DNA stands for:

Deoxyribonucleic Acid
The monomers of DNA are:

Nucleotides
3 Parts of DNA are:
- Phosphate Group
- Deoxyribose Sugar
- Nitrogen Base
4 Types of Nitrogen Bases in DNA are:
- Thymine (T)
- Adenine (A)
- Guanine (G)
- Cytosine (C)
- A pairs with T (Always Together)
- G pairs with C (Great Combination)
Purines are:

Adenine and Guanine
Pyrimidines are:

Thymine and Cytosine
How many hydrogen bonds are between A and T?

Two
How many hydrogen bonds are between G and C?

Three
DNA Replication
- The process in which DNA makes copied of itself.
- This occurs in the nucleus of a cell.
RNA stands for:

Ribonucleic Acid
4 Types of Nitrogen Bases in RNA are:
- Adenine
- Uracil
- Guanine
- Cytosine
Three types of RNA are:
- Messenger RNA (mRNA)
- Transfer RNA (tRNA)
- Ribosomal RNA (rRNA)
mRNA is made in a process called _____.

Transcription.
Transcription occurs in the _____ of the cell.

Nucleus.
The strand of DNA being read during transcription is called the _____.

Coding strand.
Codon (define)
- A group of 3 letters on an mRNA strand.
- Each codon represents an amino acid.
Translation takes place in the _____ of the cell.

Ribosomes.
tRNA drops _____ onto the mRNA.

Anti-codons.
When tRNA deposits anti-codons, this makes _____.

Amino acids.
The chemical formula for a phosphate group is:

PO₄
The 2 functions of DNA are:
- Instructions for the synthesis of all proteins.
- Copies itself to be passed on to offspring.
Function of RNA is:

To assist in protein synthesis.
Translation (define)

A strand of RNA is read one codon at a time and amino acids are deposited to make proteins.
