The episome in an Hfr strain is inserted near the trp (tryptophan operon) locus. This Hfr strain is grown with an F- Trp- strain

. From this mating, we isolate an F+ Trp+ strain that can readily impart the Trp+ phenotype to F- Trp- strains, but no other traits are ever transferred. (When the original Hfr strain is mated with F? strains, traits other than Trp+ can be transferred, although at lower frequency than Trp+.) What most likely has happened?

Answer:

It is a typical Hfr mating, as trp gene is very closed to F plasmid, the Hfr bacteria donates its trp gene along with F plasmid and then process is disturbed.

expeople1 [14]

Answer:

B. Hardness

Explanation:

Physical properties of a substance is defined as the properties which can be observed or measured without changing the composition of matter.

Physical properties include odor, appearance, color, texture, boiling point, melting point and many others.

Hardness is a physical property of a substance as it describes the  resistance of substance to deformation and can be observed by simple touch or without changing the composition of matter.

While reactivity, toxicity and flammability are chemical properties of substances that change one type of matter into another type.

Hence, the correct option is B.

After cell division (mitosis) how does the genetic code of the newly
Harrizon [31]

Answer:

Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.

Explanation:

Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:

G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.

S is the period of DNA synthesis, where cells replicate their chromosomes.

G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.

M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.
