- stem cells and DNA tech
- are undifferentiated and can continually divide
- can become specialised
- totipotent
- can produce ANY TYPE OF CELL
- translate only part of their DNA resulting in cell specialisation
- =limited and only occur in embryos
- pluripotent
- can become almost any type of cell + found in embryos
- used to treat human disorders
- can be used to regrow damaged cells
- issues -can continually divide to produce tumors
- unipotent
- one type of cells
- multipotent
- limited number of cells - in the bone marrow
- Recombinant
DNA technology
- Amplification
of the DNA
fragment or
gene
- Polymerase chain
reaction (PCR) is a
way of amplifying DNA
fragments in vitro
- Requires the DNA fragment, DNA polymerase, nucleotides, primers and a thermocycler
- Polymerase chain
reaction (PCR) is a
way of amplifying DNA
fragments in vitro
- Transfer of DNA fragments between organisms
- Production of
fragments of DNA
- Convert mRNA to
cDNA by reverse
transcriptase
- Restriction enzymes
to cut DNA at specific
positions
- Gene machine to create the gene fragment
- Restriction enzymes
to cut DNA at specific
positions
- Convert mRNA to
