We transformed E coli cells with a plasmid modified to contain a ‘virulence factor’ which would allow growth on media containing the antibiotic kanamycin (Kan). The plasmid confers constitutive resistance to ampicillin (Amp).
Assume you were given competent cells of known transformation efficiency (TE). Assume TE= 1x10[6] (note 10[6] means 10 to the power of 6). You want to have about 1000 colonies on the P-200 plate. How many nanograms of plasmid should you use in the transformation reaction? Select only one answer.
Answers
We need 1 nanogram of plasmid in the transformation reaction when the transformation efficiency is given for 1000 colonies on plate P - 200.
Given the value of transformation efficiency (TE) = \(1 * 10^6\)
Number of colonies on the plate P-200 = 1000
To calculate the amount of plasmid (in nanograms) required for transformation, we need to first calculate the number of cells required for transformation.
To get desired number of cells we multiply the transformation efficiency and number of colonies given such that:
number of cells = \(TE (1*10^6) * 1000 colonies = 1 * 10^9 cells\)
Since 1 nanogram of plasmid is equivalent to \(1 * 10^9\) cells, we can conclude that we need to use 1 nanogram of plasmid in the transformation reaction.

Female Drosophila with cinnabar eye (cn) and vestigial wings (vg) were mated to males with roof wings (rf). The F1 were all wild-type. When the F1 females were test crossed with homozygous for all three traits following results were obtained. Cinnabar vestigial 382; roof 401; cinnabar 3; roof, vestigial 4; cinnabar, roof, vestigial 59; wild 67; cinnabar roof 44; vestigial 40. Determine the map distance between each pair of loci. The geneticist is also aware that genes D and E assort independently. Draw a map of these genes, showing distance in map units wherever possible.
Answers
Since genes D and E are said to assort independently, we can assume that they are on different chromosomes and therefore not linked.
What is genotype?To solve this problem, we need to first determine the genotypes of the F1 females. Since all of the F1 females were wild-type, we know that they must have had at least one dominant allele for each of the three traits: wild-type eye (cn+), normal wings (vg+), and normal body (rf+).
We can represent the genotype of the F1 females as follows: cn+ vg+ rf+/cn+ vg+ rf+. When these females were test-crossed with homozygous recessive males (cn cn vg vg rf rf), we observed the following offspring:
Cinnabar vestigial (cn vg): 382
Roof (rf): 401
Cinnabar (cn): 3
Roof vestigial (rf vg): 4
Cinnabar vestigial roof (cn vg rf): 59
Wild-type (cn+ vg+ rf+): 67
Cinnabar roof (cn rf): 44
Vestigial (vg): 40
We can use these numbers to calculate the recombination frequency (RF) between each pair of loci using the formula: RF = (number of recombinant offspring / total number of offspring) x 100%.
RF between cn and vg:
Recombinant offspring = cn vg + cn + cn vg rf + cn rf = 382 + 3 + 4 + 44 = 433
Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000
RF = (433/1000) x 100% = 43.3%
RF between vg and rf:
Recombinant offspring = cn vg rf + cn+ vg+ rf+ = 59 + 67 = 126
Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000
RF = (126/1000) x 100% = 12.6%
RF between cn and rf:
Recombinant offspring = cn rf + cn+ vg+ rf+ = 44 + 67 = 111
Total offspring = 382 + 401 + 3 + 4 + 59 + 67 + 44 + 40 = 1000
RF = (111/1000) x 100% = 11.1%
Now we can use these recombination frequencies to construct a genetic map:
cn -- 43.3 mu -- vg -- 12.6 mu -- rf

Body waves. The p-wave propagates as a compression wave that moves through both solid and fluid materials. The s-wave is an undulating wave that moves the medium perpendicular to the direction of
propagation of the wave S-waves do not propagate through any medium that is liquid.
Surface waves - surface waves travel much slower compared to either p- or S waves . Surface waves called love waves and Rayleigh waves are responsible for the destructive effects that earth quacks have on the landscape and ma made structures.
Body waves travel deep into the Earth and are reflected by the core returning to the surface layers of the planet many thousands of miles away from where the actual earthquake event occurred. Scientists
have been able to use this property of seismic waves to study the internal structure of the Earth.

A only p waves caused by an earthquake transfer enough energy to reach the core of the earth and be reflected back to the surface.
B only p waves cause by an earthquake can be detected after reflection from the core of the planet.

glutamic acid—phenylalanine—threonine—lysine
Answers
According to the table that represents the genetic code, the amino acid sequence that corresponds with the mRNA sequence GAA UUU ACG AAA is glutamic acid-phenylalanine-threonine-lysine (Option D).
What is the genetic code?The genetic code is the information contained in the DNA sequence, which is sued to produce a given sequence of amino acids in a protein during translation. The triplets of nuclotides or codons in DNA are used to generate the proteins, e.g., the GAA codon is used to add glutamic acid.
The genetic code links a given sequence of amino acids during the translation in the ribosome with specific codons in the mRNA sequence, which are complementary to the DNA sequence obtained during translation since transcription and translation are cellular processes that are interrelated and dependent on each other to produce a protein.
Therefore, we can conclude that the sequence glutamic acid - phenylalanine - threonine - lysine is encoded by using the mRNA sequence GAA UUU ACG AAA (Option D).

Does the pharynx of human respiratory system have cartilage and epithelium?
Answers
Answer:
There is no cartilage but there is epithelium
Explanation:
The pharynx of the human respiratory system does not contain cartilage.
The pharynx, part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for air and food. The gorge is made up of several regions, each with its own distinctive features.
The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.
These regions also lack cartilage but are lined with stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

What are membranes like the cell membrane allows some molecules to pass through a call
Answers
Membranes, like the cell membrane, are essential parts of cells because they serve as a barrier to control how chemicals enter and exit the cell.
Membranes are essential components of cells. They form a barrier between the interior of the cell and the outside environment and regulate the passage of molecules in and out of the cell. The cell membrane is a type of membrane that allows some molecules to pass through a cell. It is a selectively permeable membrane that allows only certain substances to pass through. The structure of the cell membrane is composed of a lipid bilayer, which consists of two layers of phospholipids. These phospholipids have a hydrophilic head and a hydrophobic tail. The hydrophilic head is attracted to water and the hydrophobic tail repels water. This arrangement allows the cell membrane to form a barrier that separates the inside of the cell from the outside environment. The cell membrane also contains proteins and other molecules that allow it to regulate the passage of molecules in and out of the cell. In summary, membranes such as the cell membrane are critical components of cells and act as a barrier to regulate the passage of molecules in and out of the cell.For more questions on Membranes

Based on the data collected, it can be inferred that the time spent in each stage of the cell cycle is not approximately equal. The longest stage is Interphase, while the shortest stage is Cytokinesis. This may be due to the fact that Interphase is a stage of cell growth and DNA replication, while Cytokinesis is simply the division of the cytoplasm. Therefore, more time is needed for the growth and replication processes. The hypothesis that the time spent in each stage of the cell cycle will be approximately equal is rejected.
Questions:
The nucleus of a dividing cell appears to be more condensed and visible, while the nucleus of a non-dividing cell appears more diffuse and spread out.
