Explanation:
James Watson and Francis Crick, along with the help of Rosalind Franklin's X-ray crystallography data, are credited with first identifying the structure of DNA as a double helix.
The identification of the structure of DNA as a double helix is one of the most significant discoveries in the history of biology. In 1953, James Watson and Francis Crick, both scientists at the University of Cambridge, proposed the double helix model for DNA based on their understanding of its molecular properties and the X-ray crystallography data provided by Rosalind Franklin and her colleague Maurice Wilkins.
Rosalind Franklin, a talented biophysicist, used X-ray crystallography to study the molecular structure of DNA fibers. Her X-ray diffraction images, including Photo 51, provided crucial insights into the helical nature of DNA and its dimensions. Although she did not directly contribute to the final model proposed by Watson and Crick, her work was instrumental in guiding their understanding of DNA's structure.
In April 1953, Watson and Crick published their landmark paper in the journal Nature, titled "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid." In this paper, they described the double helix model of DNA, with the two strands forming a twisted ladder-like structure, and the base pairs holding the strands together like rungs on the ladder.
The identification of DNA's structure as a double helix provided a crucial foundation for understanding how genetic information is stored and transmitted in living organisms. This discovery paved the way for advancements in genetics, molecular biology, biotechnology, and other fields, transforming our understanding of life at the molecular level and earning Watson, Crick, and Wilkins the Nobel Prize in Physiology or Medicine in 1962.

Answer:
Friedrich Miecher was the Swiss chemist who first identified DNA in 1860. It was first identified in the nuclein which is found inside nuclei of the human white blood cells. The nuclein was later on named as nucleic acid. The type of nucleic acid was identified as deoxyribonucelic acid.
b. involves much less DNA.
c. can start in many different places on a sequence at the same time.
d. starts from a single point.
Alleles for sex-linked traits are inherited in such a way that they are passed from parents to offspring on the X and Y chromosomes.
Generally, sex-linked traits are traits or genes that are found on the sex chromosomes only. In humans, females have XX sex chromosomes while males have XY sex chromosomes.
