Bacteria is a prime candidate for genetic engineering because of its ___________ and ____________?
N76 [4]

The given blanks can be filled with the ability to take up foreign DNA and express proteins faster.  

The direct manipulation of the genes of an organism with the application of biotechnology is known as genetic engineering. It is an array of technologies that are utilized to modify the genetic make-up of an organism, involving the transfer of genes across and within the boundaries of the species to generate novel or bettered organisms.  

In genetic engineering, bacteria play a key role, as it is an essential tool for natural scientists. The genes and other genetic information from a broad array of species can be administered into bacteria for modification and storage, thus producing genetically modified bacteria in the procedure.  

The bacteria possess the tendency to take up foreign DNA and expresses the desired proteins at a faster rate.

denpristay [2]
Established on the data, sickle cell hemoglobin displays altered primary structure and altered quaternary structure; the secondary and tertiary structures may or may not be altered. The sickle cell disease is a cluster of disorders that disturbs hemoglobin, the molecule in red blood cells that transports oxygen to cells all over the body. A person with this disorder have uncharacteristic hemoglobin molecules named hemoglobin S which can interfere with red blood cells into a sickle or crescent shape.

In a dihybrid cross of two heterozygous individuals, you expect a 9:3:3:1 phenotypic ratio in the offspring, but observe a ratio
almond37 [142]

Answer:

e. Epistatic interaction of the two genes

Explanation:

The 9:7 ratio is typical of the Duplicate Recessive Epistasis.

The expected phenotypic ratiio of the offsrping of a dihybrid cross is:

9 A_B_

3 A_bb

3 aaB_

1 aabb

In the Duplicate Recessive Epistasis, the A_bb, aaB_ and aabb individuals all have the same phenotype, making for the ratio 9:7. What those three genotypes have in common is that in all of them at least one of the two genes  is homozygous recessive (either <em>aa</em> or <em>bb</em>).

This usually happens one the products of genes A and B are enzymes of the same metabolic pathway.

Whenever both A and B are present, the pathway can produce the final product and a certain phenotype. However, if any of the dominant alleles is missing, the enzyme is not produced and therefore the final product of pathway is not produced, giving the other phenotype.

Phenylketonuria (PKU) is a genetic disease caused by mutation of the PAH gene, which normally produces the enzyme phenylalanine
Serga [27]

Answer:

The correct answer is - Pleiotropy.

Explanation:

Pleiotropy is the number of disorders where multiple, and unrelated organ systems are affected in the body of an individual. Phenylketonuria (PKU) is the most cited example of pleiotropy in humans.

It is an inherited disorder that is caused by a deficiency of the enzyme phenylalanine hydroxylase due to mutation in the PAH gene, This enzyme is necessary to convert the essential amino acid phenylalanine to tyrosine. By this disorder, multiple organ systems are affected such as severe skin discolorations and foul odor, and other intellectual disabilities and behavioral problems.
