2

A gene on chromosome 17 codes for the p53 protein.

Select from the drop-down menus to correctly complete the sentence.

After the gene is __________ into mRNA the mRNA is __________ to produce the p53 protein.

2

A student created a model of a DNA sequence and its mRNA transcript, as shown.

RNA  5'- TCG GCA TAG- 3'

Another student found a mistake in the model
Select from the drop-down menus to complete the sentence describing the correction that should be made to the model.

The __________ nucleotides in the mRNA transcript should be replaced with __________ nucleotides

1

In cancer cells, mutations in the DNA cause the cells to reproduce uncontrollably, forming a tumor. Cancer directly affects which cellular process?

1

Which of the following is a primary reason for cancer cells developing in an organism?

1

Which of the following is the correct sequence of events in the creation of a protein?

1

Methylation is a process that can add methyl (CH3) groups to DNA. A gene containing methylated nucleotides often cannot be transcribed. As a result, proteins will not be produced. Which of the following cellular processes is most directly affected by DNA methylation?
