Why doesn't a bacteria have a nucleus in it?

Answer 1

The general efficiency of a cell is largely determined by its surface-to-volume ratio. Crudely, it gauges how much of the cellular volume is present compared to the surface area of the cell. As the cell gets larger, its volume measurement increases faster than its surface area measurement, making the ratio smaller. The larger the cell gets, the less efficient it becomes as its cellular material is far removed from each other. (Especially for Oocytes that are up to 100 microns in size)

Prokaryotes do not need nuclear membranes because they are comparably smaller than eukaryotic cells and thus their cellular material is close to each other for the efficient progression of biochemical processes. As such, they do not need a membrane. DNA-related processes are carried out in the nucleoid instead.

Answer 2

Bacteria are prokaryotes, which means they do not have a nucleus. Instead, their genetic material is found in the cytoplasm in a region called the nucleoid. This allows bacteria to have a simpler structure and enables them to replicate quickly.

Answer 3

Not having to ship the mRNA out of the nucleus. They transcribe their DNA directly to mRNA and right into the ribosome. They have long strings of transcription complexes hooked to many ribosomes in long rows. This makes for a quick transcription/translation process into protein product.

Answer 4

it's a prokaryote, and prokaryotes are extremely simple, single-celled life forms.

the reason human and plants have a nucleas is because we are eukaryotes, which can either be single-celled, or multi-celled, but have a nucleus.

Answer 5

because it's a porkaryote, which are single-celled simple life forms with out a nucleus.

humans and plants are known as eukaryotes, which can either be single-celled, like amoeba, or multi-celled, like a whale. thay have a nucleus.

Answer 6

the DNA is not bound in a nuclear membrane..

Answer 7

Bacteria are prokaryotic organisms. Prokaryotic by definition means no nucleus.

Answer 8

Bacteria is a type of prokaryotic cell that does indeed lack a cell nucleus. They also lack membrane enclosed organelles along with lacking a cell nucleus.

Answer 9

nucleus is not a 'bacteria'

bacteria don't hae nucleus.

nucleus is a cell organelle.

Answer 10

it all depends on what kind of bacteria it is. for example, Archaebacteria are prokaryotes, which means they do not have a nucleus.
