Message 2. It can be used to delete, insert, or modifygenes within organismsAssignmentQ.1) With reference to CRISPR-Cas9 technology,consider the following statements:1. It is a gene-editing tool derived from bacterialimmune systems.3. It requires the use of viral vectors for editinggenes.How many of the statements given above arecorrect?[a] Only 1[b] Only 2[c] All of the above[d] None

Correct Answer: [b] Only 2Explanation-CRISPR-Cas9 originates from bacterialimmune systems, where it helps bacteriarecognize and cut viral DNA to preventinfections. vCRISPR-Cas9 can be programmed to delete,insert, or modify specific genes within thegenome of organisms. vCRISPR-Cas9 does not require viral vectorsfor gene editing. It primarily uses guide RNAto locate the DNA sequence and the Cas9protein to cut it.

Key Features:Specificity:CRISPR-Cas9 can be programmed to targetvirtually any DNA sequence by designingthe appropriate guide RNA. Simplicity:Compared to previous gene-editingmethods, CRISPR-Cas9 is relatively easier todesign and implement, making it a moreaccessible tool for researchers.

Versatility:It can be used to disrupt, modify, orinsert genes, and even regulate geneexpression. Accuracy:While generally accurate, off-targeteffects (editing at unintended locations)can occur and are a focus of ongoingresearch.

Q.2) Which of the following rivers originatesfrom the Amarkantak Plateau?1. Narmada2. Godavari 3. Mahanadi Correct Answer: [a] Narmada 4. Tapti

Narmada River, originates from theAmarkantak Plateau in Madhya Pradesh. Itflows westward between the Vindhya andSatpura ranges. The Godavari, also called the DakshinGanga, originates from the Trimbak Hills inthe Western Ghats, Maharashtra. Mahanadi, originates from the Sihawa hillsin Chhattisgarh, not Amarkantak.Tapti, originates from the Satpura Range.Explanation-

Facts;Amarkantak is primarily known as asignificant Hindu pilgrimage center and aplace of natural beauty, earning it the title"Teerthraj" or "King of Pilgrimages".The Narmada River rises from theAmarkantak Plateau in Anuppur district inMadhya Pradesh.Ancient name of Amarkantak was Rikshaparvat.

Q.3) With reference to Indian classical danceforms, consider the following statements: 1. Bharatanatyam is known for its fixedupper torso and bent legs. 2. Kathak is characterized by intricatefootwork and spins. 3. Odissi is associated with the temples ofTamil Nadu. How many of the statements given aboveare correct? [a] Only 1 [b] Only 2 [c] All of the above[d] NoneCorrect Answer: [b] Only 2

Bharatanatyam, originating from TamilNadu, is characterized by a fixed upperbody, bent legs, and intricate gestures andexpressions. Kathak, a classical dance form from NorthIndia, is known for its fast footwork(tatkaar), spins (chakkars), and storytellingthrough gestures. Odissi originates from Odisha, not TamilNadu, and is known for its tribhangi postureand temple sculptures, particularly in theJagannath Temple. Explanation-

Facts:It originated in Uttar Pradesh, India,and is one of the six major Indianclassical dance styles.The name "Kathak" is derived from theSanskrit word "katha," meaning story,reflecting its roots in the storytellingtraditions of ancient India.
