Question

differentiate between nucleoid and nucleus. what are their functions ?​

Answer 1

Answer:

The key difference between nucleus and nucleoid is that nucleus is a membrane-bound organelle in the eukaryotes' cytoplasm and nucleoid is a particular area in the prokaryotes' cytoplasm.

hope this helps you..

Answer 2

Answer:

Explanation:

NUCLEOID

- NUCLEOID IS A PARTICULAR AREA IN WHICH PROKARYOTES STORE THEIR GENETIC MATERIALS.

- NUCLEOID IS POORLY ORGANISED AND IS SMALL.

- NUCLEOID LACKS A PROTECTIVE MEMBRANE.

- NUCLEOID IS AN IRREGULARLY SHAPED MEMBRANE.

FUNCTIONS OF NUCLEOID

- Nucleoid is the part of cell which contains primary DNA material.

- It includes enzymes & proteins that transcribe RNA & DNA.

- Some enzymes & proteins included in it act as biological catalysts

- Nucleoids also assist in cell development & growth.

NUCLEUS

-  A NUCLEUS IS A MEMBRANE BOUND STRUCTURE IN WHICH EUKARYOTES STORE THEIR GENETIC MATERIALS.

- A NUCLEUS IS WELL ORGANIZED AND IS LARGE.

- NUCLEUS IS SURROUNDED BY A DOUBLE MEMBRANE.

- A NUCLEUS IS A SPHERICALLY SHAPED ORGANELLE.

FUNCTIONS OF NUCLEUS

- It controls the heredity characteristics of an organism.

- It is responsible for protein synthesis, cell division, growth and differentiation.

- Stores heredity material in the form of deoxy-ribonucleic acid (DNA) strands.Also stores proteins and ribonucleic acid (RNA) in the nucleolus.
