Nucleic Acids Flashcards
RNA Function
- Primary job is to make proteins
* transports info by fitting through the nuclear membrane
DNA function
- Contains genetic code, means it controls how you act & look
- Provides info for the cell
DNA location
• only in nucleus
RNA location
• found in the nucleus, cytoplasm and ribosomes
DNA Structure
- Double helix
* 2 strands wound together with nitrogenous bases between each strand
DNA monomers
• called nucleotides with a deoxyribose sugar, a phosphate group and 1 nitrogenous base
RNA structure
• single strand with only half of the nitrogenous bases
RNA monomers
• called nucleotides with a ribose sugar, a phosphate group and one nitrogenous base
