What situation best represents how DNA sequencing, PCR, and gene probes might be used together? Multiple Choice Scientists might
Ivahew [28]

Answer:

Scientists might replicate a strand of DNA using PCR before sequencing it. Once the sequence is known, they can produce a corresponding gene probe

Explanation:

PCR refers to the polymerase chain reaction that amplifies the small sample of DNA into multiple copies in three steps. These steps are denaturation of sample DNA to produce single-stranded template strand, binding of primer to the template and elongation. The multiple copies of the sample DNA are then used to decipher its sequence using various sequencing methods.

Once the sequence of the sample DNA is known, the short, single-stranded DNA molecules that are complementary to the specific sequence of DNA are formed. These single-stranded DNA molecules are called DNA probe and are used to detect the specific nucleotide sequence in some other sample DNA.

When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling
guapka [62]

Answer:

C) polarity

Explanation:

The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.

  • In water molecules hydrogen bonds provides a special dipole - dipole attraction.
  • Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
  • This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
  • This makes the molecule of water polar.
  • By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.

This property of water is polarity of water.

After a period of rapid growth (log phase), bacterial growth rates will slow and enter the stationary phase. The number of viabl
Stells [14]

Answer:

A. The number of cells that are dying is balanced by the number of new cells that are being formed.

C. Harmful waste products may be accumulating.

D. The cells are likely running out of nutrients.

Explanation:

During the stationary phase, the number of viable cells remains constant. This may be due to a balance between cell division and cell death wherein the total number of newly formed cells and the cells undergoing death are equal.

Nutrient limitation is one of the several factors that make the microbial cells to enter the stationary phase. Depletion of nutrients slows down the population growth.

Accumulation of toxic waste products as it occurs during the growth of anaerobic bacteria also adversely affects the population growth.

For example, the accumulation of lactic acid and other organic acids (by-products of anaerobic respiration) inhibits the growth of the population by making the medium acidic.
