When DNA was discovered, Watson and Crick saw that the strands of the double helix are lined up in the opposite direction of each other. This type of orientation is called the antiparallel orientation.
The antiparallel orientation is a type of orientation showing two polymers present side by side but running in the opposite direction. The best example of this is the deoxyribo nucleic acid (DNA). DNA molecule is made up of a pair of polynucleotide strands which are antiparallel. The antiparallel orientation of the DNA facilitates the hydrogen bonding between the two complimentary strands. This is also important for the processes of DNA replication and transcription.
The long term effects of competition on populations of two different species competing for the same source are as follows:
1. It becomes a situation of the survival of the fittest. For example, if two populations of plants compete for the same source, the stronger of the two species will overpower the weaker of the two species. Trees that grow taller will block out the sun and the smaller trees will die. In the animal kingdom, the strongest of the predators that compete for the same prey will survive.
C.The unique role the species plays in an ecosystem .
<span>Plants take in oxygen all the time for respiration.
Photosynthesis which begins by combining water and CO2, continues in the
"dark phase" in making the glucose molecule. Light is not used for this
part of the reaction so it is called dark , because light is needed for
the first part.
