Read the following and answer any four questions from (i) to (v) given below:DNA replication is a complex multistep process that requires enzymes, protein factors and metal ions. DNA replication in eukaryotes occurs in the nucleus during the S-phase of the cell cycle. It is semidiscontinuous in eukaryotes. in prokaryotes, replication takes place in the cytoplasm. DNA replication in bacteria occurs prior to fission. Nucleoid or viral chromosome is a single molecule of nucleic acid, it may be linear of circular. Nucleic acid in a virus is either DNA or RNA but never both.

  1. Single
  2. Twice
  3. Multiple
  4. None

Turner's syndrome is an example of monosomy. It is formed by the union of an allosome free egg and a normal 'X' containing sperm or a normal egg and an allosome free sperm. 'The individual has 2n = 45 chromosomes (44 + X0) instead of 46. Such individuals are sterile females who have rudimentary ovaries, under developed breasts, small uterus, short stature, webbed neck and abnormal intelligence. 'They may not menstruate or ovulate. This disorder can be treated by giving female sex hormone to the women from the age of puberty to make them develop breasts and have menstruation. This makes them feel more normal.
  1. Number of barr body present in a female with Turner's syndrome is?
  1. 0
  2. 1
  3. 2
  4. < 2.
  1. Turner's syndrome is an example of?
  1. Aneuploidy.
  2. Euploidy.
  3. Polyploidy.
  4. Autosomal abnormality.
  1. Turner's syndrome is a/an.
  1. Autosomal recessive Mendelian disorder.
  2. Autosomal dominant Mendelian disorder
  3. Sex linked Mendelian disorder.
  4. Chromosomal disorder.
  1. Which of the following statements regarding Turner's syndrome is incorrect?
  1. It is a case of monosomy of chromosomes.
  2. The suffering individual is a sterile female, having one 'X' chromosome missing in the cells.
  3. The problem is due to an extra chromosome.
  4. The individual are of short stature.
  1. Assertion: Turner's syndrome is caused due to absence of any one of the X and Y sex chromosome.
Reason: Individuals suffering from Turner's syndrome show masculine as well as feminine development
