ایکسٹرا سرکلر ڈی این اے جو جین کے ویکٹر کے طور پر استعمال ہوتا ہے ____ ہے؟
Genome
Plasmid
Pilli
Ligase
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A plasmid is a small, extrachromosomal, circular DNA molecule that is commonly used as a vector in genetic engineering and molecular biology.
Plasmids are capable of replicating independently of the host cell's genome and can carry genes of interest.
It making them useful for gene cloning , expression, and transfer.
قدرتی طور پر پائے جانے والے انزائم کو بیکٹیریا کے ذریعے دفاعی کیمیکل کے طور پر استعمال کیا جاتا ہے ______؟
Defense protein
Restriction enzyme
Hydrolytic enzyme
Ligase enzyme
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Restriction enzymes are naturally occurring enzymes used by bacteria as a defense mechanism to protect themselves from viral infections.
These enzymes recognize specific DNA sequences and cut the DNA at those sites, preventing viral replication.
This defense strategy is known as the restriction-modification system.
بڑے پیمانے پر بیکٹیریا اگانے کے لیے کنٹینر کا استعمال کیا کہلاتا ہے؟
Chillers
Sterilizers
Fermenters
Ferments
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Fermenters are also known as bioreactors.
They are large containers used to grow microorganisms like bacteria, yeast, or cells on a large scale for various industrial applications, such as:
Production of biofuels Biopharmaceuticals Food processing Biotechnology research
الکحل ابال کے دوران روٹی کا آٹا _______ کی وجہ سے ہے؟
Methyl alcohol
CO2
Ethyl alcohol
H2O
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
During alcoholic fermentation , yeast converts sugars in the dough into carbon dioxide gas (CO2) and ethanol (ethyl alcohol).
The CO2 produced gets trapped in the dough , causing it to expand and rise.
This process is responsible for the light and airy texture of bread.
تیزابی تشکیل میں ______ سے پیدا ہونے والا لیکٹک ایسڈ؟
Pyruvic acid
Acetic acid
Citric acid
Glyceric acid
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Lactic acid is produced from pyruvic acid through a process called lactic acid fermentation.
It occurs in muscles during intense exercise or in certain microorganisms like Lactobacillus.
Pyruvic acid is a key intermediate in cellular respiration and is converted to lactic acid in the absence of oxygen.
زیادہ تر جاندار ______ پیدا کرنے کے لیے آکسیجن کا استعمال کرتے ہیں؟
ATP
Alcohol
Organic acid
Ecological pyramid
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Most living things, including animals, plants , and microorganisms, use oxygen (O2) to produce ATP through cellular respiration.
ATP is the primary energy currency of the cell , and it's essential for various biological processes like muscle contraction, nerve impulses, and biosynthesis.
حیاتیات کے ذریعہ بڑے پیمانے پر پیدا ہونے والی الکحل اور اینٹی بائیوٹکس ______ کا ایک علاقہ ہے؟
Environmental biotechnology
Fermentation
Biotechnology in industry
Medicinal biotechnology
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Biotechnology in industry refers to the use of biological systems , living organisms, or derivatives thereof, to develop new products and processes on a large scale.
This includes the production of alcohol, antibiotics, vaccines, biofuels, and other commodities.
انسانی جینوم کے مکمل گراف کا مطالعہ ______ نے کیا تھا؟
PCR
HGP (Human Genome project)
Medicine
Soma-clonal
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The Human Genome Project (HGP) was a global research effort that successfully mapped the entire human genome, identifying all its genes and their sequences.
The project was completed in 2003.
It's findings have revolutionized our understanding of human biology, disease, and treatment.
پہلے بائیوٹیکنالوجسٹ _____ تھے؟
Biologist
Agriculturist
Genetist
Farmers
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Farmers were the earliest biotechnologists , as they inadvertently manipulated the genetic makeup of crops and livestock through selective breeding and domestication.
This traditional form of biotechnology dates back thousands of years, long before the discovery of DNA and modern genetic engineering techniques.
مصنوعی ہیرا پھیری، دوا اور ڈی این اے کا دوبارہ ملاپ ____؟
Genetic engineering
Biotechnology
Molecular Biology
Genetics
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Genetic engineering, also known as genetic modification or biotechnology.
It is the artificial manipulation of DNA to alter the genetic code of an organism.
This can involve the transfer of genes from one organism to another, or the alteration of existing genes within an organism.
