Me which of the following codes for a specific protein? dna gene enzyme chromosome which of the following is single-stranded, found throughout the cell, and has the bases a, u, c, and g? dna rna both dna and rna neither dna nor rna the sequence of the amino acids effects which of the following? the amount of cytoplasm the number of proteins the size of the ribosomes the shape of the protein

1: Gene

2: RNA

3:  The shape of the protein

Explanation:

A gene is a stretch of DNA that codes for a specific protein. Gene is expressed through transcription and translation. RNA is single stranded nucleic acid and have four nitrogenous bases: Uracil, Adenine, Guanine and Cytosine. RNA do not have thymine base. The sequence of the amino acids affects the shape of the protein by affecting its secondary and tertiary structure.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

the endomembrane system i think
