How does the structure of the muscle cell help it carry out its function? <br>plz answer​
Korvikt [17]

Answer:

Different types of cells shapes effect the function of the cells. Muscle cells are shaped like they are because they have to perform a certain function to meet the critia of what the body is telling it what to do.

Explanation:

Skeletal muscle cells are located in a bundle of linear fibers. These are thin chains of the proteins actin and myosin that cause muscle contraction. The elongated shape of muscle cells allows contractile proteins to place themselves in an overlapping pattern that allows muscle flexion.

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