Answer:
Explanation:
we have three strains.
the first is the wild type which has tryptophan mRNA which gets degraded rapidly and tryptophan synthase which is stable. therefore, in the presence of tryptophan, no new mRNA is formed and whatever tryptophan synthase was present would be diluted out as cells continue to divide.
Strain A has stable mRNA and stable tryptophan synthase. so since the mRNA is present, new enzyme will continue to form from it. However, since no new mRNA is formed, the enzyme activity will get diluted as cells divide, but at a much slower rate than the wild type.
in Strain B , synthase is rapidly degraded and no new mRNA is formed. so the tryptophan synthase activity would decrease drastically.
Answer:
The correct order would be - V, II, IV, I, III
Explanation:
Mitosis is one of the two types of cell division that occurs in an organism however they both take place in different types of cells. Mitosis is the process in which the genetic material or specifically chromosomes divide into two nuclei that are genetically identical to the parent cell. They also have a similar number of chromosomes.
Mitosis division is completed in the four stages followed by cytokinesis in order which are prophase, metaphase, anaphase, telophase, and division of cell or cytokinesis.
Thus, the correct answer is - V, II, IV, I, III.
Answer:
true
Explanation:
Each chromosome represents a single gene. Each chromosome usually contains multiple genes. All members of each species have the same number of chromosomes.
Answer:
Cell division is the process in which one cell, called the parent cell, divides to form two new cells, referred to as daughter cells. How this happens depends on whether the cell is prokaryotic or eukaryotic. Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler.
