difference between prokaryote and eukaryote
Answers
Answer:
- eukaryotic cells have a membrane-bound nucleus
- prokaryotic cells do notThe nucleus is only one of many membrane-bound organelles in eukaryotes.
- eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not
- Prokaryotes, on the other hand, have no membrane-bound organelles.
Answer:
Prokaryotic DNA vs Eukaryotic DNA
Prokaryotic DNA Eukaryotic DNA
Location
Found freely in the central portion of the cytoplasm. Found within the nucleus.
Occurrence
Occurs as a covalent closed circular form of DNA. Occurs as a linear form of DNA with two ends.
Size
The size of the DNA is less than 0.1 pg in prokaryote. The size of the DNA is high, usually more than 1 pg.
Introns
Introns are absent in the coding region of DNA. Introns are present in the coding region of DNA.
Nucleosome
There is no formation of nucleosome. There is a formation of nucleosome.
Quantity of the DNA
The quantity of the DNA is comparatively less. The quantity of the DNA is more.
Chromosome
Do not form chromosomes. Forms chromosomes in the nucleus.
DNA Replication
DNA replication occurs in the cytoplasm of the cell. DNA replication occurs within the nucleus of the cell.
Number of Genes
Prokaryotic DNA contains a small number of gene. Eukaryotic DNA contains a large number of genes.
Transposons
Prokaryotic DNA lacks transposons. Eukaryotic DNA consists of transposons.
Number of Chromosomes
Prokaryotic DNA is organized into a single chromosome. Eukaryotic DNA is organized into many chromosomes.
Histone Proteins
Do not interact with the histone proteins. Associated with the histone proteins.
