A biochemist isolates and purifies various molecules needed for DNA replication. When she adds some DNA, replication occurs, but each DNA molecule consists of a normal strand paired with numerous segments of DNA a few hundred nucleotides long. What has she probably left out of the mixture? A biochemist isolates and purifies various molecules needed for DNA replication.

DNA ligase

Explanation: During replication, two new strands are synthesized: The leading strand and the lagging strand.

The leading strand is synthesized in a continuous manner while the lagging strand is synthesized discontinuously in short segments called the Okazaki fragments. The leading strand is the strand whose 5'->3' synthesis is in the direction of the fork movement while the lagging strand is the strand whose 5'->3' synthesis is in the direction opposite to the fork movement. The Okazaki fragments are joined by an enzyme known as DNA ligase. DNA ligase is one of the enzymes involved in DNA replication which catalyzes the joining of two or more polynucleotide chains.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
