Batches of 200,000 reads of (A+T)-rich DNA were generated and new genome assemblies were reassessed.
After four such batches were added to the assembly, representing about 30% of the data, coverage of the (A+T)-rich regions had improved to 6-fold and the N50 (N50 is the contig size where 50% of the genome sequence is in contigs of size N50 or larger) of contigs had doubled to over 30 kilobases (kbstatistics adequate for gene predictions and analysis. In total, 1.8 gigabases (Gb) were assembled, 7.5 coverage of the (clonable) 236 megabase (Mb) honeybee genome

i am supposed to make a mitosis flipbook. for interphase i have to draw 2 diagrams, 3 diagrmas for prohpase, metaphase, anaphase, and telpphase, and 1 for cytokinesis. in the instructions is says the first oval in each phase should show the location of the organelles at that stage. use the extra ovals to show the movement of the organelles between stages.

what should i put in each oval? i can only find one diagram for each phase but i am suppposed to make like 3 for eeach one. does anyone know where i can find like 3 diagrams for each phase?
