This next question is good practice to be familiar with thinking about what happens to chromosomes during replication, at the level of DNA sequence. It's not necessarily the kind of question you will find on a test – but is good review. 8. Below we see some double stranded DNA sequence on a chromosome in a diploid organism. 5' GCTTCCCAA- 3'. 3' 5' CGAAGGGTT- a. The organism has an identical copy of this sequence on its homologous chromosome (homozygous). After DNA replication, how many copies of this double-stranded sequence would exist in a cell? Draw the 2 homologous chromosomes with the double stranded sequence shown above, DNA strands labelled with 5' and 3', and centromeres indicated, both before and after DNA replication. It is recommended that you draw the newly synthesized DNA strands in a different colour or pattern to differentiate between old strands and new strands (e.g. old strands as straight lines as shown above and draw the new strands as squiggly lines
