Would a bacterial cell undergo mitosis in the same way as a eukaryotic cell? Why or why not?
nikklg [1K]
Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm.

A single strand of DNA helix consists of 100 nitrogenous base pairs. On one strand, 36 of the bases are adenine and 24 are cytos
Katena32 [7]
Hello!

For the complementary strand of DNA, 36 Thymine bases and 24 Guanine bases would complete the proper base pairing. 

This is given by the concept of complementarity. A base in DNA has complementarity with only one other base. This complementarity is produced by hydrogen bond interactions.

For DNA, Adenine couples with Thymine and Cytosine couples with Guanine. So the 36 adenine bases will couple with 35 thymine bases, and so on. 

Have a nice day!

<span>D.Oxygen will diffuse from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell). This is because cells respire constantly, as this process uses up oxygen cells will contain less oxygen than its surroundings.
