How big is the Drosophila genome?
∼180 Mb
The drosophila genome was given as ‘∼180 Mb in size, a third of which is centric heterochromatin’ (Adams et al., 2000).
How is a housefly adapted to its environment?
Houseflies are well adapted for their lifestyle. They fly around looking for things on which to feed and lay eggs. Their feet are made for just that purpose. They have claws for grabbing and hairs that grip smooth, wet areas with surface tension.
What are the diseases spread by house fly?
The common housefly can transmit the pathogens that cause shigellosis, typhoid fever, E. coli, and cholera. The disease-causing agents can either be transmitted by the body hairs or by the tarsi which are transmitted to food or surfaces when the fly lands.
How many genes does a fly have?
Basic Biology. There are many salient features of the fly that make it such an attractive model to study. As mentioned previously, the fly genome has been completely sequenced and annotated, and encodes for a little more than 14,000 genes on four chromosomes, only three of which carry the bulk of the genome.
How big is a genome?
A real human genome is 6.4 billion letters (base pairs) long.
How many genes are in Drosophila genome?
melanogaster sequenced genome of 139.5 million base pairs has been annotated and contains around 15,682 genes according to Ensemble release 73. More than 60% of the genome appears to be functional non-protein-coding DNA involved in gene expression control.
What is the genus of housefly?
Musca
Housefly/Genus
Are flies Dirty?
Flies are dirty. Flies don’t exactly hang out in the cleanest environments, unless you count excrement, garbage, and carcasses as clean environments. And whenever and wherever flies land and crawl, bacteria in that location can stick to their bodies, especially their legs and wings.
Is TB spread by flies?
Often they settle in dusty, dark areas. When this dust gets swirled up (by sweeping, wind, or when children play on the ground), the TB bacilli then fly through the air and may be inhaled. When they are inhaled, they travel into the lungs of the person.
How much bigger are we than flies?
The human, worm, and fly genomes are all composed of the same building blocks (i.e. nucleotides) but differ greatly in size. The human genome, for instance, is more than 10 times larger than those of the worm and fly. However, the three have comparable numbers of functioning genes that code for proteins.
