Assertion: Ribosomes protect mRNA from ribonuclease.
Reason: mRNA is located in the gap between the two ribosomal subunits.


Important Questions on Molecular Basis of Inheritance
Assertion : In prokaryotes, there are three initiation factors used for protein synthesis.
Reason : All the initiation factors have their own functions.

Assertion: The bacteria and other prokaryotes show high adaptability to the changing environment.
Reason: Members of kingdom Monera are efficient in regulating gene expression.

Assertion : DNA found in mitochondria and chloroplast are called prochromosome.
Reason : They are similar to prokaryotic chromosome.

Assertion : Killer strain of Paramecium aurelia can kill sensitive strain.
Reason : If sensitive strain is provided kappa particle, it becomes killer.

Assertion : Scaffold proteins are nonhistone chromosomal proteins.
Reason : They are rich in lysine and arginine.

Assertion : RNA produced during transcription in eukaryotic cells cannot be straight away used in photosynthesis.
Reason : RNA splicing phenomena helps in the removal of exons.

Assertion : Recognition site should be preferably single and responsive to commonly used restriction enzyme.
Reason : In pBR alien DNA is ligated generally in the area of Bam- site of tetracycline resistance gene.
