Explanation:
The cell must be lysed (broken open) to release the nucleus. the nucleus (if present) must also be open to release the DNA. at that point the DNA must be protected from enzymes that will degrade it, causing shearing. [[ once the DNA is released, it must then be precipitated in alcohol...]
Answer: xylem and the outside, which differentiate into phloem
Explanation:
The right answer is The lac operon would be transcribed constitutively.
An operator is a nucleic acid segment to which a regulatory protein that modulates downstream gene expression is bound. it can either stimulate or inhibit the production of the gene product thus controlled.
If the operator is absent, there will be no more regulation of the operon, so the transcription of the operon will not be regulated, and the synthesis will be continuous and constitutive.
The process of development of adults from the unfertilized egg is known as parthenogenesis. Parthenogenesis occurs in insects such as bees, wasps and bumble bees. Normally, males are produced in these insects. The individuals develop from unfertilized eggs and contain the single (haploid) set of chromosome.
