Livofy Interview Questions and Answers

The portion of the sp**m cell that contains the twenty-three chromosomes is the head.

• The head of the sp**m cell contains the genetic material, including the twenty-three chromosomes.

• The tail of the sp**m cell is responsible for movement and does not contain genetic material.

• The head of the sp**m cell is where the genetic material is packaged and protected.

• Examples of structures in the head of the sp**m cell include the nucleus and acrosome.

Nucleolus is the site of ribosomal RNA synthesis.

• The nucleolus is a specialized structure within the nucleus of a cell where ribosomal RNA (rRNA) is synthesized.

• rRNA is a key component of ribosomes, which are responsible for protein synthesis in cells.

• The nucleolus also plays a role in ribosome assembly.

• Examples of cells with prominent nucleoli include rapidly dividing cells like cancer cells.

A hapten is a small molecule that can elicit an immune response only when attached to a larger carrier molecule.

• Haptens are not immunogenic on their own but can become immunogenic when bound to a carrier protein.

• Examples of haptens include penicillin and dinitrophenol.

• Haptens are important in the field of immunology and vaccine development.

The most accurate and safest technique to diagnose cancer is biopsy.

• Biopsy involves taking a sample of tissue from the suspected area and examining it under a microscope to look for cancer cells.

• There are different types of biopsies such as needle biopsy, surgical biopsy, and endoscopic biopsy.

• Biopsy is considered the gold standard for diagnosing cancer as it provides a definitive answer.

• Other diagnostic techniques like imaging tests (CT scan, MRI, PET scan) can help in detec...read more

CRISPR-Cas system is a bacterial defence mechanism against bacteriophage.

• CRISPR-Cas system helps bacteria defend against bacteriophage by targeting and destroying their DNA.

• It works by storing snippets of phage DNA in the bacterial genome and using them to recognize and attack the phage upon reinfection.

• CRISPR-Cas system has been used in genetic engineering and gene editing technologies.

• Examples of bacteria using CRISPR-Cas system include Streptococcus pyogenes and Escherichi...read more
