Answer:

Option). duplication.

Explanation:

Mutations are permanent changes in DNA, due to change in its nucleotide sequence. A mutation that occurs due to replication or duplication of a portion of genetic material is known as duplication.  

As altered sequence in given bacterium represents duplication of three guanine nucleotides, the type of mutation that caused this sequence change is duplication.

Original sequence: act<u>ggg</u>atcct

Altered sequence:  atcggggggatcct

Thus, the correct answer is 'duplication.'

Anastasy [175]

The question is incomplete. The complete question is:

Question: What is the expected percent change in the DNA content of a typical eukaryotic cell as it progresses through the cell cycle from the start of the G1 phase to the end of the G2 phase

a. -100%

b. -50%

c. +50%

d. +100%

Answer:

d. +100%

Explanation:

S phase comes between G1 and G2 phases of the interphase of a cell cycle. S phase of interphase includes replication of DNA. The process of DNA replication doubles the amount of DNA present in the cell. The newly synthesized DNA is accommodated in the sister chromatids of chromosomes. Therefore, a cell with 2C DNA in the G1 phase would have 4C DNA at the end of the G2 phase. So, there is a +100% increase in the DNA content of a cell as it proceeds from G1 to the end of the G2 phase.
