main enzyme involved in DNA replication

• semi-conservative

• DNA replication

• DNA polymerase

• ribonucleic acid

a term used to describe the copying of DNA, since half of the original DNA is used as a new template to create the new DNA strand

• semi-conservative

• DNA replication

• DNA polymerase

• ribonucleic acid

single-stranded nucleic acid that contains the sugar ribose

• semi-conservative

• DNA replication

• DNA polymerase

• ribonucleic acid

Why is DNA replication described as semi-conservative?

• The original DNA is read by an enzyme to create an entirely new copy

• DNA is really easy to copy, so it conserves the cell's energy

• 1/2 of the original DNA is conserved and used to create 1/2 of a new strand

• The original DNA is not conserved in the process and therefore destroyed after replication

True or false: RNA contains the same bases as DNA

• True: Both RNA and DNA contain adenine, thymine, guanine, and cytosine.

• False: RNA does not contain thymine. It is replaced by the base uracil.
