Discovery of the Sixth DNA base?

Scientist has described the possible existence of sixth DNA base, the methyl-adenine (mA) this week.

Deoxyribonucleic acid (DNA) is a polymer of nucleotides, which encodes every genetic information of living existence. The entire genetic information are stored within DNA as the form of millio... Read More

Designer viruses for killing tumor cells

A major goal of viral oncotherapy – the use of viruses to destroy tumors – is to design viruses that kill tumor cells but not normal cells. Two adenoviruses provide perfect examples of how this specificity can be achieved.

Adenovirus CG0070, designed to treat bladder cancer, and adenovirus O... Read More

Freshman Biology Creative Projects
