Answer: The given statement is True.
Nuclear DNA is present in the nucleus of eukaryotic cells. When working with the DNA samples, the best source of nuclear DNA is hair root that anchors the whole shaft of hair. Hair root possesses cells that are called as keratinocytes. These cells are ideal for the extraction of nuclear DNA.
But, DNA is not always available in a hair sample as it can not be extracted from shaft of hair ( since it undergoes cornification that destroys the genetic material of the cells).
Thus, given statement is True.
Answer:
AUG (Methionine)
Explanation:
The process of protein synthesis occurs in two stages; transcription and translation. Transcription produces mRNA molecules from a DNA template. The mRNA's sequence is then read in a group of three nucleotides called CODON in the ribosome during the translation process.
Each Codon, of which there are possible 64, specifies an amino acid (building blocks of protein). Translation in the ribosome occurs when the ribosomal subunit binds to an mRNA molecule and a transfer RNA also binds using its anticodon (complementary to mRNA codon) to the AUG codon on the mRNA.
This AUG codon is regarded as the START CODON because it is the codon that initiates the commencement of translation. It encodes Methionine.

C. forests
D. industrial areas
Hedgerows have created new ecosystem within Britain's farms which are patchwork quilts.
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By the decomposition of the dead plants and animals by action of microbes nutrients are released back in to the soil.
