Question

What role do genes play in inheritance?

Answer 1

genes express proteins and non translated transcripts that are forming and controling the organism. Passage of genes to offspring gives offspring a potential to create these transcripts and proteins.

Explanation:

You can better understand this with the story of rediscovery of DNA as an inheritance material. There main experiment explains it perfectly. Below i explained experiments simply for detailed information please visit:

Griff's experiment: In this experiment two strain of the organism used. R(rough) and S(Smooth) strain. While R strain does not lead to diseased host, S strain cause disease. In the experiment passage of characteristics observed via occurance of illness

Avery Mcload EXP: In this experiment what is passed from S strain to R strain is answered by digesting suspected molecules

Harshey- Chase EXP: In this one, passage of DNAis illustrated by fluorescence tagging.
