9

Production of Insulin by Bacteria

One prominent application of changing an organism’s genotype

New cards
10

Ethical considerations

Addressing ethical and safety concerns for responsible and beneficial applications.

New cards
11

Insulin Production in Bacteria

Process of inserting the human insulin gene into bacteria to produce insulin.

New cards
12

Human insulin gene

this is a segment of DNA encoding the instructions for insulin production, precisely inserted into the bacterial genome

New cards
13

Recombinant DNA Technology

This integration of insulin production is achieved using advanced molecular biology techniques, such as what?

New cards
14

Bacterial culture

Carefully cultivated under controlled conditions. This ensures optimal growth and maximum insulin production.

New cards
15

Purification

involves precise filtration steps, chromatography techniques, and protein separation methods

New cards
16

Viruses

can be used as vectors to deliver genes of interest into cells.

New cards
17

Vectors

Using viruses or microinjection/gene guns to deliver genes into cells for genetic manipulation.

New cards
18

Microinjection

Involves directly injecting DNA into the nucleus of cells using a fine needle, while gene guns use high pressure to shoot DNA-coated particles into the cells.

New cards
19

Clustered Regularly Interspaced Short Palindromic Repeats

Meaning of CRISPR

New cards
20

CRISPR-Cas9

Cas9 nuclease enzyme

CRISPR allows for precise editing of DNA sequences by using the _____

New cards
22

gRNA

Cas9 is guided to the target gene by a small RNA molecule called

New cards
23

CRISPR technology

is utilized in various organisms, including plants, animals, and humans.

New cards
24

Gene Editing

Manipulating DNA to remove or insert specific genes with high precision.

New cards
25

Ethical Concerns

Human Genetic Engineering, Environmental Impact, Informed Consent, Safety, and Social Justice.

New cards
26

Ethical Frameworks

Utilitarianism, Deontology, Virtue Ethics.

New cards
27

Utilitarianism

Assessing the overall benefits and harms of genetic engineering to determine if the benefits outweigh the potential risks and ethical concerns.

New cards
28

Deontology

Evaluating genetic engineering practices based on moral duties and principles, such as respect for autonomy, justice, and non-maleficence.

New cards
29

Virtue Ethics

Examining the character traits and virtues that genetic engineering promotes or undermines, such as compassion, fairness, and responsibility.

New cards
30

Ethical considerations

The process of addressing ethical and safety concerns for responsible and beneficial applications.

31

Escherichia coli

Meaning of E. coli

New cards
32

E. coli

Susceptible bacterial host of insulin production

New cards
33

Animal-based insulin production

Not sustainable and cost-effective compared to insulin production in bacteria

New cards
34

Gene Therapy

Using viruses or microinjection/gene guns to deliver genes into cells for genetic manipulation.

New cards
35

Eugenics

aims to improve the genetic quality of the human population through selective breeding and controlled reproduction.

New cards
36

Genetically Modified Organisms

meaning of GMOs

New cards
37

GMOs

are living organisms whose genetic material has been altered using biotechnology techniques. They are commonly used in agriculture to enhance crop yield, improve resistance to pests or diseases, and increase nutritional value.

New cards
