Question

1. place the four steps of binary fission in order from start to finish.

a – the cell splits into two cells
c – copy of chromosome is produced
b – the cell enlarges & chromosomes separate
d – chromosomes connect to the cell membrane

1. which special structure is used to transfer dna from one bacterium to another?

1. which process is described in the previous question?

1. which medicines are prescribed to treat bacterial infections and why it’s important to finish them?

Explanation:

Question 13

Step1: Recall binary fission steps

Binary fission starts with DNA replication (copy of chromosome, C). Then chromosomes connect to cell membrane (D). Next, cell enlarges and chromosomes separate (B). Finally, cell splits into two (A).

Step2: Order the steps

Start with C, then D, then B, then A.

Bacteria use pili (specifically sex pili) to transfer DNA during conjugation.

The process where DNA is transferred between bacteria via pili is bacterial conjugation.

Answer:

C, D, B, A
