Why do calculated recombination frequencies between pairs of loci that are located far apart underestimate the true genetic dist
den301095 [7]

Answer:

B. As the distance between loci increases, some multiple crossovers go undetected such that the relationship between recombination frequency and map distance ceases to be linear.  

Explanation:

When calculating recombination frequencies, and hence, map distances, we might notice that these distances are not completely additive. They might vary. <em>For example, let us say that we have three genes, A, B, and C, in that order. </em>We calculated that the <em>distance between A and B equals 5.9</em> MU and that <em>B and C are 19.5 MU apart.</em> According to this, we might say that the <em>total distance between A and C is 25.4 MU (5.9 + 19.5). </em>However, after a<em> two-point calculation between A and C, the value equals 23.7 MU. </em>

The recombination frequency between these two genes located in the extremes and far apart underestimate the actual genetic distances between them because there might occur other crossing-overs that were not detected. This is <em>when calculating the distance between A and C, we probably will not detect the occurrence of a double recombinant between them, and hence, we might sub-estimate the real distance.</em>

The relationship between the actual map distance (number of crossing overs) and the recombination frequency between two loci, is not lineal. The farther apart are the two genes, the worse is the distance estimation.

The free energy for ATP hydrolysis in vivo is actually &gt; the standard free energy change of -30 kJ mol-1 because ________. a.
Julli [10]

Answer:

The correct answer will be option C.

Explanation:

ATP is the energy molecule which on hydrolysis provide energy to the cells for metabolic functions.

In vitro, the standard free energy of the ATP is -30.5 kJ/mol but its value varies in the cell as the concentration of ATP and its products like ADP, AMP and Pi are unequal in a cell. The Mg2+ in the cytosol has the ability to bind ATP and ADP, as well as the time of ATP hydrolysis, differs from cell to cell, thus influencing the concentration of ATP and its products.

Thus, option C is the correct answer.

ollegr [7]

Cysteine contributes to the three-dimensional structure of a protein by forming covalent bonds with an identical amino acid in another part of the protein.

<h3>What is the Cysteine Structure?</h3>
  • Covalent disulfide bonds form between the sulfhydryl (-SH) groups of cysteines in different parts of a protein are very important in determining the three-dimensional shape of the protein.
  • is a HOOC-CH-(NH2)-CH2-SH proteinogenic amino acid that is semi-essential. Cysteine's thiol side chain frequently functions as a nucleophile in enzyme processes.
  • The sign Cyz is occasionally used when a deprotonated catalytic residue is present.
  • The sign Cym can also be used to usually denote the deprotonated form.
  • The thiol is capable of being oxidized to produce the disulfide derivative cystine, which is crucial for many proteins' structural integrity. Cyx is sometimes used in this context. It carries the E identifier E920 when added to food.
  • The codons UGU and UGC encode the amino acid cysteine.
  • Cysteine and methionine, which contain sulfur, are more quickly oxidized than other amino acids.
