You are given two solutions containing different purified DNAs. One is from the bacterium P. aeruginosa and has a G + C composition of 68%, whereas the other is from a mammal and has G + C composition of 42%. You measure the UV absorbance of each solution as a function of increasing the temperature. Which solution will yield the higher Tm value and why?

Answers

Answer 1

Answer:

Answer:

The solution of P. aeruginosa will yield higher Tm value.

Explanation:

The solution of P.aeruginosa contain 68% G+C composition as a result the DNA of P.aeruginosa is more stable than the DNA of mammal contain only 42% G+C composition.G+C composition is most stable because guanine is linked to cytosine by 3 hydrogen bonds whereas adenine linked to thymine by 2 hydrogen bonds.

As P.aeruginosa DNA is more stable than mammalian DNA,as a result the DNA solution of P.aeruginosa will yield high Tm(melting temperature) value than that of mammalian DNA.

The process of meiosis is illustrated here. The outcome of meiosis is very important in the sexual reproduction and life cycle ofdiploid organisms. Evaluate these statements and determine which ones accurately describe the outcome of meiosis. You may select

A)
Meiosis produces genetically diverse cells.
B)
Meiosis increases genetic variation in the offspring.
C)
Meiosis produces haploid cells from a diploid parent cell
D)
Meiosis increases the genetic content in the daughter cells.
E)
Meiosis maintains the number of chromosomes originally present in the
parent cell.

Answers

Final answer:

The accurate statements are: Meiosis produces genetically diverse cells, Meiosis increases genetic variation in the offspring, and Meiosis produces haploid cells from diploid parent cell. The inaccurate statements are: Meiosis increases genetic content in daughter cells, and Meiosis maintains original number of chromosomes in parent cell.

Explanation:

The following statements accurately describe the outcome of meiosis:

Meiosis produces genetically diverse cells. This is true. During meiosis, the genetic material from two parent cells is combined in unique ways, resulting in genetically diverse offspring.
Meiosis increases genetic variation in the offspring. This statement is also true due to the crossing over and independent assortment processes during meiosis I, which create new combinations of genes in the gametes.
Meiosis produces haploid cells from a diploid parent cell. This is accurate. The parent cell has two sets of chromosomes (diploid), while the resulting daughter cells each have a single set (haploid) due to the reduction division in meiosis.

These statements inaccurately describe meiosis:

Meiosis increases the genetic content in the daughter cells. This is false. Meiosis actually reduces the genetic content by halving the number of chromosomes.
Meiosis maintains the number of chromosomes originally present in the parent cell. This is also false. The purpose of meiosis is to reduce the chromosome number by half in the offspring to maintain a consistent chromosome number within the species across generations.

Answer:

A) Meiosis produces genetically diverse cells.

B) Meiosis increases genetic variation in the offspring.

C) Meiosis produces haploid cells from a diploid parent cell

Explanation:

Through crossing over, meiosis produces genetically diverse cells causing more genetic variation of offspring. The Daughter cells in meiosis are formed from a diploid cell that has all 46 chromosomes, however the daughter cells are haploids as they need to join with the other gamete to have a full set of chromosomes.

How long does nuclear waste need to be safely stored until it’s no longer hazardous

Answers

Nuclear waste:

Atomic waste is one of the most troublesome sorts of waste to oversee on the grounds that it is profoundly dangerous. As indicated by the U.S. Ecological Protection Agency (EPA), atomic waste is arranged into six general classes.

[1-2] These incorporate (1) spent atomic fuel from atomic reactors, (2) uranium factory tailings from mining and processing of uranium mineral, (3) significant level waste from spent atomic fuel reprocessing, (4) low-level waste, (5) transuranic waste from guard projects, and (6) normally happening and quickening agent created radioactive materials.

The well-being concerns and security issues related with atomic waste present significant limitations on the far reaching utilization of atomic vitality. Because of its b and exceptionally perilous properties, atomic waste is required to be deliberately put away or reprocessed. The putting away and reprocessing are additionally convoluted by the long half existence of the radioactive materials in the atomic waste.

For instance, a portion of the segments can remain half of their hazardous levels even one million years after the fact after generation.
