Answer 1

The correct completion for the enzyme that 'reassembles the newly copied DNA molecules' and 'reads' the original DNA strand is 'b. Catalyzes.' DNA polymerase is the enzyme responsible for synthesizing the new DNA strands during replication, recognizing template strands and matching nucleotides to form new complementary strands.

Step-by-step explanation:

The enzyme reads the original DNA strand by unwinding the DNA helix and recruiting the appropriate enzymes for DNA replication. DNA polymerase is the enzyme that catalyzes the formation of ester bonds during DNA replication, making the statement 'The enzyme reassembles the newly copied DNA molecules.' correctly completed with 'b. Catalyzes.' DNA polymerase recognizes each base in a template strand and matches it to the complementary base in a free nucleotide, which is then added to the growing DNA chain. The term 'The enzyme 'reads' the original DNA strand.' would also be completed with 'b. Catalyzes,' implying that enzymes are responsible for catalyzing the reactions involved in the process of replication.

Moreover, the enzyme that uses RNA as a template to produce a DNA copy is DNA polymerase, which validates the accurate process of replicating the parent DNA to form two semi-conserved DNA molecules, each containing an original strand from the parent molecule and a newly synthesized one. This replication process is part of the cell division cycle, ensuring that each new cell has the necessary genetic information to function properly.
