HideShow resource information
The cell wall on a bacteria is more flexible. Some Bacteria have flagella on the outside, this is to propel them along
DNA FACTS-The Chromosomes in the nuceli of your cell contain your genetic information
1 of 7
One gene contains the instructions for one protein, often several genes work to together to generate a characteristic
DNA is made up of two strands of known as a double helix, they are linked together at at intervals called bases,the bases pair up the same because of the matching shapes of the molecules
2 of 7
Scientist can remove a gene from one organism and insert it into the DNA of another organism. this is known as genetically modified organisms
If a cell has two copies of Chromosome this makes them a diploid cell. Huma ndiploid cells have 23 chromosomes
3 of 7
MItosis can produce new, complete individuals in a process caled asecual reproduction
Meiosis is needed to prodece a haploid gametes. also Meiosis starts with DNA replication
4 of 7
Clones are individuals which are genetically identical. this is an example of asexual reproduction
the downside to cloning is that often the animals to clone get older much more quickly
5 of 7
When Stem cells divide, it can be used to produce other stem cells or differentiate. one a cell has differenciated it can't turn back
Embryonic stem cells can turn into any type of human cell.
6 of 7
The order of bases on a DNA strand forms the genetic coad, there of four bases 1:Adenine; Cytosine, Guanine, Thymine
There are 20 different amino acids
