressed by
regulator genes and environmental factors)
• DNA tools and techniques: gel electrophoresis; DNA amplification; DNA sequencing; making a
recombinant plasmid; bacterial transformations; DNA profiling; gene cloning; and using plasmids
as gene delivery systems
• inheritance:
– the nature of chromosomes, alleles, genotype and phenotype
– the causes of phenotypic variation: mutations; recombination of parental alleles in sexual
reproduction; polygenes; and interactions of environmental factors with genes
– continuous and discontinuous variation
– patterns of inheritance involving the monohybrid cross: dominance; recessiveness; co-dominance;
multiple alleles
– dihybrid crosses as independent or linked
– pedigree analysis: autosomal and sex-linked inheritance; use of the test cross.

The examiners are always very keen to see you use your knowledge in context. No doubt there'll be question that merely ask you to recall facts (as dictated by the study design above), however, for high achieving students, they want to see a demonstration of that knowledge used in context. Quite often, exam questions will describe a situation and will ask you to comment on whether or not two organisms may be able to breed, possible reasons for a genetic disease or et cetera. You'll get the best idea from looking at exams, but these type of questions require you to recall the knowledge and then use it. It gives you the opportunity to do some scientific sleuthing. So it's paramount that you understand each stage, but also understand the importance of each stage. You need to be able to describe what can go wrong, and, in terms of the science, why that causes an anomaly. It's not just enough to be able to blurt out information on biol—you need to be able to use that information!

thanks for the reply guys, appreciate it!
