5. DNA is made of two strands that are antiparallel. If one strand runs from 3' to 5' direction the other one will go from 5' to 3' direction. During replication or transcription, whatever the process is, it will always follow the 5' to 3' direction using the 3' to 5' directed strand as the template strand. Therefore, if following is the DNA sequence 5'-CCG ATC GCA CAA-3’ a) Using this sequence as template after transcription no protein can be translated. Why? I. Presence of start codon II. Absence of start codon III. Due to mutation b) If you want to start the translation, what change you need in the second codon (from 5' to 3' direction)? I. Substitution of C with G II. No change III. Deletion of C IV. Both I & III

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.
