Answer:
Non-coding DNA.
Explanation:
Inversion is a type of chromosomal abnormality in which the sequence of a segment of a chromosome is inverted or rotated at an angle of 180 degrees.  This type of abnormality can change the reading frame of the gene and can cause mutations.
But if the genome sequence is non-coding that is not involved in the formation of protein synthesis than even if the reading frame is inverted will not affect the phenotype of the cell. Also, the non-coding sequences are removed by the splicing mechanisms.
Thus, Non-coding DNA is correct.

A balance is best used to measure a sample's mass.
Answer: C
Explanation:
Weighing balance refers to a measuring instrument which is used to measure the mass of the sample. 
It has two pans. On one pan, the material to be weighed is placed, with adequate known loads on the other one to such an extent that the shaft will be in balance. 
The distinction between the zero perusing and the perusing with the dish stacked demonstrates the contrast between burdens in scale divisions. 
Such an instant weighing needs the arms be of equivalent length.
