ATP hydrolysis _______.
yaroslaw [1]

Answer:

The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.

Explanation:

Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.

     To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.

    As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.

The illustration below shows the steps of meiosis I. What is the step that is labeled D? metaphase I metaphase II telophase II t
WITCHER [35]

The right answer is metaphase II.

The process is performed in two nuclear and cytoplasmic divisions, called first and second meiotic division or simply meiosis I and meiosis II. Both include prophase, metaphase, anaphase, and telophase. First division prophase is long and consists of 5 stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. It is at this point that genetic recombination takes place at the level of chiasmus.

During meiosis I, the members of each homologous pair of chromosomes are paired during prophase, forming bivalents. During this phase, a protein structure, called synaptonemal complex form, allows recombination between homologous chromosomes. Subsequently, a large condensation of the bivalent chromosomes occurs and go to the metaphase plate during the first metaphase, resulting in the migration of n chromosomes to each of the poles during the first anaphase. This reduction division is responsible for maintaining the number of chromosomes characteristic of each species.

In meiosis II, as in mitosis, the sister chromatids comprising each chromosome are separated and distributed between the nuclei of the daughter cells. Between these two successive steps, there is no DNA replication. The maturation of the daughter cells will result in the gametes.

Which is a negative consequence of using DNA technology in forensics?
seropon [69]
<h3><u>Answer;</u></h3>

Having untested DNA samples

<h3><u>Explanation;</u></h3>
  • <em><u>DNA technology has a great and a wide variety of important uses, which ranges from,paternity testing, to matching the DNA samples of suspects collected at a crime scene, to matching relatives to a missing person's DNA.</u></em>
  • However, <em><u>use of DNA in forensics may have negative consequences which includes, the backlogs of forensic evidence and also present of untested DNA samples which delays the whole process.</u></em>
  • <em><u>Having untested DNA samples refers to presence of evidence collected from the crime scenes that is untested and instead it is stored in the law enforcement evidence rooms and has not been submitted to crime laboratory to be analyzed. </u></em>
