DNA and RNA review
Fill in the blanks:
The shape of DNA is described as a twisted ladder or a ________________
____________.
DNA stands for __________________________________________ and
it is found only in the ______________ of cells (unless the cell is dividing). DNA contains the
instructions for making ___________________. The macromolecule that DNA and RNA
belong to is __________________________ and the monomers that build this macromolecule
are called ________________________. This monomer has three parts to it which are
__________________, __________________, and four different ________________.
The sugar that is found in a nucleotide of DNA is called _____________________________.
The four bases in DNA are adenine, thymine, cytosine, and guanine. We just abbreviate them as
_________________. Chargaff’s rule states that A always bonds with ______ and ______
always bonds with G. The genetic code is, specifically, found in the order of the ___________
within the DNA molecule.
RNA is another nucleic acid that helps to build the protein in your body. RNA stands for
____________________________________________. RNA is different than DNA in a
few different ways. The sugar in RNA is _____________________________. The bases
that are part of a RNA nucleotide include __________________. The “U” stands for
__________ and takes the place of ______________ that was in DNA. So, in RNA, C pairs
with _____ and ____ pairs with A. There are three types of RNA. Messenger RNA
(__________) is used to copy the instructions in ________. Transfer RNA (__________) is
used to bring over the correct ______________________ in the correct _______________.
Ribosomal RNA (___________) is the workbench where ____________________________
are bonded to build the protein.
