Answer:
2. Circular, looped, folded, single stranded DNA known as the bacterial chromosome
Explanation:
The bacterial chromosome of a prokaryotic cell, does not occur in the typical X chromosome found in eukaryotic cells, but it is a long folded and looped molecule composed of double-stranded supercoiled DNA. In this case, DNA occurs freely and covalently closed in a circular shape in the cytoplasm and it does not bind with proteins.
Answer:
The cloned sheep is the result of nuclear fusion from two different sheeps. In one sheep the enucleated egg is fused with DNA of another sheep.
Explanation:
The cloned sheep is the result of nuclear fusion of 2 different sheep. In the cloning process, the egg cell of one sheep was enucleated. Then a DNA from another sheep had taken and put into the enucleated egg cell to fuse. Then the egg allowed to divide in the laboratory to the blastocyst stage. The blastocyst incorporated into a surrogate mother or a third sheep. The surrogate mother after some months gives birth to the cloned sheep.
The sheep produced by normal reproduction has the DNA of two parents. The sheep have two parents and resemble their parents.
In cloned sheep, there is no biological parent and have DNA of the donor sheep. That means the cloned sheep has a gene of a single sheep not the DNA of others. Because the egg cell was enucleated before the cloning process. The sheep are more like the donor DNA sheep not like the surrogate mother.
Answer:
B
Explanation:
In fact, mRNA's bases are directly copied from DNA. However mRNA's bases are complimentary to DNA's .!
