Answer:

DNA ligase

Explanation:

DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;

  • initiation
  • elongation
  • termination

<em>Initiation </em>involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme

<em>Elongation</em> involves binding of RNA primer to the DNA strands and addition of bases to the primer<em> </em>to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).

<em>Termination</em> involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.

<em>The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.</em>

Hence, the answer is DNA ligase.

Drag each label to the correct location.
Marizza181 [45]

Answer:

* Glucose may cause an increase in bacterial growth - HYPOTHESIS

* The bacterial colonies grown without glucose don’t have capsules around their cells - OBSERVATION

* Bacterial growth in the glucose environment increased rapidly and then stopped after some time - OBSERVATION

* Increased glucose may lead to capsule formation in bacteria - HYPOTHESIS

Explanation:

In an experiment, a HYPOTHESIS is a predictive and testable statement that aims to answer a scientific question while an observation is made based on the results obtained.

According to this question, Annie wants to study the effect of glucose on bacterial colonies. She conducted the experiment by growing two colonies of bacteria - one with glucose present in the environment and one in an environment without glucose. Based on this experiment, the following statements are categorized as:

- Glucose may cause an increase in bacterial growth is a HYPOTHESIS

- The bacterial colonies grown without glucose don’t have capsules around their cells is an OBSERVATION

- Bacterial growth in the glucose environment increased rapidly and then stopped after some time is an OBSERVATION

- Increased glucose may lead to capsule formation in bacteria is a HYPOTHESIS
