Scientists have successfully cloned animals, including mammals such as sheep. Which statement provides the most likely reason th
tigry1 [53]

Answer:

4) Some people consider human genetic experiments

unethical.

Explanation:

1) Humans have DNA that is structurally very different from

other mammals.

2) Cloning can only he performed on animals that normally

reproduce asexually.

3) Human genes are made of too many different types of

simple sugars.

4) Some people consider human genetic experiments

unethical.

The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.

<em>Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.</em>

<em>Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.</em>

<em>Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.</em>

The correct option is 4.

Q2.1 - Hydrogen bonds can form with bases on the opposite DNA strands in the double helix, or between the bases and H2O in the s
Natali [406]

Answer:

Explanation:

In the  structure of  Nucleic acids the nucleobases (nucleotide and bases) are arranged is  a specific  form.This form of arrangement is called Base stacking.It simply refers to the bond formed between the adjacent bases.

These nitrogenous bases of (A,T,C.G) pairing  in DNA are in planes in geometry.The bases planes stack  with one another.This form of arrangement  give rooms for more Van der Waals interactions in the plane of the bases.Although the Van der Waals are weak interactions,the bond ensure that these bases are braided or twisted together to give maximum energy,to maintain stability of the bases,and therefore of DNA structure

Therefore in water  and other aqueous solution the stability of  structure of DNA is enhanced by the base stacking,(coiling or twisting)with maximum van der waals interaction  among the bases, than the hydrogen  bonds formed between bases.Generally there are more stacking among G-C,than A-T,thus the former pairing contribute more the structural stability than the latter (A-T)

2. What is an example of something studied on the molecular level (as opposed to the atomic level)?
Dmitriy789 [7]

Answer:

Something studied on the molecular level is the water.

Explanation:

Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.

The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.

With respect to other options:

  • <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
  • <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
