DNA

mRNA

rRNA

tRNA

DNA is made up of

molecules called

nucleotides. Each

nucleotide has a

phosphate group, a

sugar group and a

nitrogen base.

The four types of

nitrogen bases are

adenine (A), thymine

(T), guanine (G)

cytosine (C)

mRNA, is

single-stranded. It

also contains the

five-carbon sugar

ribose in its

background rather

than deoxyribose,

and includes the

nucleotide base:

adenine (A), uracil

(U), guanine (G)

cytosine (C)

It has two subunits, and

3 binding sites : A, P,

and E.

tRNA are floating

molecules that are

attached to a amino acid

on one side and

anticodons on the other.

Differences

Similarities

1-DNA is double stranded, RNA is single stranded.

2-DNA contains a pentose sugar Deoxyribose but RNA

contains the pentose sugar Ribose.

3- RNA is made in the nucleus, but can travel outside of

it, DNA is limited to the nucleus,

4-DNA has a base called Thymine, Instead, RNA has

Uracil. thymine pairs with adenine in DNA but uracil

pairs with adenine in RNA.

5-There is only one type of DNA but 3 kinds of RNA

(messenger mRNA, transfer tRNA and ribosomal rRNA)

1- DNA and RNA are both made up of monomers called

nucleotides.

2- DNA and RNA both have pentose sugars.

3- DNA and RNA both have 3 common bases called:

Adenine, Cytosine and Guanine.

4- DNA and RNA both have a phosphate groups in

their nucleotides.

5- DNA and RNA both have the base pair of Guanine

and Cytosine.

6- Both are necessary for the cell to produce proteins.

7- DNA makes mRNA which then is translated into

protein.

DNA carries information in a sequence of base pairs of its nucleotides which are:

adenine (A), thymine (T), guanine (G) and cytosine (C).And the type of sequence in DNA

decides the type of sequence in the RNA and this decides the types and order of amino

acids in proteins.

Each one of 3 letter groups of RNA nucleotides code is for a specific amino acids.
