Project on transgenic animals and plants and its ethical issues

Posted by Sneha Kumari 6 years, 8 months ago

1 answers

Meghna Thapar 5 years, 8 months ago

Transgenic animals are animals that have been deliberately bred for research and that contain elements of two different species - they are creatures that blur the barrier between species.

These animals are often deliberately created with genetic defects, and these defects may well cause the animal to have a bad quality of life. A mouse has been created, for example, that has been genetically modified to develop cancer.

Ethical issues of transgenic animals

Transgenic animals raise several particular moral issues (quite apart from any damage they might do to the environment):

Are animals that combine species an unethical alteration of the natural order of the universe?
Is it unethical to modify an animal's genetic make-up for a specific purpose, without knowing in advance if there will be any side-effects that will cause suffering to the animal?
Does 'creating' animals by genetic engineering amount to treat the animals entirely as commodities?
Is it unethical to create 'diseased' animals that are very likely to suffer?
- Suffering may last for a long time in these animals as researchers want to conduct long-term investigations into the development of diseases

Religious views of transgenic animals

Against transgenic animals:

God laid down the structure of creation and any tampering with it is sinful.
Manipulating DNA is manipulating 'life itself' - and this is tampering with something that God did not intend humanity to meddle with.

In favour of transgenic animals:

As human beings have been given 'dominion' over the animals, they are entitled to tamper with them.
Palaeontology shows that the structure of creation has changed over time as some species became extinct and new ones came into being. They say that this shows that there is nothing fixed about the structure of creation.

Transgenic animals and religious food laws

Transgenic animals pose problems for religions that restrict the foods that their believers can eat, since they may produce animals that appear to be one species, but contain some elements of a forbidden species.

Complete blood count (CBC). This common blood test measures the amount of various types of blood cells in a sample of your blood. Blood cancers may be detected using this test if too many or too few of a type of blood cell or abnormal cells are found.
A bone marrow biopsy may help confirm a diagnosis of a blood cancer.

Your question is right, but Mendel proposed his " law of inheritance for living organisms " (given in NCERT book in topic 5.1) not only for plants. It means he gives his postulates also for human beings (but by without studying human beings ).

Write down the note on replication of dna

CBSE > Class 12 > Biology

1 answers

Ďãřşháñăã Yadav ? ? ? ✊ 6 years, 8 months ago

⏩DNA replication is the phenomenon in which a duplicate copy of DNA is synthesised. ⏩ In replication, two strands of the DNA helix separate and each strand acts as a template for synthesising new complementary strands. ⏩ After completion of replication, the two copies so produced will have one parental and one newly synthesised strand. This scheme of replication is called semi-conservative replication.

(1.) What is monosomic condition ? (2.) X-chromosome is also called *** chromosome. Why?

Posted by Yash Rajpoot 6 years, 8 months ago

CBSE > Class 12 > Biology

2 answers

Sia ? 6 years, 8 months ago

Monosomy is a form of aneuploidy with the presence of only one chromosome from a pair. Partial monosomy occurs when only a portion of the chromosome has one copy, while the rest has two copies.
Females have two X chromosomes in their cells, while males have both X and a Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome. This arrangement means that it is the male that determines the *** of the offspring when fertilization occurs.

Due to this change (no cell wall deposition )there is different solid mass and water is present in mature coconut seed.

ANSWER

Can you recall what centrifugal force is and think why a molecule with higher mass/ density would sediment faster ?

Posted by Anita Dogra 6 years, 8 months ago

CBSE > Class 12 > Biology

1 answers

Meghna Thapar 5 years, 7 months ago

Centrifugal force acts in case of circular motion only. It is the type of force that directs molecules away from the centre. Similarly, the same concept is applicable in the case of molecules comprising high mass or density. It is the centrifugal force that helps in faster sedimentation of higher mass molecules. Higher the mass, more gravitational force applies to it. Also mass and velocity are inversely proportional to each other. Therefore, the high mass will sediment faster by centrifugation.
