DNA polymerase I adds nucleotides to both ends of the RNA primer to the 3' end of the RNA primer to the 5'-end of the leading DNA strand that replicates continuously to the 5' end of the RNA primer in the place of the RNA primer after it is removed
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.
In eukaryotes, DNA replication is semi-conservative, semi-discontinous and bidirectional whereas in prokaryotes it is semi-conservative, bidirectional and continuous . The process of replication in living cells requires a set of enzymes and DNA dependent DNA polymerase is the major one.
Initiation of DNA synthesis always requires a smaller segment of RNA called RNA primer.
