Explanation:
These questions are related to the extraction of DNA using detergents and ethanol.
1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.
2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.
3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.
4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.
5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.
5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
The answer should be RNA but i think DNA would work too
Unicellular definition- A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. In contrast, even the simplest multicellular organisms have cells that depend on each other to survive.
Multicellular definition- Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms.
Prokaryote definition- A microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria. In a few organisms called prokaryotes, there is no defined nucleus and the DNA is found throughout the cell.
Eukaryote definition- A eukaryote is an organism whose cells contain a nucleus within a membrane. Eukaryotes vary from single-celled organisms to complex multicellular animals and plants. In fact, most living things are eukaryotes, made up of cells with distinct nuclei and chromosomes that contain their DNA.
Autotroph definition- An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. Green plants, algae, and certain bacteria are autotrophs.
Heterotroph definition- A heterotroph is an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are secondary and tertiary consumers.
Hope this helps..
