Your Answer is here... Qualitative and quantitative differences in proteins expressed in the middle silkglands of male and female silkworm larvae that differ in silk colour were investigated by high resolution two-dimensional polyacrylamide gel electrophoresis (2-D PAGE), followed by computer-assisted image analysis. About 1000 protein spots were resolved in both the sexes and most of the proteins ranged from 15 to 70 kDa and pH 4-8. Some proteins displayed higher expression in yellow cocoon, while two proteins were only expressed in female silkworm silkgland tissue through comparison and analysis using the 2-D software. These proteins especially existed in female silkworm middle silkgland tissue of yellow cocoon. Furthermore, these proteins might be involved in the expression of cocoon colour phenotype. Regards, M.

What is the difference between the pink silkworm cocoon or the white cocoon?

floss
How will you know if your silkworm cocoon has hatched?
There is a hole.
What is width of silkworm's cocoon?
1 cm
What happens to a silkworm after it produces silk and how have traditional silk farming methods led to the deaths of millions of silkworms?
The silkworm in a cocoon is thrown into boiling water to kill the silkworm. The silk is then untangled and processed into a stronger silk thread. If the silkworm is allowed to mature in the cocoon, it will make a hole (damaging the silk) as it emerges from the cocoon.
When do silkworms stop spinning their cocoon?
A silkworm will stop spinning ts cocoon once it has wrapped itself completely in the cocoon.
When does a silkworm stop spinning its cocoon?
It takes 25 to 28 days to fully spin its cocoon
How can the silkworm come out of the silk?
A silkworm comes out of the silk cocoon as a moth, if its life is allowed to complete a full cycle.
What is the time taken by a silkworm to spin a cocoon?
about 3 or 4 days
Is silk a compound?
