An enzyme in a cell became dysfunctional because of an alteration. as a result, the dna strands would not separate to begin the replication process. which enzyme has been affected?me a. dna ligase b. dna polymerase c. helicase d. rna primase e. topoisomerase

Answer;

-Helicase enzyme

Explanation;

-Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid protein complexes. DNA helicases are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied.

-DNA is double stranded. Enzymes that are responsible for replication of DNA can only bind to a single strand of DNA. Helicase is the enzyme that unwinds the DNA by breaking hydrogen bonds between the two strands.It forms the so called replication fork. Other proteins assist helicase to keep the strands apart as long as required for the replication process.

helicase is the answer

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
