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 smaller subunit of ribosome encounters mRNA |
3. | The larger subunit of ribosome encounters mRNA |
4. | Both the subunits join together to bind with mRNA |
The first phase of translation is:
1. Recognition of DNA molecule
2. Aminoacylation of tRNA
3. Recognition of an anti-codon
4. Binding of mRNA to ribosome
Under which of the following conditions will there be no change in the reading frame of the following mRNA?
5'AACAGCGGUGCUAUU 3'
1. | Deletion of GGU from 7th, 8th and 9th positions |
2. | Insertion of G at the 5th position |
3. | Deletion of G from the 5th position |
4. | Insertion of A and G at the 4th and the 5th positions respectively |
