Nationalism means the belief of groups of people who are bound by cultural, territorial and ethnic. The answer is A. Centripetal forces. These are forces in a state promoting stability, unity and giving the strength thus binding a state together such as having strong national culture.
C. Is the answer love....
The correct option to this question will be 'C' i.e., Gorilla Gorilla.
As the number of Differences of the amino acids representing for the beta-haemoglobin is less than other 5 species from humans, so we can say that Gorilla is closely related on the basis of molecular data given in the question. The beta Haemoglobin Gene is responsible for coding a protein which is called beta-globin. Each cell present in humans contains two genes of beta-globin.
Answer:
Watson and Crick proposed the double helical model of DNA.
Explanation:
- This model says that DNA exist as double helix. It has two polynucelotide strands running in opposite direction i.e the strands are anti-parallel.
- Each polynucleotide strand is made up of several nucleotide liknked together by phophodiester bonds.
- The two strands are not coiled upon each other but the double strand is coiled upon itself around a common axis like the spiral stair case. Here base pairs forms the stairs and backbone of two strands form railing. Back bone contains sugar and phosphate.
- The base pairing is specific, adenine always pairs with thymine and guanine always pairs with cytosine. Thus if we see any base pair, it consists of one purine and one pyrimidine.
- The two strands of DNA thus show complementary base pairing.
- The strands are held together because of hydrogen bonding between the bases in opposite strand.
- One full helical turn involves ten base pairs and the base pairs are stacked 3.4 A apart.
- This form is called as B-form of DNA.
