Question

From government sources looking at millions of women, the overall chance of devleoping ovarian cancer is actually quite low, about 1%. That means about 99% of women will never develop ovarian cancer. [THIS IS TRUE] The fact that you know you have relatives in your family tree that have died of ovarian cancer doesn't change (have any impact) on this overall chance.

True

False

Mutation in a gene can hae a wid variety of effects on the protein it encodes. It could result in a protein with no function, some function, and even a protein that functions within the range of normal!

True

False

You don't synthesize insulin in your big toe, even though there are two copies of the insulin gene in every cell of your body (except certain cells of your ovaries and testes, as we will see later). That's because basic gene structure not only contains the rules for how to make the protein, but also the rules for "when," "where," and "how much" of the protein to make. These rules make up the "promoter" of the gene.

True

False

Explanation / Answer

The answers are as follows:

A1) False, as this increases the chance of having the cancer since it can occur based on the genetic makeup of the organism which is inherited.

A2)True, all of these effects are possible

A3) False, it is not a promoter as it is also present in every cell of the body but it is the methylation of the gene that stops its transcription and hence translation into the protein.
