Answer:
False
Explanation:
Introns need to be removed precisely because the reading frame will be shifted if removed even single nucleotide too many or leaving an intronic nucleotide in the spliced mRNA .
Extra amino acids will be inserted if large pieces of introns are left in the mature messenger RNA.
In both cases, aberrant protien will be produced if the RNA splicing is not precise, hence they are needed to be removed by precision.

Answer:
C6H6 - organic compound
K - element
Cl2 - inorganic elemental molecule
SO2 - inorganic compound
Explanation:
An organic compound contains carbon and hydrogen bonded covalently . Sometimes other atoms aside from carbon and hydrogen called heteroatoms are also found in organic compounds. C6H6 is an organic compound.
Elements are found in periodic table. They always occur in uncombined state. K is an element.
Cl2 is an inorganic elemental molecule containing two chlorine atoms bonded covalently.
SO2 is an inorganic compound composed of sulphur and oxygen bound covalently. Mnay inorganic compounds do not contain carbon

Answer: Option D " all of the above "
Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.
Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.
Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.
Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.
Hence, the correct answers are all of the above.
