Student teams investigate a fictional anthrax case by modeling DNA sequencing and tracking down the "guilty" lab. B. The science behind identifying the suspected lab In the anthrax case, the ...

Within the nucleus of every cell are long strings of DNA, the code that holds all the information needed to make and control every cell within a living organism. DNA, which stands for deoxyribonucleic ...

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each ...

Nucleotides are the fundamental units that make up the genetic material of all living organisms. They are the building blocks of DNA and RNA, which store and transmit genetic information. Nucleotides ...

A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a new ...

An ongoing challenge for researchers who are studying the origins of life is figuring out how biopolymers such as DNA and RNA might have formed in the first place. In the case of RNA, a candidate for ...

Pyrosequencing can be used to detect DNA and RNA from almost any source, and has applications in bacteria resistance screening, drug development, epigenetics, and many other fields. If no light is ...

RNA or ribonucleic acid is a polymer of nucleotides that is made up of a ribose sugar, a phosphate, and bases such as adenine, guanine, cytosine, and uracil. It plays a crucial role in gene expression ...
