Suppose a plant breeder wants to isolate mutants in tomatoes that are defective in DNA repair. However, this breeder does not ha

ve the expertise or equipment to study enzymes in DNA repair systems.
Which methods would best allow the breeder to identify tomato plants that are deficient in DNA repair?
A) Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.
B) Measure the amount of post-translational processing that occurs in the putative DNA repair mutant plants. Measure the somatic mutation rates for the putative DNA repair mutant plants.
C) Expose the putative DNA repair mutant plants to a deaminating agent and select those that have a decreased mutation rate.
D) Measure the germ line spontaneous and induced mutation rates for the putative DNA repair mutant plants.

The provided question has marked options incorrectely the correct order as follows:

A) Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.

B) Measure the amount of post-translational processing that occurs in the putative DNA repair mutant plants.

C) Measure the somatic mutation rates for the putative DNA repair mutant plants.

D) Expose the putative DNA repair mutant plants to a deaminating agent and select those that have a decreased mutation rate.

E) Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Answer:

The correct answer is: A), C) and E)

Explanation:

The breeder wants to isolate the mutants in tomatoes that are defective in DNA repair, to identify such plants breeder should follow these methods as they will allow best to identifying the defective tomatoes-

Measure the somatic mutation rates for the putative DNA repair mutant plants.

Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.  This will allow the breeder to see and analyze the ability of DNA repair in tomatoes

Tasya [4]

Answer:

The chromosomes are arranged in their respective homologous  pairs. In humans, this displays 22 pairs of autosomes and 1 pair of sex chromosome.

Explanation:

Chromosomes that are similar in their size and shape and also display similar genetic traits and carry the same genetic information are paired together. These are known as homologous chromosomes. These chromosomes carry different variations of similar genes in them. In humans there are 46 chromosomes in total. These chromosomes are paired and form 23 homologous pairs. Among these 23 homologous pairs, 22 pairs are autosomes and one pair are the sex chromosomes which are either (XX or XY). The sex chromosomes determine the sex of an individual. XX chromosomes represent a female and XY chromosomes represent a male.

Give an example of how a biome is an open system from the point of view of the biosphere, atmosphere, lithosphere, and hydrosphe
Karolina [17]

Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.

<h3>What is the biome?</h3>
  • The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
  • In order to describe an open system, we say that the system must have external interactions.
  • A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
  • The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
  • A prime example is the movement of water through each of the spheres.

Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

When is the only time a black spider monkey sets foot on the ground
yawa3891 [41]

Answer:

hey have long, lanky arms and prehensile (gripping) tails that enable them to move gracefully from branch to branch and tree to tree. These nimble monkeys spend most of their time aloft, and maintain a powerful grip on branches even though they have no thumbs.

These New World primates are social and gather in groups of up to two- or three-dozen animals. At night, these groups split up into smaller sleeping parties of a half dozen or fewer. Foraging also occurs in smaller groups, and is usually most intense early in the day. Spider monkeys find food in the treetops and feast on nuts, fruits, leaves, bird eggs, and spiders. They can be noisy animals and often communicate with many calls, screeches, barks, and other sounds.
