<u> Bacterial growth curve-</u>

The phase in the bacterial growth curve which is defined by  zero net growth due to a lack of nutrients and excessive waste products being present is the death phase of the growth curve.

<u>Phases of the bacterial growth curve-</u>

The bacterial growth curve is a curve that depicts the number of viable live cells in a bacterial culture over a span of time. This growth curve has four very distinct phases, which are- lag phase, log phase, stationary phase, death phase.

  • Lag phase- The first phase which is the period of metabolic growth rather than division of cells.
  • Log phase- The second phase where the cells are dividing and increasing in numbers.
  • Stationary phase- The third phase where the bacterial cells reach a stagnant period and stop dividing due to the lack of nutrients.
  • Death phase- The last phase where there is no metabolic growth or cellular division. The culture is filled with metabolic wastes from the lysis of cells.

During meiosis i, assuming no crossing over, what chromatid combination(s) will be present at the completion of prophase i?
arsen [322]

Answer

         Crossing over is the phenomenon in which exchange of chromtids occur between non sister chromatids  and result into recombinant chromatids, which is an important tool for evolution and bring about genetic changes in offsprings as compare to their parents.

No crossing over

                If no crossing over occurs, it means no exchange of chromatids between non sister chromatids of homologous chromosomes, then no recombinant chromatids will be formed.

Result

        At the end of meiosis II, when four haploid cells are formed, all these cell will contain similar chromosomes as present in parent. Thus chromosomes are non recombinant because of no crossing over.
