<u>Sediment</u> is formed as a result of interaction of igneous rock with wind and water over a long period of time.
<u>Explanation</u>:
An igneous rock is formed by the weathering of the molten earth material. If the igneous rock is continuously exposed to wind and water for long time then the fragments of the rock will get loosened. This causes the fragment to fall off and sediments will be formed.
Sediment is a material that is broken off from the rocks due to specific weather condition. As metamorphic rock requires high temperature or high pressure for its formation, it cannot occur with the interaction of wind and water.
The given question is incomplete, the complete question is:
A particular type of DNA damage involves purely chemical (non-enzymatic) degradation steps, like deamination, or depurination. Due to these, and other forms of DNA damage, cells employ a range of DNA repair mechanisms in order to maintain the integrity of the genetic code over millions of generations. Many eukaryotic cells have a specialized repair mechanism for the repair of G-T mismatches. This mismatch is repaired to form G=C (not A=T) base pair. This G-T mismatch repair mechanism occurs in addition to a more general system that repairs virtually all mismatches. Suggest a reason why cells might require a specialized system to repair G-T mismatches in this way.
Answer:
The repair of G-T mismatch is performed through the process called very short patch repair. The mismatch takes place because of the deamination of 5-methyl cytosine into thymine that occurs due to DNA mutation. The process of repair is performed with VSR endonuclease that eradicates the thymine on 5 prime end and then resynthesis of the patch is done with the assistance of DNA polymerase.
In case, if the repair does not take place it can result in transition mutation, that is, a kind of point mutation. As this repair is required to be very accurate, thus, the special VSR endonuclease is used for very short patch repair.
