Answer to: (a) Compare and contrast DNA and RNA. (b) Discuss why humans did not evolve with 1 central repository of DNA, but rather it is...

"The first thing we did was to ask whether there was evidence that evolving cooperation is a two-step process," Botero said. "We found that the most likely ancestral birds bred and lived in pairs, so we wondered if birds didn't first evolve the ability to maintain family groups, and on...
He was the first to propose the five kingdom taxonomic classification of the world's biota into the Animalia, Plantae, Fungi, Protista, and Monera in 1969. Do viruses have DNA? Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-...
When was the first animal on earth? These clusters of specialized, cooperating cells eventually became the first animals, which DNA evidence suggests evolvedaround 800 million years ago. What was the first cell on earth? The first cells were most likely verysimple prokaryotic forms. Ra- diometric...
Viruses are microscopic organisms that require a living cell, often called a host, to multiply. They largely consist of genetic material (either DNA or RNA)wrapped in a protein coat. These DNA and RNA sequences may change over time, accumulating modifications to the genetic code that favour th...

orRNA. This is a far simpler and more essential molecule than the more famous deoxyribonucleic acid, orDNA, that defines how we are put together. But RNA is still orders of magnitude more complex than the kinds of chemicals one tends to find floating around in space or stuck to the face...
These newly formed RNA molecules then guide Cas9 to the aforemen- tioned sequence (Cas9 being a nuclease responsible for cleaving the DNA). One of the leaders in synthetic CRISPR reagent development is Syn- thego. With Synthego's online tool, scientists can easily design such RNA reagents ...
