- DNA
- The molecule has two strands coiled together in the shape of a double helix
- Each strand is made up of lots of small units called nucleotides
- Each nucleotide contains a small molecule called a base
- Each strand is made up of lots of small units called nucleotides
- A gene is a section of DNA that contains the instructions for one particular protein
- Cells make proteins by joining amino acids together in a particular order
- The order of the bases in a gene that tells the cell in what order to put the amino acids together
- Each set of three bases codes for one amino acid
- The order of the bases in a gene that tells the cell in what order to put the amino acids together
- Cells make proteins by joining amino acids together in a particular order
- Proteins are made in the cell cytoplasm by organelles called ribosomes
- It is found in the cell nucleus and can't move out of it because it is really big
- To get information from the DNA to the ribosome, a copy of the DNA is made using a molecule called messenger RNA
- Messenger RNA is very similar to DNA but its much shorter and only a single strand
- The molecule has two strands coiled together in the shape of a double helix
