9.(a) Diabetics do not correctly produce or use their insulin hormone. The insulin hormone

helps control how much sugar is in your bloodstream. Millions of diabetics need to take

insulin. Insulin from cows and pigs has been used since the early 1900s to treat diabetes.

Now human insulin hormone can be mass-produced through genetic engineering

processes.

Pesakit kencing manis tidak dapat menghasilkan atau menggunakan insulin dengan

betul. Hormon insulin membantu mengawal kandungan gula dalam aliran darah .

Berjuta-juta pesakit kencing manis perlu mengambil insulin. Insulin daripada lembu dan

babi telah digunakan sejak awal 1900-an untuk merawat penyakit kencing manis.

Sekarang hormon insulin manusia boleh dihasilkan secara besar-besaran melalui

proses kejuruteraan genetik.

Diagram 9.1 shows a few stage that involves in the production of insulin hormone through

genetic engineering technology.

Rajah 9.1 menunjukkan sebahagian daripada peringkat yang terlibat dalam proses

penghasilan hormon insulin melalui teknologi kejuruteraan genetik.

(b) Genetic engineering (GE) is the manipulation of genetic material (DNA or genes) in a

cell or an organism in order to produce desired characteristics and to eliminate

unwanted ones. GE includes a range of different techniques with many different uses,

and can be applied to plants, animals and humans.

For example, the genetic modification of food is a form of GE that involves manipulating

the cells of plants.

Kejuruteraan genetik (GE) adalah manipulasi bahan genetik (DNA atau gen) di dalam

sel atau organisma untuk menghasilkan ciri-ciri yang dikehendaki dan untuk

menghapuskan organisma yang tidak diingini. GE termasuk pelbagai teknik yang

berbeza dengan kegunaan yang berbeza, dan boleh digunakan untuk tumbuh-

tumbuhan, haiwan dan manusia. Sebagai contoh, pengubah suaian genetik makanan

adalah satu bentuk GE yang melibatkan memanipulasi sel-sel tumbuh-tumbuhan.

Diagram 9.2 shows two tomato leaves which have been exposed to a bacterial

pathogen, Pseudomonas syringae. Leaf A is the normal leaf show disease when

Answer all questions. Jawab semua soalan.

Question 1 Soalan 1 A group of students were provided with article above as guidance for them to conduct an experiment

to investigate the percentage of Vitamin C in different types of vegetables. They believe that

vegetables contain higher percentage of Vitamin C compared to fruits.

Sekumpulan pelajar telah dibekalkan dengan artikel di atas sebagai panduan untuk mereka

menjalankan sebuah eksperimen untuk menyiasat peratus Vitamin C dalam jenis sayuran yang

berbeza. Mereka percaya bahawa sayur-sayura mempunyai peratusan Vitamin C yang lebih tinggi

berbanding buah-buahan

The following steps were carried out.

Step 1: 20 grams of Cauliflower are blended with 20 ml of distilled water using a blender in 30

seconds

Step 2 : Suspension is filtered and the filtrate is collected. Fill a syringe with needle with 5 ml of

Cauliflower filtrate and leaf it a side.

Step 3 : 1 ml of DCPIP solution is measured using measuring cylinder and pour it into a specimen

tube

Another name for Vitamin C, a nutrient found in fresh fruits and vegetable is called Ascorbic

Acid. Among good sources of Vitamin C are citrus fruits like oranges, lemons, limes and

grapefruits, berries, tomatoes, green peppers, cabbage, broccoli and spinach. Currently the

recommended dietary allowance (RDA) for vitamin C is 50-60 mg/day for adults; 35 mg/day

for infants; 40-45 mg/day for children.

Stein, Jay H. “Ascorbic Acid(Vitamin C) Deficiency.” In Internal Medicine. St Louis: Mosby 1998

Nama lain bagi Vitamin C, nutrien yang dijumpai di dalam buah-buahan segar dan sayur-

sayuran dipanggil Asid Askorbik. Antara sumber Vitamin C adalah buah-buahan sitrus

seperti oren, limau, dan anggur, beri, tomato, cili hijau, kobis, brokoli dan bayam. Buat masa

ini, jumlah pemakanan cadangan (RDA) untuk Vitamin C adalah 50-60 mg/hari untuk

dewasa; 35mg/hari untuk bayi; 45mg/hari untuk kanak-kanak.

Stein, Jay H. “Ascorbic Acid(Vitamin C) Deficiency.” In Internal Medicine. St Louis: Mosby 1998



Step 4: By using the syringe prepared in Step 2, deep in the needle in to the solution and pour in the

Cauliflower filtrate in to 1ml DCPIP solution in the specimen tube.

Step 5: By using the needle, stir the solution slowly until it is decolorized.

Step 6: Measure and record the final reading of the syringe.

Step 7: Repeat Step 1-6 by using Broccoli and Lime. While repeat Step 2-6 by replacing filtrate with

Ascorbic Acid.

Question 2

Soalan 2

Diagram 2 is an illustration of Hulu Selangor, Selangor area where there is a palm oil

farm near Gunung Nuang as well as few lots of bungalow 5 km down a stream which is

known as Sungai Congkak. As shown in the diagram below, Sungai Congkak is a river

that flows from up the stream towards the factory and bungalow lots.

August, 24 - Statistics from Jabatan P dan Saliran, Selangor shows there were few

reports from people leaving in the bungalow lots saying that the Sungai Congkak is

badly polluted due to pollutants released from the palm oil factory. They believe that the

disposable sewage enhance the growth of microorganism. Due to this contamination,

the reports also mentioned about children who were swimming in the river were

diagnosed with severe rashes.

Rajah 2 merupakan illustrasi kawasan Hulu Selangor, Selangor di mana terdapat lading

kelapa sawit berdekatan dengan Gunung Nuang serta beberapa lot banglo 5km

menuruni susur sebuah sungai yang dikenali sebagai Sungai Congkak. Seperti yang

ditunjukkan di dalam rajah di bawah, Sungai Congkak merupakan sungai yang mengalir

dari atas menuju ke kilang dan lot banglo.



As the representative of Jabatan Alam Sekitar, you are required to design a laboratory

experiment to study the degree of water pollution at three different stations along the

river.

Sebagai wakil Jabatan Alam Sekitar, anda dikehendaki untuk merancang sebuah

eksperimen makmal untuk mengetahui tahap pencemaran air di tiga stesen yang

berbeza sepanjang sungai tersebut.
