DNA!

DNA!

By Jodi Edge

​Identify components of DNA, identify how information for specifying the traits of an organism is carried in the DNA, and examine scientific explanations for the origin of DNA

and

recognize that components that make up the genetic code are common to all organisms​

​

• Deoxyrhybonucleic Acid

• Made of:

  • Phosphae groups

  • Deoxyrhybose sugars

  • Nitrogenous Bases

• Series of nucleotides creating a long stranded molecule

• Code for ALL life; from us to the bacteria that make us sick!

• ​Molecule resides in the nucleus of eukaryotic cells and freely floats in prokaryotic cells

​

What is DNA?

Each nucleotide contains a Phosphate, sugar, and nitrogenous base.

​

​Some text here about the topic of discussion.

What is a nucleotide?

Multiple Select

What molecules are in nucleotides?

• Phosphate group

• Protein

• Sugar

• lipid

• Nitrogenous base

These alternate to form the ladder-like backbone of DNA​

What does the sugar and phosphate group do?

Nitrogenous bases are the "code" part of DNA and/or RNA. Their order is what tells the cell what to make and how to do it. 4 bases found in DNA; in RNA U replaces T.

BASES include:

Cytosine

Thymine (DNA ONLY!)

Guanine

Adenine​

​ Uracil (RNA ONLY!!)

​What is a nitrogenous base?

Multiple Select

Which molecules make up the "backbone" of DNA and RNA?

• Sugar

• Phosphate group

• Nucleotide base

Multiple Choice

Why are the nucleotides so gosh darn important? (Careful, all statements are true! Make sure you are picking what makes them IMPORTANT!!!!)

• They hold the DNA together.

• They live in the nucleus.

• This is the chemical part that CODES for life.

• There are 5 different kinds.

Nitrogenous bases "clip" together with HYDROGEN BONDS.

But they can't bond randomly.

Thymine must bond with Adenine

Cytosine must bond with Guanine​

Until RNA has to copy... then Adenine bonds with Uracil (HOW AM I SUPPOSED TO REMEMBER THIS!!!!!)

Remember:

G-CAT!​

What's up with the double strand, and how does it effect coding?​

​NOVELA

TIME!!!!!​

​I'm the G-CAT! The Groovy CAT!
