Life in Venus's Atmosphere?

 2020 has been full of strange news so far, but perhaps some of the strangest could be the possibility of life in Venus's atmosphere. On the surface of the planet, it's hot enough to melt lead. However, scientists have detected phosphine in the atmosphere at concentrations high enough to suggest the gas is being made by anaerobic bacteria in the atmosphere. (Venus's atmosphere is mostly carbon dioxide.) It's not definite proof, and the phosphine could be produced by some unknown method, but it is a tantalizing notion. Here's one of the articles about this discovery. 

If there is life on Venus, does it use DNA and the same genetic code as life on Earth does? Does it use the same basic biochemistry? Is there the possibility of multicellular life? How would it influence science fiction to know there is life on other planets? These are just a few of the questions that I'd want answered. What are yours? Feel free to share them in the comments.

Many of us write about a galaxy far, far away, so we already believed there was life out there. Living in the atmosphere, Venus' life would have to be really small. Or just really light.

Can you imagine if it's a completely different makeup than us?
