The correct answer is: b. The structure of DNA was helical

This photo known as Photo 51 is an X-ray diffraction image of crystallized DNA made by Rosalind Franklin. This photo helped Watson and Crick to define the final structure of DNA molecule. This diffraction pattern was essential for the construction of DNA model and it determined the helical nature of the double antiparallel helix strands.

g Which of the following statements is NOT true? A. Each variable site of a gene tree can be treated as an independent character
Lady bird [3.3K]

Answer:

C. Gene trees are only useful studying the relationships of sequences from different species.

Explanation:

Gene tree traces the evolutionary history of a particular gene. It includes all the events like duplication and speciation. It helps to study the relationship of genes from different species. Often these are orthologous genes which came form the same ancestor and code for the same protein indifferent species. Gene tree also helps to study the relationship of genes in the same species. Often these are paralogous genes which evolved by duplication and code for similar but not identical proteins in the same species. Hence, the statement that gene trees are only useful for studying the relationships of sequences from different species is incorrect.
