Sample Question
What is slipped strand DNA mismatch?

Is a mutation process which occurs during DNA replication. It involves denaturation and displacement of the DNA strands, resulting in mispairing of the complementary bases. Slipped strand mispairing is one explanation for the origin and evolution of repetitive DNA sequences.[1] Slipped strand mispairing has also been shown to function as a phase variation mechanism in certain bacteria.SSM events can result in either insertions or deletions. Insertions are thought to be self-accelerating: as repeats grow longer, the probability of subsequent mispairing events increases. Insertions can expand simple tandem repeats by one or more units. In long repeats, expansions may involve two or more units. For example, insertion of a single repeat unit in GAGAGA expands the sequence to GAGAGAGA, while insertion of two repeat units in [GA]6 would produce [GA]8. Genomic regions with a high proportion of repeated DNA sequences (tandem repeats, microsatellites) are prone to strand slippage during DNA replication.

A type of mutation that is beneficial for DNA replication.

A process that occurs during protein synthesis.

A mechanism that prevents mutations during DNA replication.

Sample Question
In a double helix structure, which parts of a twisted ladder are analogous to the hydrogen bonds and the sugar-phosphate backbones of DNA?

The sugar-phosphate backbone represent the rungs of the ladder. Hydrogen bonds represent the two long sides of the ladder.

The sugar-phosphate backbone do not play a role in the twisted ladder analogy. They represent a different structural element.

Hydrogen bonds represent the rungs of the ladder. The sugar-phosphate backbone represent the two long sides of the ladder.

Hydrogen bonds represent the two long sides of the ladder. The sugar-phosphate backbone represent the rungs of the ladder.
