What is the chemical formula for nucleotides?
Adenine Base Pyrimidines are single 6-atom rings. The purines are adenine and guanine. The pyrimidines are cytosine, thymine, and uracil. The chemical formula of adenine is C5H5N5. Adenine (A) binds to thymine (T) or uracil (U).
What are the 4 base chemicals in DNA?
DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
What are the 4 nucleotides of DNA?
So each DNA molecule is made up of two strands, and there are four nucleotides present in DNA: A, C, T, and G. And each of the nucleotides on one side of the strand pairs with a specific nucleotide on the other side of the strand, and this makes up the double helix.

Can we live on Titan?
Habitability. Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.
What are the benefits of colonizing Mars?
What are the Benefits of a Mars Colony?
- Mars is the most accessible planet in the solar system.
- Exploring Mars may possibly answer origin and evolution of life questions.
- Mars could someday be a destination for the survival of humankind.
- There is the possibility of discovering new life that could impact life on Earth.
What are the risks of going to Mars?
These hazards—space radiation, altered gravity fields, isolation and confinement, closed environments, and distance from Earth—are linked with over 30 human health risks as documented by NASA’s Human Research Program.
Is going to space dangerous?
The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.
