process in which bacterial cells take up segments of foreign DNA that become part of their genetic make-up.
One of the many restriction enzymes each of which cuts double-stranded DNA at specific short sequences of nucleotides.
A bacterial endonuclease that cuts double-stranded DNA at a location determined by a segment of guide RNA.
complementary DNA (cDNA)
double-stranded DNA synthesised using single-stranded RNA, such as mRNA, as the template.
describes a strong chemical bond formed between atoms when they share electrons.
A tool for precise and targeted genome editing that uses specific RNA sequences (gRNAs) to guide an endonuclease, Cas9, to cut DNA at the required positions.
a process by which changes to the DNA sequence of genes can be achieved; also termed gene editing.
technique for sorting through an electric field a mixture of DNA fragments (and other molecules with a net charge) on the basis of different fragment lengths.
a technique that uses brief exposure of host cells to an electric field to enable the entry of segments of foreign DNA into the cells.
process of making multiple identical copies of a specific gene or segment of DNA.
a component of the CRISPR gene-editing system.
in situ hybridisation
an inherited X-linked disorder of which there are several forms; the disease is 'severe' because the immune system is greatly weakened, and the disease is 'combined' because the disorder affects two types of white blood cells that are key components of the adaptive immune system
enzyme that catalyses the joining of two double-stranded DNA fragments.
multiple cloning site (MCS)
also known as a polylinker, an MCS is a short DNA segment within a plasmid that contains recognition sites for a number of different restriction enzymes.
origin of replication (ORI)
the segment of DNA in a plasmid at which DNA replication begins.

Which statements are true? Explain why or why not. The membrane potential arises from movements of charge that leave ion concentrations practically unaffected, causing only a very slight discrepancy in the number of positive and negative ions on the two sides of the membrane.
Design an experiment. You might have heard that drugs affect people in different ways and at different rates. How would you design an experiment to determine the rate at which a drug is delivered to different body tissues?
dna replication occurs during which phase of the cell cycle
Hybrid corn is produced that is resistant to bacterial infection and is highly productive. What might have been the phenotypes of the two parents?
