cancer

Question 1

how does a competitive inhibitor work?

Answer 1

binds to active site

Question 2

what does decrease methylation mean?

Answer 2

transcription factors can bind so RNA polymerase can bind and catalyse phoshodiester bonds of mRNA

Question 3

Describe how alterations to tumour suppressor genes can lead to the
development of tumours.

Answer 3

-mutation is tumpur supressor gene
-change to sequence of amino acid, changing tertiary structure
- uncontrolled cell division as non functioning proteins produced

Question 4

what is epigenetic

Answer 4

1. Heritable changes in gene function;
2. Without changes to the base sequence of DNA;

Question 5

what are transcription factors made from ?

Answer 5

protein

Question 6

Explain how increased methylation could lead to cancer.

Answer 6

added methylgropus to cytosine base OF TUMOUR SUPRESSOR GENE
tightly coils so transcription factor and RNA polymerase cannot bind
mRNA is not transcribed or translated
uncontrolled cell division

Question 7

describe how you would plot a scatter graph

Answer 7

put left column on x axis and right column on y axis and do a sitter graph due to DISCRETE DATA
