Answer:

In relative dating, fossils are dated according to the depth at which they were buried While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils.

Comparing DNA Replication and Transcription

The missing information has been completed as:

DNA Tempelate        complementary DNA    mRNA

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.
