DNA and RNA

DNA structure

double stranded, uses deoxyribose sugar

DNA function

to create a genetic code for transmission of inherited traits

RNA structure

single stranded, uses ribose sugar

RNA function

to copy the DNA strand and send it out of the nucleus to ribosomes to create proteins for the body

Types of RNA

messenger, transfer, Ribosomal

mRNA

a copy of DNA of a gene

tRNA

carries the amino acids to the ribosome to allow protein synthesis to occur

rRNA

primary component of the ribosome and helps polypeptides form
