Without external forces the third generation of bacterium and the original parent cell will have approximately
A. 100% dna
B. 12.5 dna
C. 25% dna
D. 33% dna
C. 25% dna
To determine the amount of DNA in the third generation of bacteria and the original parent cell without external forces, we need to consider the process of DNA replication.
In each generation of bacterial replication, the DNA is copied, and each offspring cell receives a full copy of the DNA from the parent cell. This means that the amount of DNA remains constant from generation to generation.
Therefore, the third generation of bacteria and the original parent cell will both have 100% of the DNA.
So, the correct answer is A. 100% DNA.
To determine the amount of DNA in the third generation of bacterium and the original parent cell, we need to consider how DNA is passed on during cell division. In most cases, genetic material is copied and divided equally between daughter cells during cell replication.
In the case of bacteria, they reproduce asexually through a process called binary fission. During binary fission, the parent bacterium divides into two identical daughter cells. Each daughter cell receives an exact copy of the parental DNA.
Based on this understanding, we can conclude that the third generation of bacterium and the original parent cell will have 100% DNA. This means that option A, "100% DNA," is the correct answer.
