olga55 [171]

Answer:

DNA ligase

Explanation:

<em>The biochemist must have left out DNA ligase enzyme.</em>

<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>

The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.

Hence, the missing component is the DNA ligase.

The major function of the mitochondria is to perform cellular respiration and produce energy in the form of ATP by oxidating organic molecules. All the process requires energy to be processed, however, the main and primary process that would disturb if by the destruction of the mitochondria occur which is the oxidation of glucose to convert it to pyruvic acid to generate energy.

The Krebs cycle that takes place in mitochondria and performs oxidation of organic molecules will also be disturbed and there will be no energy for any process.
