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.
A is correct is the answer
Answer:
RNA polymerase creates mRNA when it is is in the starter called Positive transcription factor 5. What does the “mRNA destroyer” do? It destroys the mRNA when there is enough mRna 6. ... Negative transcription doesn't allow mRNA to produce more 7.

Answer:
Cilia, tail-like projections found on the surface of cells, are perhaps best known as molecular flippers that help cells move around. ... Cilia, tail-like projections found on the surface of cells, are perhaps best known as molecular flippers that help cells move around.
