In detail what are the main differences in the 3 domains
DedPeter [7]

Answer:

Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell's ribosomal RNAs (rRNA), the cell's membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.

Comparing DNA Replication and Transcription

3' CTGGCTAC5'           5' GACCGATG 3'    3'CUGGCUAC 5'

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.
