What are observable traits such as height and size of your feet part of?

The observable traits are part of your DNA, your genetics.


Why aren't acquired characteristics important to the theory of evolution?

Evolution is the accumulation of genetic characteristics that are passed on in a population. Basically, you have to be born with it to pass it on. Whatever you're born with is in your DNA, and your offspring get part of your DNA via sexual reproduction. But if you work out and get big muscles, that's not in your DNA, and so you can't pass it on to your kids. Maybe you can pass on a predisposition towards easily building muscle, but your kids aren't going to born big and buff. Acquired traits don't put themselves on the DNA, and DNA is what's needed to build an organism. Another example: There's a brown cat and a white cat. The white cat stands out a lot against his forest background, and dyes himself brown (I know this isn't realistic). Both survive, one with an inherent characteristic and one with an acquired one. But when they reproduce, the white-dyed-brown cat has white babies, because the dye isn't on his DNA, so he can't pass the brown to his babies.


Why doesn't evolution occur through the inheritance of acquired characteristics?

Because acquired characteristics are not programmed in the DNA; only characterisitics which are genetically programmed are passed on and inherited.


Do you consume DNA as part of your diet?

No, humans do not consume DNA as part of their diet.


Do DNA have cells?

No DNA is part of the cell.


What is the purpose of the ladder marker DNA?

DNA passes through a gel at different speeds depending on its size. The purpose of the ladder marker of a DNA is to make the passing of DNA possible.


Do protons and neutrons have DNA?

No, because they are a part of DNA.

Whether enzyme is bigger or DNA is bigger in molecular size and how do we conclude that?

enzyme is nothing but the protein which is formed from DNA by translation through transcription of a particular region of the DNA . so obviously the DNA is larger than the enzyme in molecular size.


How to interpret DNA gel electrophoresis results effectively?

To interpret DNA gel electrophoresis results effectively, analyze the size and intensity of the bands on the gel. Compare the bands to a DNA ladder to determine the size of the DNA fragments. Higher intensity bands indicate more DNA present. Look for differences between samples to identify variations in DNA size or quantity.


Can the size of a supercoiled plasmid DNA be determined by using standard DNA fragments electrophoresed in parallel?

Yes, the size of a supercoiled plasmid DNA can be estimated by running standard DNA fragments with known sizes in parallel on an agarose gel. By comparing the migration distance of the supercoiled plasmid with the standard DNA fragments, an approximate size can be determined.


Is the chromosome a part of a DNA or is a DNA a part of a chromosome?

The second statement would be more correct.
