Which best describes a transgenic organism ?

biology genetics of the future genetically modified animals and crops transgenic organisms biotechnology and its applications

  1. One that act as the donor for DNA to be moved into another organism

  2. One produced by cloning a mutant cell

  3. One that contains a foreign gene and is free- living in the environment

  4. Any genetically modified organism- resulting from laboratory research

Show answer
Correct Option: C
Explanation:

Transgenic Organism or Genetically Modified Organisms (GMO) is an organism whose genetic material has been altered using genetic engineering techniques. Bacteria are the easiest organism to engineer and have been used for research, food production, industrial protein purification etc. There is a potential to use them for environmental purposes or as medicines.

So, the correct option is 'One that contains a foreign gene and is free-living in the environment'.

Genes found in plants and animals that are of actual or potential value to people are known as

biology genetics of the future genetically modified animals and crops transgenic organisms biotechnology and its applications

  1. genetic resources

  2. biotic resources

  3. oceanic resources

  4. natural resources

Show answer
Correct Option: A
Explanation:

There are various genes that are found in animals and pants that are of important use for the humans. These genes are extracted and then introduced into organisms by genetic engineering.

These genes are known as genetic resources.
So, the correct option is 'genetic resources'

Select the correct statement with respect to locomotion in human:

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. The joint between adjacent vertebrae is a fibrous joint

  2. A decreased level of progesterone cause osteoporosis in old people

  3. Accumalation of uric acid crystals in joints cause their inflammation

  4. The vertebral column has $10$ thoracic vertebrae

Show answer
Correct Option: C
Explanation:

Locomotion is the process of movement of an organism from one place to another.

  • The fibrous joint is a fixed joint and is present in the bones of the skull while the synovial joint is present in the bones of the vertebrae making it movable.
  • Progestrone is a hormone responsible for the menstruation cycle and pregnancy.
  • The process of accumulation of the uric acid in the form of crystals at the place of joints causes inflammation and joint pain, this condition is termed as gout.
  • The vertebral column has 33 vertebrae out of which 27 presacral vertebrae, 7 cervical, 12 thorasic, and 5 lumbar vertebrae are found.

So, the correct option is 'Accumulation of uric acid crystals in joints cause their inflammation'

How many statements are correct regarding Rheumatoid arthritis?


(a) Caused due to activation of Rheumatic factor IgG type antibody
(b) Synovial joints are affected
(c) Pannus particles are formed by articular cartilage
(d) Rheumatic factor is activated by recurrent E.coli infection
(e) Articular cartilage is damaged by pannus particles.

  1. One

  2. Two

  3. Three

  4. Four

Show answer
Correct Option: C
Explanation:

Answer is C. Three

A In rheumatoid arthritis an antibody against the Fc portion of IgG and different RFs can recognize different parts of the IgG-Fc. RF and IgG join to form immune complexes that contribute to the disease process.
B. The synovial membrane produces synovial fluid – a clear fluid that lubricates and nourishes the joint. Rheumatoid arthritis can affect any joint in the body but usually affects the small joints in the hands and feet before any of the larger joints such as hips, knees, shoulders and elbows are affected.
E.pannus — an abnormal tissue growth in the joints. This tissue can spread to your bones and cartilage, causing cartilage destruction, bone deterioration, pain, and inflammation.

Which of the following statements are true regarding gout disease?

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1.  Gout occurs when urate crystals accumulate in joint.

  2. Drinking alcohol of any type can trigger a gout attack

  3.  Uric acid can build up, forming sharp, needle like urate crystals in a joint or surrounding tissue that cause pain

  4. All of the above

Show answer
Correct Option: D
Explanation:

Gout is a type of arthritis, the disease caused by the disorder of uric acid metabolism in which uric acid crystals are accumulated in joints, tendons and surrounding tissues which leads to inflammation and pain.
Symptoms of gout include severe pain, redness and swelling in joints, often the big toe.
Drinking alcohol of any type can trigger a gout attack because drinking alcohol leads to accumulation of uric acid crystals in the body.
So, the correct option is 'All the above'

Secretion of abnormal pannus is seen in which of the following abnormalities?

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Rheumatoid arthritis

  2. Gout

  3. Osteoporosis

  4. Osteo arthritis

Show answer
Correct Option: A
Explanation:
Rheumatoid arthritis is an autoimmune disease that mainly effect joints. It typically results in warm, swollen and painful joints. Secretion of abnormal granules pannus is seen in this disease.
So the correct option is 'Rheumatoid arthritis'.

Gout is due to accumulation of

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Uric acid

  2. Calcium carbonate

  3. Oxalic acid

  4. Lactic acid

Show answer
Correct Option: A
Explanation:
  • Gout is a metabolic disease in which crystals of uric acid gets deposited in joints, tendons and surrounding soft tissues.
  • Symptoms of gout increase irritation, inflammation of joins and tendon tissue, joints become hot red and swollen.
  • Hence gout is due to accumulation of uric disease.
  • So, the correct answer is 'Uric acid'.

Which is not a mental disorder?

disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

  1. Gout

  2. Epilepsy

  3. Neurosis

  4. Psychosis

Show answer
Correct Option: A
Explanation:

Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness and swelling in a joint, usually a big toe.
Epilepsy is a central nervous system disorder in which nerve cell activity in the brain becomes disrupted.
Neurosis is a class of functional mental disorders involving distress but neither delusions nor hallucinations.
Psychosis is a serious mental disorder characterized by ' a loss of contact with reality'.
Therefore, the correct answer is option A.
