In protein synthesis the base sequence of mRNA determines the primary structure of polypeptide chain because
it determine the sequence of alignment of amino acid charged tRNA molecule
there is one to one coding relationship between each base on mRNA and amino acid
each amino acid is defined by a pair of base on mRNA
amino acid molecule align directly on the polynucleotide on mRNA
What do you mean to the mutation in which replacement of a nucleotide occur by another similar type?
Inversion
Transition substitution
Transversion substitution
Insertion frame- shift
Which of the following assumption is not belonging to Hardy-Weinberg principle?
The population size is very large
Random mating is occurring
Natural selection takes place
No mutation occurs
Which of the following rule states that Avian and mammalian forms are generally of higher size in colder region as compared to warmer region'?
Bergmann's rule
Allen rule
Gloger rule
Hardy-Weinberg rule
Abzymes are
catalytic antibodies
neutral antibodies
non-specific antibodies
defermed antibodies
A.
catalytic antibodies
In 1969, William Jencks proposed that antibodies specific for the transition state of a chemical reaction should have catalytic power. This incisive prediction was realised in 1986 when scientists found that antibodies with catalytic nature can be synthesised by using transition state analogue.
Population means
all the animals of a place
all the animals and plants found in an area
human beings in an area
animal/plants of a species living in a specific area
Parthenogene embryos in plants are those which are formed by
unfertilised eggs
fertilised eggs
sporophytic cells
male gametophyte
Multiplication of genetically identical copies of a cultiver by asexual reproduction is known as
aclonal propagation
clonal propagation
vegetative propagation
polyclonal propagation
The gene controlling seven traits in pea studied by Mendel were later found to be located on the following number of chromosomes
seven
four
five
