6. Discuss genetics of human diseases with suitable examples.

answer :

Introduction:

Genetics is a field of study that investigates the role of genes in the development of different traits and characteristics in living organisms. In the case of human diseases, genetics plays a significant role in the development of many conditions. This paper will discuss the genetics of human diseases and provide examples to illustrate the genetic causes of these disease.

Genetics plays a significant role in the development of many human diseases. Some examples of genetic diseases include:

  1. Cystic fibrosis: This is an inherited disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which leads to the accumulation of thick mucus in the lungs, pancreas, and other organs.

  2. Sickle cell anemia: This is a blood disorder caused by a mutation in the HBB gene, which codes for hemoglobin, the protein in red blood cells that carries oxygen. The mutation leads to the formation of abnormal hemoglobin, which causes the red blood cells to become sickle-shaped and unable to move easily through blood vessels.

  3. Huntington's disease: This is a progressive brain disorder caused by a mutation in the huntingtin gene. The mutation leads to the production of a toxic protein that destroys nerve cells in the brain, causing a decline in mental and physical abilities.

  4. Tay-Sachs disease: This is a rare genetic disorder caused by a deficiency in an enzyme called hexosaminidase A, which breaks down a fatty substance called ganglioside GM2. The buildup of this substance in the brain leads to progressive damage, resulting in severe neurological symptoms.

  5. Hemophilia: This is a disorder caused by a gene mutation which leads to the dysfunction of a clotting factor, it can be inherited by both dominant and recessive pattern.

It's important to note that while genetics may play a role in the development of these diseases, other factors such as lifestyle and environment can also contribute.

Conclusion:

In conclusion, genetics plays a significant role in the development of many human diseases. The examples provided in this paper illustrate how genetic mutations can lead to the dysfunction of specific proteins, resulting in the development of diseases such as cystic fibrosis, sickle cell anemia, Huntington's disease, Tay-Sachs disease and Hemophilia. However, it's important to note that while genetics may play a role in the development of these diseases, other factors such as lifestyle and environment can also contribute. Further research in the field of genetics will continue to provide new insights into the genetic causes of human diseases and potential treatments.

  5. Tabulate the unique and common features for both plant and animal cells.  answer : Difference Between Plant cell and Animal cell The cell is the fundamental unit of life. All the life activities are carried out by cells. The organisms can be classified based on the number of cells present in them. Unicellular organisms are single-celled, while multicellular organisms have a large number of cells. Unicellular organisms are believed to be one of the earliest forms of life on earth. Eventually, more complex multicellular organisms evolved from these unicellular life forms over the aeons. Multicellular organisms have specialized cells with complicated cell organelles, which unicellular organisms typically lack. In an ecosystem, plants have the role of producers, while animals have taken the role of consumers. Hence, their daily activities and functions vary, and so does their cell structure. Cell structure and organelles vary in plants and animals, and are primarily clas...

  2.Compare the functions of starch and glycogen with a note about their different linkages. answers:  Difference between Starch, and Glycogen The table below shows the main differences between starch, cellulose and glycogen. Starch Glycogen It is a polymer of 𝜶-glucose subunits It is a polymer of 𝜶-glucose subunits It contains two types of polymers, amylose (unbranched and coiled) and amylopectin (branched) It is highly branched and similar to amylopectin The 𝜶-glucose subunits are joined by 1,4 glycosidic bonds in amylose and 1,4 and 1,6 glycosidic bonds in amylopectin The 𝜶-glucose subunits are joined by 1,4 and 1,6 glycosidic bonds Amylose is unbranched and amylopectin is branched It is highly branched It is the main storage carbohydrate in plants It is the main storage carbohydrate in animals and fungi Structure of Starch Starch is the main storage carbohydrate of plants. It is made up of 𝜶-glucose subunits. It contains two types of polymers, amylose and amylopectin....

1. Elaborate on the diversity of the root and shoot system of plants answer: Introduction Plants are one of the most important living organisms on earth. They have huge benefits for both humans and animals. A plant is made up of numerous parts. Distinct parts serve different purposes. The shoot system refers to the portion of the plant that protrudes above ground level, whereas the root system refers to the portion buried beneath the soil. The essential parts of a plant are: Roots Stem Leaves Flowers Fruits The study of plant organ tissue and cellular structure is known as plant anatomy. Cells serve as the fundamental building block of plants. Cells are organised into tissues, which are then organised into organs. Plant organs differ from one another in terms of their internal structure. The monocots and dicots are also observed to have diverse anatomical structures within angiosperms. Internal structures also exhibit environmental adaptations. Anatomy of Root All vascular plants have ...
