There are many differences between DNA replication happening during mitosis in a Douglas fir tree
growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a
forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence
Repeat. Complete the following table that compares the two DNA replication events in terms of the
primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value

Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward
