Answers

RNA nucleotides form complimentary base pairs with DNA bases. Hydrogen and sugar-phosphate bonds form and the mRNA is synthesized.

Explanation:

The process of mRNA formed by DNA is called transcription. The genes coding for the protein is present on DNA as a nitrogenous base or nucleotides.

Transcription takes place inside the nucleus with the assistance of major enzyme RNA polymerase. In transcription 5'to3' single strand of RNA is synthesized which is complementary to the 3'to5' strand of DNA. The sequence of DNA has promoter sites which will be recognized and DNA will unzip to form transcription bubble. Several transcription factors and enzyme will be required to synthesize mRNA.

This mRNA after some modification would become primary transcript and pass on to the cytoplasm where protein synthesis will take place.

Final answer:

Diamond and corundum are materials that have a higher hardness rating than Quartz and can scratch it.

Explanation:

According to the Mohs Scale of Hardness, the materials that would be able to scratch Quartz are those with a higher hardness rating. In this case, both diamond (hardness 10) and corundum (hardness 9) would be able to scratch Quartz (hardness 7).
