The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).
On the off chance that there is an EcoR1 site in either the center of the Glo quality, or amidst the selectable marker site in the plasmid, it would likely debilitate either Glo, or the plasmid.I hope this will help.

Answer:
<em>In a pedigree, a vertical line and a bracket connect parents to their children.</em>
Explanation:
A pedigree can be described as a diagram which depicts the lineage of a person and shows his/her ancestors in a pattern. A pedigree is very helpful in understanding any genetic disorders which occur in a family. It helps the doctor conclude that whether the parents will have the probability of having a normal child or not.
In a Pedigree, a vertical line will be drawn to show the parents and their children. A horizontal line is drawn between the parents.
