The two scientists names are James Watson and Francis Crick.
The first successful cloned frog was created by scientists at the Institute of Biophysics in Moscow, Soviet Union, in 1952. They used a nuclear transfer technique to clone the frog, which was named "Frog Prince."
The scientists Alfred Hershey and Martha Chase conducted a series of experiments at the Carnegie Institute of Washington in 1952, and concluded that the genetic material of a bacteriophage was DNA.
Photo 51, taken by Rosalind Franklin in 1952, played a crucial role in the discovery of the structure of DNA. It provided key evidence that DNA has a helical structure, which was essential for James Watson and Francis Crick to propose the double helix model of DNA. This model revolutionized our understanding of genetics and laid the foundation for modern molecular biology.
Scientists confirmed DNA's role in storing, copying, and transmitting genetic information through various experiments, such as the Hershey-Chase experiment in 1952. They showed that DNA, not protein, is the genetic material that carries hereditary information. Additionally, studies on DNA structure, like Watson and Crick's discovery of the double helix, further solidified our understanding of DNA's crucial role in genetics.
Frog. In 1952, the nucleus of a frog embryo was placed into a donor cell by Robert Briggs and Thomas J. King, pioneering a technique that laid the foundation for modern cloning methods.

your model 42 Winchester was made in 1952.
Could you mean the model 340,not 840?If this is the case,the model 340 was made from 1950-1985,the model 340C was made from 1952-1960,and the model 340V was made in the late 1960,s.The model 340S was made from 1952-1960 also.
I show in my records that savage made a model 340 and a model 340c.The model 340 was made between the years 1950-1985.The model 340C was made between the years 1952-1960.There was also a model 340V which was made in the late 1960,s.The model 340S was made between 1952-1960.
