- Molecules of Life (B3)
- When cells are looked at under high magnification, you can see small structures of cytoplasm
- In the nucleus the cytoplasm have structures called mitochondria
- In the mitochondria respiration happens, which provides energy for life processess
- In the nucleus there are chromosomes which contain the code
- In the mitochondria respiration happens, which provides energy for life processess
- The number of mitochondria in the cytoplasm of a cell depends on the activity of the cell
- This is because respiration occurs in the mitochondria
- In the nucleus the cytoplasm have structures called mitochondria
- The chromosomes in the nucleus are made of DNA
- DNA is made of two strands coiled to form a double helix
- DNA cant leave the nucleus
- Proteins are made in the cytoplasm
- A copy of the gene need to be made so it can leave the nucleus
- Each strands contains a chemical called bases
- Four different bases, with cross links between the strands by pairs of bases
- DNA cant leave the nucleus
- DNA contains the genetic code
- The information is in the form of genes
- Genes control the activity of the cell and the organisms by coding for proteins
- The proteins that a cell produces are needed for growth and repair
- Genes control the activity of the cell and the organisms by coding for proteins
- The information is in the form of genes
- Each gene: is a section of a chromosome made of DNA - Codes for a particular protein
- Each gene contains a different sequence of bases
- DNA is made of two strands coiled to form a double helix
- When cells are looked at under high magnification, you can see small structures of cytoplasm
