What is bigger than a genome?
From smallest to largest: nucleotide, gene, chromosome, genome. … A chromosome is a long strand of DNA which is coiled up with various proteins. A chromosome contains many genes. The genome is all the DNA of a particular organism.
Is the human genome is the largest on Earth?

How big is the human genome compared to other species?
How Many Protein-Coding Genes Are in That Genome?
|Species and Common Name||Estimated Total Size of Genome (bp)*|
|Gallus gallus (chicken)||1 billion|
|Canis familiaris (domestic dog)||2.4 billion|
|Mus musculus (laboratory mouse)||2.5 billion|
|Homo sapiens (human)||2.9 billion|
How many MB is human genome?
The 2.9 billion base pairs of the haploid human genome correspond to a maximum of about 725 megabytes of data, since every base pair can be coded by 2 bits. Since individual genomes vary by less than 1% from each other, they can be losslessly compressed to roughly 4 megabytes.
What is the largest gene?
The largest known gene is the human dystrophin gene, which has 79 exons spanning at least 2,300 kilobases (kb).
Which mammal has largest genome?
In 1999, scientists discovered that a rodent in Argentina, the red vizcacha rat, Tympanoctomys barrerae, has the largest genome in mammals, at a size nearly three times larger than that of humans.
