CIE A Level Biology复习笔记19.2.3 Gene Therapy
Gene Therapy Gene therapy involves using various mechanisms to alter a person's genetic material to treat, or cure, diseases As scientists gain a better understanding of the human genome and theref...
CIE A Level Biology复习笔记19.2.2 Genetic Screening
Genetic Screening In certain circumstances (eg. in the pregnancy in an older woman, or pregnancy where there is a family history of a genetic disease) may require individuals to determine if they h...
CIE A Level Biology复习笔记19.2.1 Recombinant Human Proteins
Recombinant Human Proteins DNA that has been altered by introducing nucleotides from another source is called recombinant DNA (rDNA) If the organism contains nucleotides from a different species it...
CIE A Level Biology复习笔记19.1.11 Bioinformatics
Bioinformatics The various technologies (eg. microarrays and gene sequencing) being used today to analyse genes and proteins generate enormous quantities of data The data being collected ranges fro...
CIE A Level Biology复习笔记19.1.10 Microarrays
Microarrays Microarrays are laboratory tools used to detect the expression of thousands of genes at the same time and to identify the genes present in an organism’s genome Microarrays are used in m...
CIE A Level Biology复习笔记19.1.9 Gel Electrophoresis
Gel Electrophoresis Gel electrophoresis is a technique used widely in the analysis of DNA, RNA and proteins. During electrophoresis the molecules are separated according to their size / mass and th...
CIE A Level Biology复习笔记19.1.8 Polymerase Chain Reaction
Polymerase Chain Reaction (PCR) Polymerase chain reaction (PCR) is a common molecular biology technique used in most applications of gene technology, for example, DNA profiling (eg. identification ...
CIE A Level Biology复习笔记19.1.7 Gene Editing
Gene Editing Gene genome editing (or editing) allows genetic engineers to alter the DNA of organisms by inserting, deleting or replacing DNA at specific sites in the genome known to cause disease. ...
CIE A Level Biology复习笔记19.1.6 Genetic Engineering: Promoters & Marker Genes
Genetic Engineering: Promoter The promoter (an example of a length of non-coding DNA that has a specific function) is the region of DNA that determines which gene will be expressed. This is because...
