A biochemist isolates and purifies various molecules needed for DNA replication. When she adds these molecules to DNA, replicati

on occurs, but half of the DNA produced consists of a normal DNA strand paired with numerous segments of DNA a few hundred nucleotides long. What has she probably left out of the mixture

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.

Why are plants crunchy when your eat them, but animal protein (meat) is not?
irina1246 [14]

Answer:

The correct answer is - cell wall made up of cellulose that makes it crunchy.

Explanation:

In plant-based foods, the outer membrane is a cell wall that provides structure and supports the plant to stand erect and protect from the outer environment. The cell wall is mainly composed of cellulose that is a carbohydrate which is comparatively crunchy or tough to the animal protein with a fatty cell membrane that makes it chewier than the crunchy.

The composition of the protective layers of the plant cels and animal cell causes this difference in their texture.
