Predictions for Genetics? (1 Viewer)

[louielouiee]

There is a similar post regarding communication, however I thought I should make one concerning the genetics option seeing as it is just as popular.

Moving on, what do you think will be asked in this option? I'm most concerned about the big 6/7 markers at the end.


2006:
Gene expression (5 marks)
Advancements in our understanding of genetics have changed our understanding of how an organism functions ( 7 marks)

2007:
Humane genome (7 marks)

2008:
Linked Genes & Mutations (6 marks)
Holistic response on understanding health & disease (7 marks)

2009:
Protein Synthesis (5 marks)
Linked Genes Model (6 marks)
Gene therapy & Mutations (7 marks)

2010:
Gene cloning & Cascades (7 marks)

2011:
Human genome project (6 marks)
Holistic response on technologies used to determine relationships between species (7 marks)

I reckon it will be similar to the 2006 question

I think it's pretty hard to predict seeing as the questions have been heaps varied in previous years. They've pulled questions from every part of the syllabus, with the only repeats being linked genes and human genome.

I think they might have a thourough protein synthesis question

I would love if it was cloning, or a broad one on reproductive technology

 

[louielouiee]

Broad questions are difficult! Although it's broad, its still 7 marks and they kinda expect you to zone in on a specific point and explain it in detail, whilst referencing others.

I'd love one on DNA fingerprinting

DNA fingerprinting is not a big enough syllabus topic. However, you may be on to something as they don't do fingerprinting usually, so maybe it might be like 4 or 5 marks?

Yeah it was a 5 mark question in my trial this year! (my school wrote the option as we hadn't covered it entirely yet)

I'd would absolutely hate one on gene expression, I find it hard to grasp. It's not looking to good either seeing as it hasn't been asked since 2006.

I'm fucked if it's focussing on anything in the major dotpoint 8 (or whatever the last one is)
Like, no matter how many times I read over my notes, textbooks/ do a question, I can never get the concept of the HOX genes and stuff like that

 

[louielouiee]

I had to read that quite a few times...
I just remember that Hox genes are regulatory genes (switching genes on and off) which thus control morphogenesis

 

[ohexploitable]

PCR steps (denaturation, annealing, elongation, hold +explain these and give temperature details)
components of PCR (taq polymerase, buffer, MgCl2, DNA template etc.)

 

[ohexploitable]

lac operon (detailed knowledge, effects of mutations on various genes and initiation sequences)

 

[louielouiee]

I use the trp-operon for gene expression. I suppose it doesn't exactly matter as long as you know one in detail.
Or should you know both?
