Question

open-ended questions: answer the following questions in complete sentences.

1. in your own words, explain why the discovery of dnas structure was important to science.
2. describe how the nitrogenous bases in dna pair up with each other.
3. why is rosalind franklin important to the history of dna?

Explanation:

1. The discovery of DNA's structure was important to science because it provided a fundamental understanding of how genetic information is stored, replicated, and passed on. This knowledge has led to advancements in fields such as genetics, medicine, and biotechnology.
2. In DNA, the nitrogenous bases pair up in a specific way. Adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This complementary base pairing is crucial for DNA replication and the transmission of genetic information.
3. Rosalind Franklin is important to the history of DNA because her work, particularly her X-ray crystallography images of DNA, provided crucial evidence for the double-helix structure of DNA. Her contributions were essential for the discovery of DNA's structure by Watson and Crick.

Answer:

1. The discovery of DNA's structure was important to science as it offered a fundamental understanding of genetic information storage, replication, and transmission, leading to advancements in genetics, medicine, and biotechnology.
2. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G) through complementary base pairing, which is vital for DNA replication and genetic information transfer.
3. Rosalind Franklin is important to the history of DNA because her X - ray crystallography images of DNA provided crucial evidence for the double - helix structure, which was essential for Watson and Crick's discovery.
