During replication of DNA, its two strands separate. Each of these serves as a template for the formation of new strands. Such type of replication is called:
Non-conservative
Semi-conservative
Flexible
Conservative
The genes present on the same chromosome are called linked gene. This phenomenon is called:
Parental gene
Recombinant gene
Autosomes
Linkage
Protein synthesis in an animal cell takes place
only in the cytoplasm
in the nucleolus as well as in the cytoplasm
in the cytoplasm as well as in mitochondria
only on ribosomes attached to a nucleus
How many types of genetically different gametes will be produced by a heterozygous plant having genotype AABbCc?
Two
Four
Six
Nine
A mutant strain of T4 -bacteriophage R-II, fails to lyse the E. coli, but when two strains R - IIx and R - IIy are mixed then they lyse the E.coli. What may be the possible reason?
Bacteriophage transforms in wild
It is not mutated
Both strains have similar cistrons
Both strains have different cistrons
The ratio obtained from a test cross is called:
Back cross
Monohybrid test cross
Dihybrid test cross
Test cross ratio
A and B genes are linked. What shall be the genotype of progeny in a cross between AB/ab and ab/ab?
AAbb and aabb
AaBb and aabb
AABB and aabb
Genes that are involved in turning on or off the transcription of a set of structural genes are called
polymorphic genes
operator genes
reductant genes
regulatory genes
If Mendel had studied the seven traits using a plant with 12 chromosomes instead of 14, in what way would his interpretation have been different?
He would have mapped the chromosome.
He would have discovered blending of incomplete dominance.
He would not have discovered the law of independent assortment.
He would have discovered sex-linkage.
A test cross involving two traits is known as:
All of these
