How does crossing over add to the genetic diversity of sexually reproducing organisms?

<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>

kykrilka [37]

The antibiotic penicillin is isolated from <u><em>Penicillium notatum</em></u> fungi

Penicillin was first discovered in 1928 and was used at St. Mary's Hospital, London, by Alexander Fleming to heal wounds due to its antibacterial properties.

Explanation:

Fungi and bacteria usually produce antibiotics (as secondary metabolites) for defense mechanism. They do so to limit competition for resources with other neighboring fungi or bacteria in their environment.  This is why when a fungus or bacteria establishes itself in an environment, you hardly see other fungi or bacteria types growing in their vicinity.

Select the correct answer.
GrogVix [38]

Answer:

D.  A mutation causing uncontrolled cell division

Explanation:

Cell division is controlled by various mechanisms. Any mutations in the genes regulating the cell division lead to uncontrolled cell division. Loss of control over the process of cell division leads to the formation of tumors.  

These tumors may cause cancer if they are transformed into malignant tumors. Hence, a mutation that causes loss of control over cell division is harmful.
