A catchy logo for an educational project ‘Let’s Talk Biology’

C'est ce que Let’s Talk Biology recherchait dans leur logo design

Logo for educational company ‘Let’s Talk Biology’ aimed at educational videos for biology Students. This is a subset of my main company ‘Let’s Talk Dr’ (www.letstalkdr.com). I want a dynamic logo which is catchy. The colours should be two tones of green (light and dark) with a biology theme (study of human behaviour and organisms). Similar to the Let’s talk Dr logo I like the idea of two symbols intertwined (speech bubbles intertwined) and perhaps woven in with symbols of DNA between them. I will put some symbols as references but would like to see what you come up with also.
I definitely want the two speech bubbles so it links to my previous company logo Voir plus
