The process of translation of mRNA to proteins begins as soon as
1. The tRNA is activated and the larger subunit of ribosome encounters mRNA
2. The small subunit of ribosome encounters mRNA
3. The larger subunit of ribosome encounters mRNA
4. Both the subunits join together to bind with mRNA

DNA polymorphism forms the basis of
1. Translation
2. Genetic mapping
3. DNA finger printing
4. Both genetic mapping and DNA fingerprinting

If a geneticist uses the blind approach for sequencing the whole genome of an organism, followed by assignment of function to different segments, the methodology adopted by him is called as:
1. Bioinformatics
2. Sequence annotation
3. Gene mapping
4. Expressed sequence tags

Which one of the following is not a criterion of genetic material? 
1. Should not provide the scope for changes for evolution 
2. Should be able to express itself in the form of Mendelian character 
3. Should be able to generate its replica 
4. Should be stable chemically and structurally

DNA replication is semi-conservative in nature was experimentally proved in eukaryotes by: 
1. Hershey and Chase 
2. Macleod and McCarty 
3. Meselson and Stahl 
4. Talyor and his colleagues 

Which one of the following experiments of Frederick Griffith resulted in the discovery of bacterial transformation? 
1. S-stain(heat-killed) → injected in to Mice  → Mice lived 
2. S-strain (heat killed) + R-strain(live)  →injected in to Mice  → Mice died 
3. S-stain  → injected in to Mice  → Mice died 
4. R-strain  → injected in to Mice  → Mice lived
