what structure does DNA have?
Double Helix structure
1 of 10
What 4 basis are DNA strands made of? And what goes with what?
4=A,T,C,G order=A with T and C with G
2 of 10
What is the order of a bases or a gene?
It is the genetic code for the production of protein
3 of 10
Explain how the order of a bases in a gene is the code for building up amino acids in the correct to make a particular protein?
This code determines the type of amino acids and the order in which they are joined together to make a specific protein. The sequence of amino acids in a protein determines its structure and function.
4 of 10
where are genetic codes and proteins found in plants and animals?
Genetic code/In the the nucleus of both P&A. Protein/In the cell cytoplasm in both P&A.
5 of 10
How does the genetic code of the gene from the nucleus get to the cytoplasm
Genes do not leave the nucleus but a copy of the gene (messenger RNA) is produced to carry the genetic code to the cytoplasm.
6 of 10
All body cells in an organism contain the same genes, many genes in a particular cell are not active.Explain why.
Many genes in a particular cell are switched off because the cell only produces the specific proteins it needs.
7 of 10
In specialised cells only the genes needed for the cell can be active.Explain why.
Only the genes needed to make a particular type of cell work are switched on. So muscle cells only have the genes needed to make muscle cell proteins switched on. All the other genes, such as those needed to make blood cell proteins and nerve cell pr
8 of 10
Why can any gene be active in an unspecialised cell?
so that during development it can produce any type of specialised cell.
9 of 10
What do adult stem cells and embryonic stem cells both have the potential to do?
They both have the potential to produce cells needed to replace damaged tissues.
