Mitochondria and chloroplasts have their own DNA.


Why was the revelation of rosalind Franklin James watsonand francis crick so importana?

The revelation of Rosalind Franklin's X-ray diffraction images of DNA was crucial for James Watson and Francis Crick as it provided key insights into the double helix structure of DNA. Franklin's work revealed the helical nature and dimensions of DNA, which were fundamental to understanding how genetic information is stored and replicated. This collaboration, albeit uncredited at the time, ultimately led to the breakthrough discovery of the DNA structure, revolutionizing the fields of genetics, biology, and medicine.


Less hyperchromic shift?

A less intense hyperchromic shift indicates a smaller increase in DNA absorbance, suggesting a reduced DNA concentration or increase in single-stranded DNA compared to double-stranded DNA. This shift can result from factors such as DNA degradation, RNA contamination, or incomplete denaturation of DNA during spectrophotometric analysis. Further investigation may be needed to determine the specific cause of the reduced hyperchromic shift.


What are three theories that have changed due to new evidence?

One significant theory that changed due to new evidence is the theory of plate tectonics, which was bolstered by discoveries in seafloor spreading and the magnetic alignment of rocks. The understanding of the origin of the universe has evolved with the Big Bang theory gaining support from cosmic microwave background radiation discoveries. Additionally, the theory of evolution has been refined with the introduction of genetics, particularly through the understanding of DNA and genetic mutations, providing a clearer picture of how species adapt and evolve over time.

Which scientist used X-ray diffraction to find that DNA has a spiral shape?

Rosalind Franklin used X-ray diffraction to capture images of DNA that provided crucial evidence of its helical structure. Her famous Photograph 51 revealed the pattern of X-ray diffraction that indicated DNA's spiral shape, which later contributed significantly to the discovery of the DNA double helix by James Watson and Francis Crick.

How do they use DNA evidence today?

DNA evidence is used in criminal investigations to link suspects to crime scenes, identify victims, and exonerate innocent individuals. It is also used in paternity testing, identifying bodies in mass disasters, and studying genetic inheritance and evolution. DNA evidence is a powerful tool due to its accuracy and unique nature.
