Molecular clocks B. TAKE ADVANTAGE OF THE FACT THAT ALL MUTATIONS HAPPEN AT A STEADY RATE.
The molecular clock is a technique used involving the mutation rate of biomolecules to deduce when in prehistoric times have two or more lifeforms diverged.
Answer:
Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. Metal is a good conductor of heat, hence it sends away the heat. On the other hand, wood is a poor conductor of heat, hence releases the heat too slowly.
Answer:
Explanation:
Enzyme are protein molecules that catalyzes chemical reaction.
In DNA replication, enzymes play a major role.
Enzymes identify the starting point of replication, attach itself and then unwind the Deoxyribonucleotide acid DNA Strand to form the replication fork.
Enzyme Helicase unwind and breaks the hydrogen bond between the base pair, opening up the helix structure to form a template for the new strand.
DNA polymerase also play a major role, it synthesis new DNA by adding primer to the DNA sequence for replication to occur, they also proof read the copy of DNA Strand being made to avoid errors during replication and add nucleotide to the growing DNA strand.
It is made of two Hydrogen atoms and one Oxygen atom. That is why it is called H2O
