Use the numbers below to indicate the correct order of events (from left to right) during the process of translation initiation in bacteria. large ribosomal subunit binds to the complex. IF3 is released. The small ribosomal subunit associated with IF1, IF2, and IF3 binds to the Shine-Dalgarno sequence on the mRNA. tRNA charged with f-methionine binds to the AUG codon at the P site. IF1 and IF2 are released, leaving the A site available for the second charged-tRNA to bind the codon at the A site. 3 1 5 4 2 2 1 4 5 3 1 3 5 2 4 3 4 2 1 5 4 2 1 3 5
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
Use the numbers below to indicate the correct order of events (from left to right) during the process of translation initiation in bacteria.
- large ribosomal subunit binds to the complex.
- IF3 is released.
- The small ribosomal subunit associated with IF1, IF2, and IF3 binds to the Shine-Dalgarno sequence on the mRNA.
- tRNA charged with f-methionine binds to the AUG codon at the P site.
- IF1 and IF2 are released, leaving the A site available for the second charged-tRNA to bind the codon at the A site.
