What does before nucleus mean?
"Before nucleus" typically refers to the time period in a cell's history when it did not have a defined nucleus. This is known as the prokaryotic phase, where genetic material is not enclosed by a membrane-bound nucleus, as seen in organisms like bacteria.
The term prokaryotic means what-literally?
The term "prokaryotic" literally means "before the nucleus." It is derived from the Greek words "pro," meaning "before," and "karyon," meaning "nut or nucleus." Prokaryotic organisms, such as bacteria, lack a membrane-bound nucleus and other membrane-bound organelles, distinguishing them from eukaryotic cells, which have a defined nucleus.
What is the difference between parent nucleus and daughter nucleus?
The parent nucleus is the original nucleus before undergoing radioactive decay, which results in the formation of a daughter nucleus. The daughter nucleus is the nucleus that is produced as a result of the radioactive decay of the parent nucleus.
In which organelle is DNA kept and RNA transcript?
DNA is kept in the nucleus, while RNA transcription occurs in the nucleus before the mRNA moves to the ribosomes in the cytoplasm for translation.

What is the meaning of the word parts pro and karyo?
"Pro" means before or in favor of, while "karyo" refers to nucleus. So, "prokaryo" could be interpreted as "before nucleus" or "lacking a true nucleus," as seen in prokaryotic cells that do not have a membrane-bound nucleus.

What organisms have cells with no nucleus?
Prokaryotes. That's why they're called prokaryotes- pro-before, karyon-nucleus.
What is the main difference between eukaryotic and prokaryotic cells?
Prokaryotic cells contain no nucleus... where as eukaryotic are nucleus containing cells... I rememeber it by saying PRO- means before... its BEFORE they have a nucleus
What is a term that represents the number of chromosomes in th nucleus before mitosis?
The number of chromosomes in the nucleus before mitosis is dependent on the species. The exact number is called the ploidy of the animal.

What is the Headquarters of cell operations?
The headquarters of cell operations is the nucleus, where DNA is stored and controls the cell's activities. This is where genetic information is transcribed into messenger RNA before being translated into proteins in the cytoplasm.
