Both DNA and RNA are synthesized by covalently linking a nucleoside triphosphate to the previous nucleotide, constantly adding t
o a growing chain. In the case of DNA, the new strand becomes part of a stable helix. The two strands are complementary in sequence and antiparallel in directionality. What is the principal force that holds these two strands together
Hydrogen bonding is very essential for life on earth. DNA has a double-helix structure that means it has two distinct strands in its structure and hydrogen bonds hold together the nitrogen base pairs in the middle. In absence of hydrogen bonds, DNA would have to exist as a different structure. The principal force or bonds between those two strands are Hydrogen bonds between the nitrogen bases. Adenine always makes a hydrogen bond with Thymine whereas Guanine always binds with cytosine.
The answer is : <span>There seems to be no evidence of </span>sexual dimorphism (sexes alike). The Cuban greater funnel-eared bat (Natalus Primus) have no evidence sexual dimorphism. Meaning they are <span>monomorphic.</span>
