What is DNA

DNA

By PRISCILLA DOMINO

• Deoxyribonucleic Acid

• Made of:

  • Phosphate groups

  • Deoxyribose sugars

  • Nitrogenous Bases

• A series of nucleotides creates 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 float in prokaryotic cells

​

What is DNA?

Multiple Choice

DNA contains the instructions for making ______.

• carbohydrates

• lipids

• proteins

• nucleic acids

Multiple Choice

Which specific part of a chromosome is a section of DNA that carries information on how to make one protein.

• centromere

• chromatid

• nucleotide

• gene

Multiple Choice

What determines the specific traits in an organism?

• The number of carbons in the DNA molecule.

• The number of hydrogen bonds that hold the strands of DNA together. 

• The sequence of nucleotide bases in the DNA molecule.

• The sequence of phosphates along each DNA strand. 

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

What is a nucleotide?

Multiple Choice

What is the molecule in the image?

• Nucleotide

• Deoxyribose Sugar

• Nitrogenous base

• Phosphate

Multiple Choice

What is "A"?

• Nucleotide

• Deoxyribose Sugar

• Nitrogenous base

• Phosphate

Multiple Choice

What is "B"?

• Nucleotide

• Deoxyribose Sugar

• Nitrogenous base

• Phosphate

Multiple Choice

What is "C"?

• Nucleotide

• Deoxyribose Sugar

• Nitrogenous base

• Phosphate

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?

Multiple Choice

If a portion of original DNA is ATTCGA, what will the complimentary strand be?

• TAAGCT

• ATTCGA

• TATTCG

• CGATTA

Multiple Choice

What do the dotted lines between the nitrogenous bases (A,T,C,G) represent in the image provided?
