SEHS 12: Genetics

Here's the video of the unit presentation:

12.1.1

1

What is the primary function of chromosomes?

Secreting hormones

Carrying genetic information

Regulating body temperature

Producing energy

1

What is the purpose of DNA replication in cell division?

To create new cells

To repair damaged DNA

To produce energy for the cell

To pass on genes to new cells

12.1.1

null

You only need to cover:

DNA Replication
Chromosome
DNA Polymerase (group)

You could cover lagging and leading strands but you're unlikely to need that detail.

1

Which of the following is true of DNA replication?

Each strand of DNA in the double helix serves as a pattern for duplicating the sequence of bases.

DNA replication creates new types of DNA molecules.

DNA replication ensures that each daughter cell has a complete set of genetic information.

DNA replication eliminates excess DNA from the cell.

DNA replication occurs in the mitochondria.

12.1.1

null

A bit like:

"Climate is what we expect, weather is what we get". We could say:

"Genotype is what we expect, phenotype is what we get"

Try covering each word then each vertical pair (6 boxes in total)

1

Which characteristics are expressed developmentally by genes only?

VO2max

Height

Sex

Eye color

12.1.1

null

Try covering both "characteristics" and grouping them. Then cover the examples.

1

Genes code for the production of ________ which are responsible for the development of an individual.

carbohydrates

proteins

vitamins

lipids

12.1.2

null

For Transcription and Translation you could try 5 boxes in total:

2 leaving the T and N visible
2 covering the whole word
1 covering both words
As long as you choose "hide 1 guess 1", there will only be 1 in play at a time.

How genes can influence human characteristics:
Genes can be switched on or off depending on ________ factors (gene regulation).

internal or external

genetic

parental

psychological

12.1.2

null

Cover as you like. My suggestions:

turned on and off

gene regulation

athletic performance

12.1.2

null

12.1.2

null

1

How genes can influence human characteristics:
Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription. What is transcription?

When the information in a gene’s DNA is transferred to protein

When the information in a gene’s mRNA is transferred to DNA

When the information in protein is transferred to mRNA

When the information in a gene’s DNA is transferred to mRNA

1

Multiple genes determine measurable characteristics, so it is ________ a single genetic element is associated with athletic performance.

possible

definite

highly unlikely

probable

1

Characteristics that are influenced by genetics
Environmental factors that also influence performance

12.1.3

null

12.1.3

Don't block out the whole word. Leave enough to give yourself a clue but force some thinking.

null

1

Training maximizes the likelihood of obtaining a performance level with a genetically controlled ceiling.

It is possible to scientifically ascertain the relative contribution of genetics or training to elite sporting performance for a variety of sports.

2

Identify two possible benefits of genetic screening in shot put.

1

Identify one possible drawback of genetic screening in shot put.

12.1.4

0

The syllabus also asks you to be aware of:
ethical implications of involuntary exclusion from, or discrimination in, one or more sports
ethical implications of discrimination beyond sport, for example, in employment
What do you think this means?

Outline how characteristics of an elite basketball player can be influenced by their genes.

In the hint, you will find the mark scheme and examiners' report.
It is important that you try to answer this before checking the mark scheme. If you find it uncomfortable, that's great! Sometimes learning hurts a bit!

1

Which term is defined correctly?
This is a nice question to spend a bit of time investigating the alternative options.
In fact, I'll tell you what - the answer is C. There you go, easy! Now, we could click C and move on, but we don't improve our chances in the final exam with that. Try to use it as an opportunity to discover more.
For example, here's a link to show why the answer in A is weird!
Move on when you're happy you understand why the answer is C

How can genes influence human characteristics?
