Why is the DNA structure important?

Answer 1

The DNA letters tell us about what you look like, how smart you are, and etc. The letters can be changed / gotten rid of at birth too if you're found with a disease The letters represent the sequence of nucleotides that the DNA molecule carries and is the way genetic information is stored in a cell. "The DNA letters" can be called "genetic information".

Answer 2

The DNA structure is important because it contains the genetic information that determines an organism's traits and functions. Its double helix shape allows for precise replication during cell division, ensuring the accurate transmission of genetic material from one generation to the next. Understanding DNA structure is crucial for advancing fields like genetics, medicine, and biotechnology.

Answer 3

I'm not entirely sure what your question is, in terms of order.

If you meant overall why does it matter, it is because those pieces are our genetic blueprint. The order is still in the process of being figured out (Human Genome Project) but each pair relates back to a specific part of the body. If they were to be switched around, they would come up with an entirely different being. (Think of it like cooking. You can have all the ingredients but if the eggs are added last, it wouldn't make a cake.

As to how far that has a difference, I have no clue. I know that there is very little genetic difference between humans and apes but how does the order affect things? That is something I'm interested in asking now... ---------------------- The order of the nucleotides (for example ACCGATCTACGG) determine the amino acid sequence of protein it encodes. Proteins need the correct amino acid sequence in order to fold and function correctly. Using the previous example, ACCGATCTACGG is transcribed as UGGCUAGAUGCC in mRNA and is translated to Trp-Leu-Asp-Ala. If I take the bases in the original sequence and rearrang them to GCTATAGCACCG, this sequence is then transcribed to CGAUAUCGUGGC, which is translated to Arg-Tyr-Arg-Gly, which is completely different from the original and will likely result in a completely non-functional protein.

Answer 4

Genes are responsible for transferring hereditary information from one generation to the next, and since they are DNA molecules, or segments of them, the structure of DNA provides the key to understanding the physical basis of heredity.
