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.
You would predict that indoleacetic acid, a plant hormone, would have is a Auxin.
A chemical known as indoleacetic acid (IAA) is produced by plants and a few microorganisms (3, 4). IAA is important for both root and shoot growth in plants. By means of an efflux pump (PIN1-7) and a specified importer (AUX1), the hormone travels from one area of the plant to another (5, 6).
Auxin mainly help in complex mechanism of a plant , which lead many metabolic activities in plant .
What is Auxin ?
- Auxin plays a crucial role in controlling plant growth and development by regulating embryonic development, root and stem tropisms, apical dominance, and the transition to blooming.
- It is used to start off shoot growth in culture and encourages lateral and accidental shoot growth.
- Aids in overcoming auxin-induced apical dominance.
- Encourage the development of leaves' chloroplasts.
- Encourages the mobilization of nutrients and delays leaf senescence.

significant digits are certain digits that give detail in a number
ex. in the number 400 it is the 4 because it tells you how many hundreds are in the number, in the number 49.92 it would be all of them because they all help understand the number
Do you get it?
Answer:
The options are not given but the correct way to write the scientific name of pea plant is- Pisum Sativum and P. Sativum
Explanation:
Binomial nomenclature is the method which is used to name any organism. It includes two parts a genus part and species part. According to binomial nomenclature, The name of the genus should be written first and then the species name.
The first letter of the genus name should be in capital and rest all letters should be in small letters. The species name should start from small letter and the genus and species name should be italicized.
If handwritten the genus and species name should be underlined separately. Therefore according to the rule, the right way to write pea plant scientific name is Pisum Sativum and P. Sativum.
