We estimate that reversion of the lac mutation is about one-tenth as likely as a null frameshift mutation in a typical gene. |
|
In addition to the lac operon, a number of other synthetic and natural genetic circuits have been analyzed for robustness and evolvability. |
|
Pigeonpea was once widely grown in China as a host for lac insects, the source of shellac. |
|
Because the lac insect is sedentary, densities on branches can become very high. |
|
The local farmers raise lac insects on the natural host trees and intercrop agricultural crops under the host trees as well. |
|
However, the wax used is derived from natural sources like food-grade shellac, which comes from the secretion of a lac bug, it is pointed out. |
|
These strains might not even use their lac gene products to metabolize lactose. |
|
A lower intensity of mutagenesis can explain all observed revertants if each mutagenized cell has multiple copies of the lac operon. |
|
The lac insect sucks the sap from small branches of the Kusumi tree, then secretes through its pores the lac resin. |
|
The traditional use of rearing lac insects on the stem of the pigeonpea plant also continues. |
|
Methods of improved control of lac parasites and of preventing the lac insect from developing as a pest on non-host species need further study. |
|
This hard resinous coating originates from the plant sap metabolized by the lac insect. |
|
Lac is a resinous substance produced by a female lac insect and found abundantly in the plain forests in India. |
|
The natural coloration of lac residue is greatly influenced by the sap consumed by the lac insect and the season of the harvest. |
|
The dry and hot valley of the Honghe River in Yunnan is the best place suitable to the growth of lac insects and the best region for high grade lac production. |
|
Other events are correlated with the stable exploration of new niches, like the acquisition of the lac operon by E. coli or pathogenicity islands by Salmonella. |
|
Insects such as houseflies, bedbugs, locusts, butterflies, honeybees, silkworms, lac insects etc. are well known to mankind, largely due to their economic importance. |
|
The lac insect is found largely on banyan and juniper trees. |
|
Also, as lac insects are cultured on host trees, promotion of lac and its culture helps in eco-system development as well as reasonably high economic returns. |
|
Reports from Thailand indicate that the lac insect became a serious pest of fruit trees, so much so that the insects had to be controlled by chemical and bio-control methods! |
|
|
Other species including the cochineal insect, the lac insect, and the ground pearls—have some commercial value. |
|
After the seed lac is melted, strained through canvas, spread, cooled, and flaked, it becomes the shellac of commerce. |
|

|
The «Jardins intérieurs du lac », Inn offers 16 welcoming and comfortable rooms as well as 5 studios with kitchenettes. |
|
The lac insect is also used in used in varnishes and polishes. |
|
In this paper, the species resources and genetic diversity of lac insects were briefly introduced, and the lac productive model was also put forward. |
|
This is achieved by a protein called the lac repressor, which is produced by the repressor gene and binds to a region of the operon called the operator. |
|
If lactose enters the cell, it binds to the lac repressor and induces a change of shape in the repressor so that it can no longer bind to the DNA at the operon. |

|
Some artisans engage in sericulture, while others manufacture lac and glasswork, handloom products, brassware, stone carvings, cane and bamboo products, various woodworks, and pottery. |
|
The public targeted by this project is linked to the area where the striped bass existed before its disappearance in the 1960s, namely from Montmagny to lac Saint-Pierre. |
|
