James Watson Influences

Influential People who contributed to Genetics:
James Watson:
James Dewey Watson is a Nobel Prize-winning biophysicist and researcher, who is credited with co-discovering the the double-helix structure of the deoxyribonucleic acid (DNA) in 1953 with Francis Crick. Crick and Watson’s first efforts towards learning the structure of the DNA came up with many attempts, but it eventually concluded in the spring of 1953. Their research portrayed the DNA model pulling forth the double-helical configuration, which resembled a flexible ladder. Their research also showed how the DNA molecule could duplicate itself, which eventually answered one of the most brought-up fundamental questions in the field of genetics. Both Crick and Watson had the honor to publish their discoveries in “Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid” in April-May 1953 to great acclaim and praise.
Johann Gregor Mendel:

He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next. Mendel’s Laws of Heredity stated that each inherited trait is defined by a gene pair, genes for different traits are sorted separately so that the inheritance of one trait is not dependent on the inheritance of the other, and that an organism with alternate forms of a gene will express the dominant

    Mendel studied genetics using flowers and pea plants. In a monohybrid, concerning one trait, cross, he crossed a purple (PP) plant with a white (pp) plant, and the offspring were all purple (Pp). He also crossed yellow, smooth peas (YYRR) with green, wrinkled peas (yyrr), which is a dihybrid cross because it involves 2 traits. The offspring of the cross, called F1 offspring because they are the first generation, resulted in 100% round (Rr) and yellow (Yy). The offspring were then intercrossed, and the offspring (F2 generation) resulted in 9:3:3:1 round and yellow (RRYY), round and green (RRyy), wrinkled and yellow (rrYY), and wrinkled and green…

    Gregor Mendel was a scientist from Moravia who became famous for founding the science of genetics. He worked with cross breeding pea plants, focusing on several different characteristics. When he found that breeding a green and yellow pea plant, always turned out with yellow colored offspring, he ended up making the terms "dominant" and "recessive". Sadly, Mendel's work wasn't found important until decades later in the 20th century, but the things he discovered are still important to us today. There are plenty of different qualities that make a good scientist, but some are more important than others.…

    Classical genetics refers to the method of genetics that leads the appearance of molecular genetics, which give us the information of the structure and the function of the genes at a molecular level. Classical genetics, keeps the same basis for all other topics in genetics, firstly the method where genetic traits are transmitted in plants and animals. These traits are classified as dominant recessive intermediate. Also the traits are either sex-linked or autosomal Classical genetics began with Austrian monk Gregor Mendel, who traced the inheritance patterns of certain traits in pea plants and showed they could be described mathematically Mendel’s laws. Mendel published it in 1865, Experiments on Plant Hybridization, this did not get noticed…

    Next is Maurice Wilkins. Wilkins has more of a role in the discovery of the double-helix because he worked directly with the X-ray diffraction machine that would eventually produce Photo 51. Even though his name is not mentioned as much as Crick and Watson, Wilkins was one of the main reasons that the double-helix structure was discovered. He actually took Photo 51 from Rosalind Franklin unbeknownst to her and showed it to Crick and Watson. They immediately realized the significance of the X-ray.…

    Deoxyribonucleic acid (DNA) is the hereditary material. It is a polynucleotide and is a double helix composed of two strand that run in opposite direction1. Each strand of DNA consist of a sugar molecule (deoxyribose), nitrogen base (adenine-A, guanine-G, thymine-T and cytosine-S) and a phosphate group. Adenine and guanine are double-ringed molecules known as purines while thymine and cytosine are single-ringed molecules known as pyrimidines1. Within the DNA molecule, the sugar molecules are joined to each other by 3’-5’ phosphodiester bonds where the 3’ carbon of a sugar molecule is connected to the 5’ carbon of the next sugar1.…

    In the 1920s, the field of genetics saw many groundbreaking discoveries. The research of scientists such as Thomas Hunt Morgan and Hermann Joseph Muller proved the existence of chromosomes and genes as well as showed how mutations can be influenced and passed on to offspring. Geneticists from this decade used study results to form a more complete understanding of previously constructed theories. Genetic research in the 1920s significantly advanced scientific thinking and understanding regarding heredity and evolution of species.…

    Of the four organic macromolecules deoxyribonucleic acid, or DNA, is a nucleic acid. DNA is a double-stranded molecule comprised of numerous nucleotides covalently bound together. Nucleotides contain a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases. The four nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C). To construct DNA’s double helix, hydrogen bonds form between two complementary nitrogenous bases.…

    Remarkable scientists Francis Crick and Maurice Wilkins had been the first to fully understand the double helix structure of deoxyribonucleic acid, commonly known as DNA. In addition, the discovery of the double helix structure of DNA also allowed for both men to exceptionally win the noble prize in physiology or medicine in the year of 1953, when determining the body of deoxyribonucleic. Friedrich Miescher first identified and isolated deoxyribonucleic acid. DNA is carried in living organisms, such as animal, plants and other living organisms, and is found in even multiple viruses. Deoxyribonucleic acid is a molecule, which plays the central role in carrying most of the genetic instructions to create development, reproduction as well as function.…

    Mendelian inheritance is centered around three laws discovered by Gregor Mendel. First is the law of segregation which states that during the formation of gamete the two allele pairs separate randomly. The second law is independent assortment which states during gamete formation each pair of the allele will segregate independently of the rest of the pairs of the chromosomes. The third law is the law of dominance which is that alleles can be dominant or recessive with the expression of the dominant trait when a minimum of one dominant allele is present. Mendel described inheritance as the passing of genetic information from one generation to its offspring what can now be termed as a gene.…

    The laws of heredity discovered by G. Mendel are similar for all complex life creatures and he concluded that genes come in pairs one from each parent inherited as distinct units. Also, the mathematical patterns of inheritance as well as genes segregation and their appearance in the offspring as dominant or recessive traits were determined during his genetic experiments with pea plants and outlined three laws oh inheritance. First, the Law of Dominance is expressed where one allele dominates over recessive one. For instance, during the experiment with the pea plants, the parents were both homozygous (with identical forms of alleles YY and gg.…
