  1. In lower one third part of oesophagus both Myenteric and Meissner's plexus are absent

  2. Carboxypeptidase is exopeptidase acting on 'N' terminal end of peptide chain

  3. Galactosemia is metabolic genetic disorder due to deficiency of the enzyme uridyl transferase

  4. Nucleotidase and nucleosidase enzymes are present in pancreatic juice

Show answer
Correct Option: C
Explanation:
  • Here, option (C) is correct as Galactosemia is metabolic genetic metabolic disorder due to deficiency of the enzyme uridyl transferase.
  • While, carboxypeptidase is a protease enzyme that acts on 'C' terminal end of a protien or peptide.
  • And, in pancreatic juice trypsin, amylase and lipase are present.

Mark the correct statement (w.rt. sickle cell-anaemia) - 

biology keeping diseases away diseases caused by changes in lifestyle diseases and toxic substance non-infectious diseases

  1. Homozygous individuals for $Hb^s$ are apparently unaffected

  2. Heterozygous individuals exhibit sickle-cell trait

  3. Heterozygous individuals are affected as well as carrier

  4. Homozygous individuals for $Hb^A$ show the diseased phenotype

Show answer
Correct Option: A

The most basic amino acid is

biology keeping diseases away diseases caused by changes in lifestyle diseases and toxic substance non-infectious diseases

  1. Arginine

  2. Hisstidine

  3. Glycine

  4. Glutamine

Show answer
Correct Option: A
Explanation:

Glutamine and Glycine are not basic amino acids. Only Arginine and Histidine are basic amino acids. Histidine is weakly charged under physiological ph. Hence, Arginine is the most basic amino acid. 

So the correct option is 'Arginine'.

What part of hemoglobin is affected in sickle cell anaemia?

biology keeping diseases away diseases caused by changes in lifestyle diseases and toxic substance non-infectious diseases

  1. $\alpha$-polypeptide chains

  2. $\beta$-polypeptide chains

  3. Both $\alpha$- and $\beta$- polypeptide chains

  4. None of these

Show answer
Correct Option: B
Explanation:

Hemoglobin has four chains: two alpha chains and two beta chains with heme and iron part along with oxygen. There are some hydrophobic substances (water-hating) present on the surface of proteins. These hydrophobic residues forms cluster and pocket-like structure on the surface of beta chains. These pockets are responsible for diseases like sickle cell anemia also in the beta chain the position of glutamic acid at sixth place in the chain is replaced by valine leading to the shape of red blood cells to be sickle-like due to loss of oxygen.

So, the correct option is 'Beta-polypeptide chains'.

  1. Proteus morganii

  2. Borrelia bacteria

  3. Bacillus anthracis

  4. Trichinella spiralis

Show answer
Correct Option: C
Explanation:
Anthrax is an infection that is caused by the bacteria Bacillus anthracis. These bacteria form spores that are hard-shelled, dormant versions of the bacteria. Spores are the form of the bacteria that cause infection. They can survive in the soil for many decades. Anthrax most commonly occurs in animals such as pigs, cattle, horses, and goats, but it can also infect people.
So the correct option is  'Bacillus anthrcis'
