5. Which among the following is essential gene material ?
[A] Protein
[B] Fat
[C] DNA
[D] RNA
Show Answer
Correct Answer: C [DNA]
Notes:
The correct answer is DNA. DNA (deoxyribonucleic acid) is the essential genetic material in most living organisms, encoding the instructions for development, functioning, growth, and reproduction. It is composed of nucleotides and forms a double helix structure. RNA (ribonucleic acid) plays a crucial role in protein synthesis and can also serve as genetic material in some viruses, but DNA is the primary carrier of genetic information in cells.

8. What is that gene called which have two or more than two characters?
[A] Duplicate gene
[B] Pleiotropic gene
[C] Polymeric gene
[D] Su-HW gene
Show Answer
Correct Answer: B [Pleiotropic gene]
Notes:
A single gene may have two or more phenotypic expressions or characters. The multiple phenotypic effect of a single gene is called pleiotropism. Hence the gene associated with this phenomenon is called Pleiotropic gene.

Show Answer
Correct Answer: B [The line of descendants of a particular ancestor]
Notes:
A lineage is a single line of descent or linear chain within the tree while a clade is a monophyletic group, containing a single ancestor and all its descendants. Phylogenetic trees are typically created from DNA, RNA or protein sequence data.
