Give reasons. 1. Silkmoth is called the queen of fibers.
2. The cocoon of a silkworm is kept in an oven or in boiling water.
3. Farmers keep the silkmoth's eggs at cold places in water.
4. Honey bees are vital pollinators.

1.It produces silk which is a high quality fibre

2.to destroy the gelatinious substance inside cocoon so as to obtain silk thread

3.To avoid it from hatching

4.they carry pollen grains while roaming plant to plant and help in cross pollination

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
