Just use single quotes:

str='$(wget -q -O- http://169.254.169.254/latest/meta-data/instance-id)'

if you want interpolation there are two methods, you can append various single quoted strings:

str='$(mkdir'$1')'

or, you can escape the dollar signs you want literal and use double quotes:

str="\$(mkdir $1)"
