If DNA is digested by endonucleases in four sites giving rise to fragments of which two are equal in length how many bands would be seen after electrophoresis?

Genomes and DNA topics include: Genome organization, eukaryotic dna features, palindromes, inverted repeats and stem and loop structures, dna fragments separation by electrophoresis, dna helical structures, dna topology, chromatin centromere and telomere. A genome is an organism's complete set of DNA instructions. It contains all the information needed for an individual to develop and function.  The genome is made up of DNA, a long two-stranded chemical polymer. Each DNA strand is made up of four different units, called nucleotides, that are linked end to end to form a long chain.  Most... Show more

A genome is an organism's complete set of DNA instructions. It contains all the information needed for an individual to develop and function. 

The genome is made up of DNA, a long two-stranded chemical polymer. Each DNA strand is made up of four different units, called nucleotides, that are linked end to end to form a long chain. 
Most genomes, including the human genome, are made of DNA (deoxyribonucleic acid). However, a few viruses have RNA (ribonucleic acid) genomes. 
In humans, the genome consists of 23 pairs of chromosomes located in the cell's nucleus, as well as a small chromosome in the cell's mitochondria. 
The study of the genome is called genomics.

The Human Genome Project was started in 1990, and reported the sequence of the human genome in 2003. In March 2022, scientists reported the first end-to-end human genome sequence.
