You are here. The Planets in Natural Colors. Several teachers and students have asked what the planets look like in true or natural colors. They've noticed that each planet's appearance can vary greatly in photographs, and that many of the photographs are labeled as a false-color view. Many times scientists enhance the colors, or contrast of an image to draw out more detail.
A critical feature of DNA is the ability of the nucleotides to make specific pairs: . Adenine pairs with Thymine and Cytosine pairs with Guanine. The human genome of Homo sapiens is stored on 23 chromosome pairs. 22 of these are autosomal chromosome pairs, while the remaining pair is sex-determining. The haploid human genome occupies a total of just over 3 billion DNA base pairs that means 6 billion base pairs per diploid cell.
Humans have a total of 46 chromosomes in each body cell; 44 of these are autosomes. You get one set of 22 autosomes from your mom and another set of 22 from your dad. It is often easier to think about our autosomes in pairs because even though we have 44 autosomes, we actually only have 22 types. We have two copies of each type of autosome, one from each parent. Two chromosomes of the same type, called homologous chromosomes, are the same size and shape and have the same genes. Our paired autosomes are numbered 1 through 22.
