2.

Which one given below is a DNA virus?

Poliovirus
Adenovirus
Reovirus
Hepatitis A virus

Correct Answer

A. Adenovirus

Explanation

Adenovirus is a DNA virus because it contains a double-stranded DNA genome. This type of virus replicates its genetic material using host cell machinery and can cause a variety of infections in humans, including respiratory and gastrointestinal illnesses. Poliovirus, Reovirus, and Hepatitis A virus are all RNA viruses, meaning they have a single-stranded RNA genome.

MC benign tumor of the lung is

Hamartoma
Alveolar adenoma
Teratoma
Fibroma

Correct Answer

A. Hamartoma

Explanation

A hamartoma is a benign tumor that consists of an overgrowth of normal cells and tissues that are normally found in the affected area. In the case of a benign tumor of the lung, a hamartoma would be the most likely explanation. It is important to note that a hamartoma is not cancerous and does not spread to other parts of the body.

Which of the following amino acids is purely ketogenic?

Phenylalanine
Leucine
Proline
Tyrosine

Correct Answer

A. Leucine

Explanation

Leucine is purely ketogenic because it can only be converted into ketone bodies and cannot be used for glucose synthesis. This means that leucine is solely metabolized to produce energy through the process of ketogenesis, making it a purely ketogenic amino acid. Phenylalanine and tyrosine are both considered to be both ketogenic and glucogenic, as they can be converted into both ketone bodies and glucose. Proline is primarily glucogenic, meaning it can be converted into glucose but not ketone bodies.

Which of the following does not cause an increase in serum amylase?

Pancreatitis
Ca lung
Renal failure
Cardiac failure

Correct Answer

A. Cardiac failure

Explanation

Cardiac failure does not cause an increase in serum amylase. Serum amylase levels are typically elevated in conditions such as pancreatitis, Ca lung (lung cancer), and renal failure. However, cardiac failure does not directly affect the pancreas or the production of amylase, so it does not cause an increase in serum amylase levels.

Most common medial meniscal tear is

Longitudinal tear
Oblique tear
Radial tear
Horizontal tear

Correct Answer

A. Longitudinal tear

Explanation

A longitudinal tear is the most common type of medial meniscal tear. This type of tear occurs along the length of the meniscus, usually in a vertical direction. It is commonly caused by degeneration or wear and tear of the meniscus over time. Longitudinal tears can cause pain, swelling, and limited range of motion in the knee joint. Treatment for this type of tear may include rest, physical therapy, and in some cases, surgery to repair or remove the damaged portion of the meniscus.

A major lipid of mitochondrial membrane is

Lecithin
Inositol
Plasmalogen
Cardiolipin

Correct Answer

A. Cardiolipin

Explanation

Cardiolipin is a major lipid of the mitochondrial membrane. It is a unique phospholipid that is found exclusively in the inner mitochondrial membrane. It plays a crucial role in maintaining the structural integrity and function of mitochondria. Cardiolipin is involved in various mitochondrial processes, including electron transport chain activity, ATP synthesis, and apoptosis regulation. It also interacts with numerous mitochondrial proteins, contributing to their proper localization and function. Therefore, cardiolipin is an essential component of the mitochondrial membrane and is critical for the proper functioning of mitochondria.

Von Brunn's nest is seen in

Normal urothelium
Transitional cell carcinoma
Squamous cell carcinoma
Adenocarcinoma

Correct Answer

A. Normal urothelium

Explanation

von Brunn's nests are benign proliferations of urothelial cells that form small, rounded, and often cystic structures within the urothelium. They are commonly found in normal urothelium and are not associated with any pathological condition. Therefore, the correct answer is normal urothelium.

Acute and recurrent pancreatitis is reported to occur in

Homocystinuria
Maple syrup urine disorder
Methylmalonic acidemia
Tyrosinemia

Correct Answer

A. Methylmalonic acidemia

Explanation

Methylmalonic acidemia is a metabolic disorder that leads to the accumulation of methylmalonic acid in the body. This can result in damage to various organs, including the pancreas. As a result, individuals with methylmalonic acidemia are at an increased risk of developing acute and recurrent pancreatitis. This explains why acute and recurrent pancreatitis is reported to occur in individuals with methylmalonic acidemia.
