a) Under normal conditions E. coli produces three DNA polymerases. State their functional similarities and differences. b) List the other proteins and enzymes involved in DNA replication in E.coli and give their functions.
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.
a) Under normal conditions E. coli produces three DNA polymerases. State their functional similarities and differences.
b) List the other proteins and enzymes involved in
E.coli bacteria are considered prokaryotes, and the prokaryotes exhibit three different types of DNA polymerases that is pol I, II, and III. The DNA polymerase helps in the synthesis of new DNA segments.
