Which of the following statements best describes the behavior of DNA during electrophoresis?
Longer DNA fragments migrate farther than shorter fragments
Migration distance is inversely proportional to the fragment size,
ОО
Uncut DNA migrates farther than DNA cut with restriction enzymes
O Positively charged DNA migrates more rapidly than negatively charged DNA.

Answers

Answer 1

Answer:

Migration distance is inversely proportional to the fragment size,

Explanation:

Gel electrophoresis is a technique used in molecular biology that uses electricity to separate biological molecules based on size (DNA) or charge (proteins). For the DNA molecule, different sizes are separated from one another based on how fast they can migrate through the gel matrix.

In this technique, small fragments or sizes of DNA migrates farther than long sizes of DNA due to low friction in the matrix. In other words, the smaller the size of the DNA fragment, the farther the migration distance and vice versa. This shows that an INVERSE RELATIONSHIP exists between the migration distance and the fragment size in the electrophoresis procedure.

What other factors did you modify for BEE? Why do you think you need to consider these factors with caloric intake?

Answers

Answer:

The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

If you count 60 colonies after generating a dilution factor of 10^-8 and plating 100 microliters, what is the starting concentration?

Answers

Answer:

CFU / ml = 600 x 10⁻⁸

Explanation:

Given:

Number of colonies = 60

Dilution factor = 10⁻⁸

Volume plated = 100 micro-liters = 0/1 ml

Find:

Starting concentration

Computation:

CFU / ml = [Number of colonies x Dilution factor] / Volume plated

CFU / ml = [60 x 10⁻⁸] / 0.1

CFU / ml = 600 x 10⁻⁸

Stars form from what celestial objects ?

Answers

  Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example, a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. Stars begin their lives as clouds of dust and gas called nebulae. The gravity of a passing star or the shock wave from a nearby supernova may cause the nebula to contract. Matter in the gas cloud will begin to coalesce into a dense region called a protostar.

which element would you expect to be more unstable/reactive, neon or calcium? why?

Answers

Answer:

Calcium

Explanation:

Between Neon and Calcium, neon will be more stable compared to the calcium.

Neon belongs to the group of elements on the periodic table called the noble gases. These are the most stable elements and they do not react with other elements.

Calcium on the other hand is reactive It requires a loss of two electrons to attain stability. Therefore, it is a more reactive element.

The answer is D)Translate the sequence in the other five reading frames. Gene localization by sequencing analysis. Since genes are not just a random collection of nucleotides

How may the genes be located in a DNA sequence?

Gene localization by sequencing analysis. Since genes are not just a random collection of nucleotides but instead contain recognizable characteristics, sequence inspection can be used to find them.

These characteristics define whether a sequence is a gene or not, and non-coding DNA does not have them.

Enter the Gene Name in the text box after choosing the Gene database from the Search pull-down menu on the NCBI home page and clicking Go. For guidance in searching Gene, see Gene Help. In the results, look for the Gene record you want, and then click the symbol to access it.

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive trait that causes muscular weakness, deterioration of muscle tissue, and loss of coordination. The allele for DMD is represented by Xd and the normal allele is represented by XD . Neither parent has DMD, but both of their sons express the trait. What are the genotypes of the parents?

Answers

Answer:

The correct answer is - XDXd and XD Y

Explanation:

Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-

in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.

So the correct genotype would be

mother: XDXd ( a carrier woman)

father : XDY (normal man)

Answers

Answer:

in a predictable pattern!!

Development typically occurs in a predictable pattern; however, the OTA  understands the influence of dynamic systems, including internal and external variables, on development.

Developmental patterns often follow a general sequence and progression across individuals, encompassing milestones in physical, cognitive, social, and emotional domains. This predictable pattern provides a framework for understanding typical development and helps identify potential delays or challenges in various age groups.

Internal variables refer to the individual's genetic makeup, temperament, and personal characteristics, which contribute to the uniqueness of their development. Every person has their own pace and style of progressing through developmental stages, and the OTA considers these individual differences in tailoring interventions and support.
