Restriction enzymes and ligase enzymes. Since the fragments are now inside the bacterial cells, each time when the bacteria divide, the inserted DNA fragments also divide and produce many identical copies. Clone-by-clone Method 2. Next, the assembly of larger fragments into the chromosome takes place according to the genome map. 2. … Last Updated on January 4, 2020 by Sagar Aryal. Method # 1. Due to the larger size of it and the structural complexity of the eukaryotic genome, the method can not work accurately all the time. “DNA sequencing is a method used for determining the sequence and order of nucleotides present in particular DNA sequence.” DNA sequencing methods available nowadays are quite accurate, fast and reliable. In contrast, clone by shotgun sequencing does not follow these two steps; it randomly breaks up DNA sequences into many small fragments and reassembles the sequence by observing the overlapping regions. Hence, this is the key difference between clone by clone sequencing and shotgun sequencing. So, this is the key difference between clone by clone sequencing and shotgun sequencing. Initially, the entire genome is fragmented into varying sizes from 20 kilobases to 300 kilobases. Therefore, clone by shotgun sequencing has become a reliable cheaper sequencing method that can be performed faster. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. Clone-by-clone sequencing. However, whole genome sequencing should not be confused with whole exome sequencing because whole exome sequencing only analyzes less than 1% of the genome. But, the disadvantage of this sequencing method is that it is time-consuming to generate genome maps and making clones. Side by Side Comparison – Clone by Clone Sequencing vs Shotgun Sequencing in Tabular Form Both clone by clone sequencing and shotgun sequencing are two methods of genome sequencing. 1. Clone by clone sequencing method involves mapping of chromosomes and cloning prior to sequencing while clone by shotgun sequencing omits both chromosome mapping and cloning steps during the sequencing.
