DNA and Protein Synthesis. Nucleic Acids. Nucleic Acids - Function. Control the processes of heredity by which cells and organisms make proteins. Nucleic Acids – Types . DNA Deoxyribonucleic Acid RNA Ribonucleic Acid. As you know, DNA stands for…. DEOXYRIBONUCLEIC ACID.
All nucleotides have three “parts” in common. They all contain….
PLEASE UNDERSTAND, A NUCLEOTIDE IS A VERY COMPLEX STRUCTURE. IF WE REPRESENTED ALL OF THE ATOMS, IT WOULD LOOK LIKE THIS…
We will use our hands to represent a nucleotide.
The four different Nitrogen Bases for DNA are abbreviated using the following letters….
Using your two hands, please show how you think two nucleotides will/should bond together.
Did you put your hands like this???
In DNA, Adenine always pairs with Thymine using two hydrogen bonds.
In DNA GUANINE always pairs with CYTOSINE using three hydrogen bonds.
Time to use your brain and hands in order to review nucleotide structure and type.
USING YOUR HAND, SHOW ME THYMINE
USING YOUR HAND SHOW ME ADENINE
SHOW ME CYTOSINE
SHOW ME HOW CYTOSINE AND THYMINE BOND TO FORM A RUNG ON THE LADDER
Now that you recognize nucleotide type and structure, it’s time to start building the polymer from these monomers.
In order to make a molecule of DNA, you would need to create many rungs to the DNA ladder.
Look. Many Rungs.
What part of the nucleotide alternates to form the sides of the DNA ladder?
What makes up the “RUNGS” of the ladder?
Stack your hands on top of your partner’s hands building two rungs of the DNA ladder.
If you link enough nucleotides together, the DNA molecule begins to take on the characteristic shape known as the
