They can also serve as an excellent jumping-off point for more complex biological topics. DNA polymerase enzymes attach free nucleotides to the open strands, following base pairing rules. Late stage tumors show evidence of primarily the lagging strand of the replication fork acquiring APOBEC-induced mutations presumably due to the longer time that DNA remains single-stranded and that transformed cells often have genomic instability as a hallmark, which may mean that replication forks often become stalled, exposing even more ssDNA (12–17, 19–20). All rights reserved. In the elongation process, the original DNA strand is taken as a guide that DNA polymerase follows all the way. As part of the DNA replication activities, DNA polymerase gets into the picture and enlarges each exposed strand by adding more nucleotides to it. Students will also analyze each DNA nucleotide to identify and describe the 3 parts found on adenine, cytosine, guanine, and thymine. During replication, these strands are separated. Have DNA polymerase bring bases to the leading strand. DNA polymerase adds the gummy bears in fragments (Okazaki fragments) to the 3' to 5' end.
