Show
Diagram showing how the CRISPR-Cas9 editing tool works. How was it developed?
What other techniques are there for altering genes?
What are the applications and implications?
A sperm and egg cell. Carrying out gene editing in germline cells is currently illegal in the UK. What’s the future of CRISPR-Cas9?
Better targeting of CRISPR-Cas9
This page was last updated on 2022-02-08 What is the sequence of events in gene expression?Thus, during expression of a protein-coding gene, information flows from DNA → RNA → protein. This directional flow of information is known as the central dogma of molecular biology.
Is a complex of the cell's DNA and proteins?Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.
What is the sequence from DNA to trait?Gene. A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism.
What is the pathway of genetic information in the cell?The flow of genetic information in cells is therefore from DNA to RNA to protein (Figure 6-2). All cells, from bacteria to humans, express their genetic information in this way—a principle so fundamental that it is termed the central dogma of molecular biology.
