Answer:
The correct option is a (true).
Explanation:
Personally i have experienced that microbes living in saline condition were isolated from soil and grown them on Lauria Bertani media.
Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. ... There, the recombinant bacteria use the gene to begin producing human insulin. Scientists harvest the insulin from the bacteria.
Crossing over, or recombination is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
The answer is alleles. In addition, the phenotype of an organism is the physical look resulting from the expression of the genes present. The principle of segregation states that substitute alleles for a trait discrete from one another throughout gamete formation and keep on distinct. A diploid organism that has two alike alleles for the same trait is named homozygous for that particular trait.
Answer:
Formas: todas las bacterias se pueden clasificar en una de las tres formas básicas: esferas (cocos), bastones (bacilos) y espirales o hélices (espiroquetas). Necesidad de oxígeno: las bacterias también se clasifican en dos grupos, según si necesitan oxígeno para vivir y crecer o no les es necesario.
