How did Watson and Crick learn about Chargoff's rules?

Chargaff explained his findings and research to Watson and Crick at Cambridge.

Explanation:

Watson and Crick met Erwin Chargaff at Cambridge in 1952, where he explained his research and findings to them. His rule of parity, or 1:1 rule, stemmed from his discovery of guanine's equal ratio in pairing with cytosine.

Watson and Crick went in to use Chargaff's findings and the work of the researcher Rosalind Franklin as a basis for their work on DNA's double-helical structure.

explanation:

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
