What are chromosomes?
What are chromosomes?
A thread-like structure found in the nucleus of every human cell. Each cell has 23 pairs of chromosomes.
What is DNA?
What is DNA?
The blueprint of life. It stores the instructions for building and maintaining an organism.
What is DNA replication?
What is DNA replication?
The process of making a copy of DNA. The double helix unzips and each strand is used as a template to build a new strand.

Study Notes
Chromosomes
- 46 chromosomes in each cell (23 pairs)
- DNA coils for smaller space
- DNA is an organism's genetic material
- Contains growth, reproduction, and self-maintenance information
DNA Shape
- Double helix
- Nucleotides in the middle (like teeth of a zipper)
- Adenine pairs with Thymine
- Guanine pairs with Cytosine
DNA Replication
- Makes copies of DNA
- DNA strands unzip
- Nucleotide bases are copied
- Excess DNA is "junk DNA"
Chromosomes Hold
- DNA
- Information for making proteins
RNA
- Single-stranded
- Gets information from DNA to make proteins
- Transcription: RNA copies information from DNA
- Translation: RNA uses information to make proteins
