What do you think would happen if a cell's DNA did not replicate correctly?

Answer 1

If the DNA did not replicate, daughter cells would not be formed. The reason for this can be explained by the cell cycle which has four phases: G1, S, G2 and M. The S phase is the synthesis phase where DNA is replicated, in addition to many other cellular events. If the DNA fails to replicate, the cell will not go into G2 and M(mitosis) phases. A cell that halts at the G2/M checkpoint due to replication errors will kill itself through a process called apoptosis

Answer 2

DNA information is read using base pairs of nucleotides. The cell reads genes in groups of three bases. Each group of three bases (codons) corresponds to one of 20 different amino acids used to build a protein.

If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.
Here is an example of one sentence with words of only three letters: The big red pig ate the red rag. Each word will make one amino acid and the words make a sentence that makes sense.

Mutations that replaces one base for another will result in this: The beg red peg ate the red rag. This mutation can be read OK.

But another type might make the sentence totally readable: The big res dpi gat eth ere dra g.

Answer 3

If a cell's DNA did not replicate correctly, it could lead to mutations in the genetic material. The mutations may affect gene expression, protein production, and cell function, potentially leading to errors in cell division, cell death, or diseases like cancer.

Answer 4

If the DNA did not replicate, daughter cells would not be formed.

Answer 5

It depends on how much and on what chromosome the duplication occurred. Some can cause the protein that was to be made to be nonfunctioning and unusable.
