In fruit flies, one genotype for red eyes is written XRXR. The R stands for the dominant allele for red eyes. What does the X st
Reil [10]

Answer:

The correct answer is : the female chromosome

Explanation:

  • According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
  • RR is a genotype for Red eyes.
  • A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
  • In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
  • Therefore, XX must represent another trait.
  • By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
  • Given XX genotype represent a female fruitfly chromosome.

<h2><em>Hypothetical Proteins</em></h2>

Explanation:

  • The <em>segments of deoxyribonucleic acid (DNA)of Genes</em> and that contain the code for a particular protein that functions in one or more types of cells the body
  • Chromosomes are structures inside cells that contain an individual's qualities
  • <em>Qualities are contained in chromosomes, which are in the cell nucleus</em>
  • <em>'Hypothetical proteins' (HPs),</em> required to portray as useful competitors can't be disregarded
  • The HPs are proteins that are anticipated to be communicated from an <em>open reading frame (ORF),</em> however for which there is no experimental <em>evidence of translation</em>

A) explain what would happen to atp production in a mitochondrion that has "leaky membranes", which would allow protons to diffu
ratelena [41]

B) In the process of the citric cycle that occurs in the mitochondrial matrix, electrons from this chemical pathways move from one protein complex to another and are ultimately accepted by oxygen molecule in the formation a water molecule. Concomitantly, protons are transported to the intermembrane space. Accumulation of H+ ions in the mitochondrial membrane creates an electromotive force that is harnessed by ATP synthase to enable the phosphorylation of an ADP to ATP.


A)     A leaky membrane, therefore, would interfere with the accumulation of protons in the intermembrane space. This will reduce the electromotive force that is harness by the ATP synthase to produce ATP by phosphorylation of ADP. Consequently, this defective mitochondria will produce less ATPs than a healthy mitochondria.
