Tumour cell genes
Suggest a way methylation may affect tumour cell genes.
Methylation pattern between tumorous and normal tissue
Outline the difference in methylation pattern between tumorous and normal tissue samples.
DNA methylation
DNA methylation has a critical role in gene regulation by affecting transcription. Samples were taken from two colon cancer tumors (T1 and T2) and two normal colon samples (N1 and N2). A particular gene was implicated as a possible cause of cancer. The promoter of this gene was cloned (A–J). The data show the DNA …
DNA coding
DNA has regions that do not code for proteins. State two functions of these regions.
Mitotic index of tissue
Outline what is indicated by the mitotic index of tissue taken from a tumor. [50 marks]

Compare and contrast the structure of a typical prokaryotic cell with that of a mitochondrion. [40 marks]

The impact of energy drinks on the blood pressure and heart rate of people
I am an HL biology student so I need it to be more AdvanceThe research question is:– What is the effect of energy drinks on the heart rate, and systolic and diastolic blood during resting.– Is there a statistical difference in blood pressure and heart rate between male and females consumer and non-consumers.I will include …
