DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In eukaryotes, DNA:
A
floats freely in the cytoplasm
B
is found in the nucleus
C
is wrapped within the ribosome
D
is circular
Explanation: 

Detailed explanation-1: -In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.

Detailed explanation-2: -The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA.

Detailed explanation-3: -Eukaryotic cells contain membrane-bound organelles (such as the nucleus and mitochondria), while prokaryotic cells do not. DNA in eukaryotic cells is found inside the nucleus, while DNA in prokaryotic cells is located in the cytoplasm.

Detailed explanation-4: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Detailed explanation-5: -In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein.
