1. Nucleic Acids Polymer made of monomers called nucleotides
Nucleotides consist of a 5-carbon sugar, a phosphate group, and a nitrogenous base.
There are two nucleic acids
If the sugar is ribose the nucleic acid is RNA (ribonucleic acid)
If the sugar is deoxyribose the nucleic acid is DNA (deoxyribonucleic acid)
Has atoms of elements C-H-O-N-P
Function: Store and transmit genetic information (heredity)

2. Nucleic Acids

3. DNA’s nitrogen bases

5. DNA is a polymer of nucleotides shaped like a twisted ladder
DNA is a polymer of nucleotides shaped like a twisted ladder. The phosphate of on nucleotide bonds with the sugar of another nucleotide by strong carbon bonds forming the sides of a DNA ladder. Nitrogen bases bond to each other by weak hydrogen bonds forming the rungs (steps of the ladder).

6. DNA is found in the nucleus of a cell
DNA is found in the nucleus of a cell. Since DNA controls cellular activity through coding for proteins, and it is in the nucleus, the nucleus is sometimes called the brain or control center of the cell.

7. DNA
Is a double stranded twisted molecule that can look like a spiral staircse
has the code for making proteins which direct all the cell’s activities
Is made of DNA nucleotides
it is passed on to the next generation of cells so that the next cells can direct their activity
DNA is made by copying DNA by the process called REPLICATION
Replication happens in the nucleus

8. Messenger RNA (mRNA)
Is a single strand copy of some of DNAs information made of RNA nucleotides
It is used to carry the protein code from the DNA (Where is DNA?) to the ribosomes (Where will you find ribosomes?)
it determines which amino acid is used and the order of the amino acids that make up the protein (What structure of a protein is the animo acid sequence?)
mRNA is made by making a partial copy of DNA with RNA nucleotides by the process called TRANSCRIPTION
Transcription happens in the ribosomes

9. Transfer RNA (tRNA)
tRNA has 3 nitrogen bases on one end that code for a specific protein
The other end of tRNA has a specific amino acid attachedd
tRNA
Amino acid
mRNA

10. Also… Nucleic Acids – molecules that store genetic information
Examples: DNA, RNA, (also ATP)
produced in nucleus – replication, transcription
Used to produce proteins, which express traits
Nucleotides – sugar, phosphate, nitrogen base
Build basic DNA nucleotides to show the parts
