What evidence is there to support that this code carries hereditary instructions?

Im studying about DNA and its 4 bases which are adenine, cytosine, guanine, and thymine. The question I need to figure out is above. What does it mean by code?

What evidence is there to support that this code carries hereditary instructions?
it is referring to teh genetic code, which is the sequence of adenines, cytosines, guanines, and thymines.





Basically, all living things have DNA. It is the same molecule for every living things. However, every organism's DNA has a different order of A's, T's, G's, and C's. This is why it's called a genetic code, because every species, every organism has a unique sequence of A's, T's, G's and C's, and that sequence is what makes that organism that organism.
Reply:code is a nice word for system, generally used when that system isn't obvious or evident. Thus, genetic code! now the evidence. Well, just the fact that just us humans show mutations passed on my heredity. You have a bad diet, your skin turns white with lack of melonin and if you get some sun you actually turn it into vitamin D. To much sun and your skin turns black as a defense, too much heat and you get tall and lanky like the Masai in africa. If its cold your body shortens and you develope a greater fat to mass ratio for insulation like the eskimos. Yeah, I think there might be a little evidence for hereditary code transmission between generations.
Reply:A code is a system for storing information to be used later. A computer program is an example of code. Computers use base-2 or binary code. DNA uses base-4 (literally). Humans have ten fingers and so everyone on earth counts by 10s, with is base-10. DNA code is read by organic molecules sequentially, just as computers read their code sequentially. In computers this causes the CPU to turn on or off certain bits in the hardware, and in DNA the code is used to turn on (produce) or turn off certain proteins. Another way to think of code is any language that is not human (speech).
Reply:"the code" is short for "the genetic code"





Most enzymes (the things that make or break down things in your body) are made of protein.





The proteins are made of amino acids. The cells know which amino acids to put in what order based on 3 letter groups (codons) of RNA bases.





The DNA bases make RNA bases.





To recap: DNA --%26gt; RNA--%26gt; Protein.





How do we know this? Scientists can sequence DNA. For example, it is a well documented fact that sickle cell anemia is caused by nonfunctional hemoglobin (a complicated protein). People without sickle cell anemia and people with sickle cell anemia have a single base pair change in their hemoglobin genes.
