(HGT)‚ also known as lateral gene transfer (LGT)‚ “is the movement of genetic material between unicellular and/or multicellular organisms‚” (Wikipedia‚ 2017‚ p.1). It is the primary mechanism for the spread of antibiotic resistance in bacteria. Question 4: discuss the danger that antibiotic resistance poses in today’s society‚ consider how man has contributed to this and suggest any strategies that you think may be able to halt it or prevent its expansion Antibiotic resistance occurs when an antibiotic

Their scientific name is Drosophila melanogaster‚ and to scientists‚ they have been a key to understand many principles of heredity including sex linked inheritance‚ epistasis‚ multiple alleles‚ and gene mapping.

the DNA form in a nucleus when a cell isn’t undergoing mitosis (ie when a cell is in interphase)? The term for the DNA form in a nucleus when a cell isn’t undergoing mitosis is known as chromatin. 4. Why is mitosis important for multicellular organisms? Mitosis is important for multicellular organisms for many reasons. For an example‚ one reason is that wounds and cuts can be healed and repaired by adding new cells in the cell division

Pollination is the transfer of pollen from the male reproductive organ (stamen) to the female reproductive organ (pistil) of the same or of another flower. 4. Which of the flowers you observed today will have the highest chance of being pollinated? Explain your choice. Of the observed flowers today‚ the one with the highest chance of being pollinated would be the sunflower. The sunflower had the brightest

If two fragments of DNA are cut by the same restriction enzyme‚ the sticky ends can join together‚ forming a recombinant DNA strand. 4. Cut plasmid and eukaryotic DNA with the same restriction enzyme… Mix fragments and allow them to match… Ligate… Transform into bacteria… Identify desired clone. 5. a.)
