Question

Which of the following is NOT a hallmark of cancer?

		Ability to stimulate growth of blood vessels to provide nutrients to the rapidly growing tumor.
		Ability of cells to inhibit cell division when conditions are not optimal.
		Resistance to signals that slow cell division or promote death.
		Metastasis, which allows invasion of local tissues.
		Cell division in the absence of growth signals.

A ribosomal RNA gene is an example of which type of DNA sequence in eukaryotes?

		long interspersed elements
		unique-sequence DNA
		moderately repetitive DNA
		short interspersed elements
		highly repetitive DNA

Answer 1

Answer – (b) Ability of cells to inhibit cell division when conditions are not optimal.
Explanation- Other than this, all options are hallmarks of cancer. The only statement which is not a hallmark of cancer is the above-explained options. Cancer cells can divide and develop into h tumor. It doesn't inhibit the cell division.
Answer – (c) A ribosomal RNA gene is an example of moderately repetitive DNA.
Explanation- It is because moderately repetitive DNA are those which consist of 150-300 nucleotide.

Thank you.
