  • Distance from the moon [detail level=0.6]

This article is about the average distance from the Earth to the Moon.
In astronomy, a lunar distance (LD) is a measurement of the distance from the Earth to the Moon.
The average distance from Earth to the Moon is 384,400 kilometers (238,855 miles).[1] The actual distance varies over the course of the orbit of the moon, from 356,700 kilometres (221,600 mi) at the perigee and 406,300 kilometres (252,500 mi) at apogee.
High-precision measurements of the lunar distance are made by measuring the time taken for light to travel between LIDAR stations on Earth and retroreflectors placed on the Moon.
The Moon orbiting Earth, sizes and distances to scale.

  • DNA [detail level=0.4]

Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses).

 

  • DNA [detail level=0.6]

Deoxyribonucleic acid  (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses).
The DNA segments carrying this genetic information are called genes.
Likewise, other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
This information is read using the genetic code, which specifies the sequence of the amino acids within proteins.

 

  • DNA [detail level=0.8]

The structure of part of a DNA double helix .
Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses).
The DNA segments carrying this genetic information are called genes.
Likewise, other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
Along with RNA and proteins, DNA is one of the three major macromolecules that are essential for all known forms of life.
DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds.
This information is read using the genetic code, which specifies the sequence of the amino acids within proteins.
