Wow all of what i can say all the respect to you you made me understand the topic not memorize it with no understanding and forget it the next day at first i thought it's a pretty hard subject but your simplification of the topic with pictures showing us the bridges between the bacteria and the experiment that was done made me understand what's going on thank you so much please share more videos we need more people like you i'm an auditory person and love learning from watching videos you deserve a big like thx a lot again
i got a question,... in the the example conjjugation between the 2 auxo trophs it ended up that after mixing them they passed traits to each other,,, so gentic material should have transferd from one to other.... and at the end of the vidio u mentiond that conjugation occur by transfering one strand of episome how is that
so in the example of 2 auxotrophs if one strand of episome is the one transferd does this mean that it contain the genes or copies of the aminio acid synthesizing genes
DNA is passed from the cell with the episome, F+ (or integrated episome in the case of HFR cells), to the F- cell. Transfer is directional. However, DNA is double stranded. The donor cell transfers one strand and keeps the complementary strand. After the transfer, both donor and recipient cells convert the single stranded DNA to double stranded. So both now have a complete episome.
