Two important steps involved in genetic engineering are cutting the desired gene from its genome, then cutting the vector genome and pasting the gene into it.How is this carried out?

Select one of the options below as your answer:
A.Using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector
B.Using two different restriction enzymes for cutting the desired gene and the vector and polymerase for pasting the gene into the vector
C. Using the same ligase for cutting the desired gene and the vector and a restriction

Answers

Answer 1

Answer:

Answer;

A. Using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector.

In genetic engineering the cutting of the desired gene from its genome, then cutting the vector genome and pasting the gene into it is carried out using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector.

Explanation;

Genetic engineering involves adding a new DNA to an organisms with a goal of adding one or more new traits that are not already found in that organism.

It involves ; the isolation of DNA fragments from the donor organism; the insertion of an isolated donor DNA fragment into a vector genome and the growth of recombinant vector in an appropriate host.

Answer 2

Answer: Genetic engineering is modifying the characteristics of organism by changing its genetic material.
The main principle of genetic engineering is :

A.Using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector, is the correct answer.

CANT GET WRONG , ITS LIKE A WORK BANK BUT DONT KNOW WHAT ITS CALLED.In any family, the children may or may not look like their parents. They may or may not look like their siblings. That's because each one of us inherit half of our chromosomes from our mother and half from our father. What assortment of we get varies from child to child. Our chromosomes contain many genes, and each gene codes for a specific trait. The traits people see, like eye color hair color, or height, also depend on whether the gene is dominant or recessive. In this family, brown hair is dominant over red hair. It is very possible that these two parents could only have children with brown hair! It is also possible that their children all have red hair! Why? First, to inherit a recessive trait like red hair, you must have two genes for red hair color. Because one parent, the mother, has red hair we know the mother must have two genes for red hair. The father has brown hair. We know he must have at least one gene for brown hair but he also has one gene for red hair. What two genes will their children have? It's a matter of probability. Each child has a 100% chance of inheriting the red hair gene from their mother and a 50% chance of inheriting the red hair gene from dad. That means, all the children will have at least one gene for red hair! 1.Where do our chromosomes come from? (Twelve word phrase) 2.What codes for each specific trait?

Which one of the following interspecies relationships has a negative effect on both species?

Sickle-cell anemia is a genetically inherited disease. Homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become ill and may die. Individuals homozygous for the sickle-cell trait (ss) have sickled red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the hemoglobin disorder. However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause death. In addition, the heterozygotes tend to survive better than either of the homozygous conditions as they are resistant to malaria. If 16% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria?

Answers

Answer:

Explanation:

it depends on the total percentage of the population. that way we can pick out the percentage of the heterozygous

Final answer:

The percentage of the population that will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria is 84%.

Explanation:

To calculate the percentage of the population that will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria, we need to find the frequency of the ss genotype first. Given that 16% of the population is born with a severe form of sickle-cell anemia (ss), the frequency of the ss genotype is 0.16.

Since we are dealing with a single gene with two alleles, the sum of the frequencies of all possible genotypes should equal 1. So, to find the frequency of the Ss genotype, we can subtract the frequency of the ss genotype from 1.

Frequency of Ss = 1 - Frequency of ss = 1 - 0.16 = 0.84.

Finally, to get the percentage, we can multiply the frequency by 100.

Percentage of the population that will be heterozygous (Ss) = Frequency of Ss x 100 = 0.84 x 100 = 84%.

Smog damages everything but plants.
a. True
b. False

Answers

The answer is b. False.

Smog is named for the mixture of smoke and fog. It is an air pollutant. It is able to affect human health and environment, as well. Smog affects plant by inhibiting photosynthesis which leads to reduced growth, reproduction, and survival of the plants. It can make them more susceptible to disease or to cause drying out.

Which biome is characterized by low annual rainfall, less than 26 centimeters (about 10-11 inches) per year? A) desert B) tundra C) grassland D) tropical rain forest

Answers

The correct answer is option A

The biome that is characterized by low annual rainfall is the desert biome. It receives less than 26 centimeters of rainfall per year.

This biome has very high temperature and it is very dry.

The animals and plant species living their has special adaptation to strive in such kind of environment.

Final answer:

The desert biome is characterized by low annual rainfall.

Explanation:

The desert biome is indeed characterized by its arid and dry conditions, primarily due to low annual rainfall. Deserts typically receive less than 250 millimeters (10 inches) of precipitation each year. This scarcity of water, combined with high temperatures and often intense sunlight, results in harsh and challenging environmental conditions.

Deserts can be found on every continent and occupy about one-fifth of Earth's land surface. Despite their extreme climate, deserts are home to unique and specially adapted plant and animal species, which have evolved various strategies to survive in this water-scarce environment, such as water conservation, temperature tolerance, and nocturnal activity.

Complete the following sentence.In contrast to a three-month-old baby, a four-month-old baby is usually strong enough to hold up its
independently.

Answers

In contrast to a three-month-old baby, a four-month-old baby is usually strong enough to hold up its head independently.

A baby typically achieves an important developmental milestone around four months of age: developing enough neck and upper body strength to support their head on their own. This achievement reflects improved motor abilities and control over the neck muscles. When a baby can hold their head up on their own, it makes it easier for them to explore their surroundings and develop their cognitive and sensory abilities.

By offering supervised tummy time and moderate neck exercises, parents and other caregivers can support this developmental milestone. Your baby will eventually gain more control over his head movements as his neck muscles continue to strengthen, paving the way for additional physical and cognitive development.
