I am absolutly 100% biology stupid... I don't understand it, it is like a foriegn language to me... this is my questions.
What are some of the benefits of squeezing so much data into virtually every cell in the body?
· Why did humans not evolve with one central repository of DNA rather than having it replicated throughout the body?
· Assume that the hereditary information carried in genes and DNA is responsible many differences observed in humans and other living things. How could just four different bases in DNA strands be responsible for the almost endless variety found in nature?
You need to be aware that your cells are constantly dying and replenishing/reproducing themselves.
The arrangements of G, C, A and T within the chromosomes is almost infinite.
Does that help you answer some of your questions?
I hope this helps. Thanks for asking.
not this did not answer my question, what are the benefits.
That helped me a lot. Thanks
I understand that biology can seem complicated and overwhelming, but I'll do my best to explain the concepts in a simple manner.
1. The benefits of squeezing so much data into every cell in the body are as follows:
- Efficient storage: The DNA in the nucleus of each cell contains the instructions necessary for the cell to function and replicate. By compactly storing genetic information within the nucleus, cells can easily access and utilize the necessary information for their specific functions.
- Replication: Having DNA replicated throughout the body ensures that every cell carries a complete set of genetic information. This allows for cellular division, growth, and repair.
- Specialization: Different cells in the body have specific functions, and having DNA replicated in each cell allows for specialized cells to carry out their unique roles. For example, skin cells have different functions than muscle cells, and each requires specific genetic information to perform its designated task.
2. Instead of having one central repository of DNA, humans and other organisms have DNA replicated in every cell for a few reasons:
- Efficiency: Having DNA replicated in each cell avoids the need for long-distance communication within the body to access genetic information. This allows for more rapid and independent functioning of cells, which is crucial for survival.
- Redundancy: Replicating DNA throughout the body ensures that even if some cells are damaged or lost, the genetic information is not completely lost. Cells with replicated DNA can replace damaged cells and continue carrying out their functions.
- Adaptation: Having DNA replicated in every cell enables genetic variation and diversity within an organism. This allows for adaptation to changing environments and provides the basis for evolution.
3. Although DNA only consists of four different bases (adenine, thymine, cytosine, and guanine), it is their arrangement in the DNA strands that allows for the tremendous variety found in nature. The specific sequence of these bases determines the instructions for creating proteins, which are the building blocks of life. Proteins carry out various functions in an organism, such as enzymes for chemical reactions, structural components, and signaling molecules. The arrangement and order of these four bases in the DNA strands create different genetic codes, which result in the production of different proteins. Through variations in protein structures and functions, an almost endless variety of traits can be expressed in living organisms.
I hope this explanation helps you better understand these concepts. If you have any further questions, feel free to ask!
