The autonomic nervous system helps in regulating some processes which are without a person’s conscious effort. Some of these processes are breathing rate, blood pressure. The autonomic nervous system is divided into two parts- sympathetic and parasympathetic. In general, the sympathetic part prepares the body for an emergency situations such as sight or flight, whereas, the parasympathetic controls body process during normal situations.
Sympathetic part is at work in these situations:
- Ross feels nervous because he misplaced his important work documents.
- Dory sees a bear while hiking in the woods, and her heart rate increases.
- Rodrigo’s breathing increases when he hears a scary sound.
Parasympathetic part is at work in these situations:
- Maya feels her heart rate slow down after strenuous exercising.
- Sofia’s muscles relax when she finds her missing cell phone.
- Lisa feels calm after yoga class.
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.[1][2]
In a cell, DNA replication begins at specific locations, or origins of replication, in the genome.[3] Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis. Most prominently, DNA polymerasesynthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase.
DNA replication can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to initiate DNA synthesis at known sequences in a template DNA molecule. The polymerase chain reaction (PCR), a common laboratory technique, cyclically applies such artificial synthesis to amplify a specific target DNA fragment from a pool of DNA.
