Explanation / Answer

1. The difference between a prokaryotes and eukaryotes are as follows:

2. Mitochondria produces energy for the cells called ATP and has its own DNA. It is also called as powerhouse of the cells.

3. The two members of homologous chromosomes have the same genes, genes order and approximate length in common.

4. In DNA, the complementary base pairing for adenine is thymine as both are bound with double bond and guanine binds with cytosine having triple bonds.

In RNA, the cimplemcomple base pairing for adenine is uracil as both are bound with double bond and guanine binds with cytosine having triple bonds.

PROKARYOTES EUKARYOTES Size of cell is 1-2µm. Size of cell is greater than 5 µm in diameter. unicellular cell type. multicellular cell type. Nucleus lack nuclear membrane and nucleolus. Such nucleus is called nucleoid. Nuclear membrane and nucleolus are present. Usually single circular without histones chromosome is present. Multiple linear with histones chromosome is present. Binary fission of budding cell division occurs. Involves mitosis for cell division. Membrane- bound organelles are absent. MMembrane- bound organelles are present. Extra chromosomal plasmid is present. Extra chromosomal plasmid is absent. Transcription and translation occurs simultaneously. Transcription and translation occur in nucleus and cytoplasm respectively.
