Multiple choice zoology genetics of the future hgp and dna fingerprinting dna fingerprinting human genome project and dna fingerprinting

DNA fingerprinting is useful for the study of

  1. Forensic science

  2. Identity

  3. Relationship

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

DNA fingerprinting is a method used in the identification of the genetic information (DNA) in a person's cell. It is a forensic technique used to identify an individual by the characteristics of the DNA. It is also useful to identify the identity and relation of an individual with others.

  5. I, II, and III
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The polymerase chain reaction (PCR) is a technique used in molecular biology to amplify a single copy of DNA to millions of copies of a particular DNA sequence. 
Molecular cloning is a method used to assemble recombinant DNA molecules and to direct their replication within host organisms to increase the number of recombinant DNA molecule. Here, the DNA can be cloned in a plasmid (extracellular DNA).
Thus, the correct answer is option C.

Which of the following is not required for any of the techniques of DNA finger printing available at present

  1. DNA-DNA hybridisation

  2. Polymerase chain reaction

  3. Zinc finger analysis

  4. Restriction enzymes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
A zinc finger is a small protein structural motif that is characterized by the coordination of one or more zinc ions (Zn2+) in order to stabilize the fold. This proves that it does not require any DNA fingerprinting techniques.
So the correct option is 'Zinc finger analysis'.

Classification system given by Linnaeus was based on 

  1. Androecium structure

  2. Flower arrangements

  3. Leaf morphology

  4. Plant habit
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Carolus Linnaeus is considered as the 'Father of Taxonomy'. He developed a way to name and organize species. 
  • Linnaeus’s artificial system of classification was based on the androecium structure. The significance of flower and fruit structures was first recognized by him. He emphasized the basic numerical characteristics of sexual parts i.e., stamens and carpels. Thus the Linnaeus system is also known as a sexual system.

So the answer is 'Androecium structure'.

Oswald Tippo placed slime molds in

  1. Cyanophyta

  2. Chlorophyta

  3. Phaeophyta

  4. Myxomycophyta
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Oswald Tippo, University of Illiniois 1942, classified plant kingdom into two sub-kingdoms: Thallophyta (thalloid plant body without distinct alternation of generations) and Embryophyta (organ level differentiation of plant body with regular alternation of sporophyte and gametophyte generations). The sub-kingdom thallophyta was divided into 10 phyla: Cyanophyta (Blue green algae), Euglenophyta (Grass green algae), Chrysophyta (Yellow green algae), Chlorophyta (Green algae), Pyrrophyta (Golden brown algae), Phaeophyta (Brown algae), Rhodophyta (Red algae), Schizomycophyta (Bacteria), Myxomycophyta (Slime molds) and Eumycophyta (True fungi). Thus, the correct answer is option D.

'Elements de Botanique' was written by

  1. Vaillant

  2. Tournefort

  3. Micheli

  4. De Bary
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

'Elements de Botanique' was written by Tournefort. The book aimed to define the concept of the genus for plants. It made a clear distinction between genus and species. it also helped in binomial nomenclature, where the genus name forms the first part of the binomial species name for each species within the genus.

So, the correct answer is option B.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • All organisms live their life for a definite time period. 
  • The lifespan of various organisms shows wide variation. For example, the carp (Cyprinus) is a long-lived fish, with a life-span of 40 to 50 years, the average lifespan of a wild king cobra is about 20 years, 
  • turtles and tortoises generally have the longest lifespans of any animal and some individuals are known to have lived longer than 150 years and swans can live for over 100 years.
  • Therefore, the correct answer is option A.

The scientific name of a species 'X' was given by scientist in 1960 as 'P' and another scientist gave another name to the species in 1990 as 'Q'. Which is considered as valid name?

  1. P.

  2. Q.

  3. Both P and Q.

  4. None of them.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

According to the principle of priority in the International Code of Nomenclature, the earliest validly published name for a taxon is the correct one. Since 'P' was published in 1960, it takes precedence over the name 'Q' published in 1990.

Practical purpose of taxonomy or classification is to

  1. Facilitate the identification of unknown species.

  2. Explain the origin of organisms.

  3. To know the evolutionary process.

  4. Identification of medicinal plants.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Taxonomy is the science of classification of organisms and includes identification and nomenclature based on the description of characteristics. Taxonomy, therefore, helps to identify the unknown species. Thus, the correct answer is option A.
