Name the transgenic crop in which three genes for synthesis of vitamin A are introduced through the technique of genetic engineering.
-
Kalyan Sona wheat
-
Sweet sorghum
-
Hybrid bajra
-
Golden rice
In genetic engineering, which of the following is used?
-
Plasmid
-
Plastid
-
Mitochondria
-
Endoplasmic reticulum
Genetic engineering mainly aims at the transfer of genes of desired protein products between the organisms. Plastids are double membrane bound organelles that serve as the site for photosynthesis. Mitochondria are double membrane bound eukaryotic cell organelles that serve as the site for cellular respiration, produce an enormous amount of energy. ER is eukaryotic organelle with a network of tubules, vesicles, and cisternae within the cells. It serves to synthesis and transport of proteins and lipids. Plasmids are low molecular weight extrachromosomal DNA that carries origin of replication, restriction sites and selectable markers to confer readily selectable phenotypic traits on host cells. Plasmids require very few genes for their own replication and rest of it can be deleted and foreign sequences can be added to the plasmid which in turn makes them a suitable candidate to serve as a vector for gene transfer. Thus, the correct answer is option A.
Which of the following bacteria are used in study of 'genetics'?
-
E. coli
-
Bacillus
-
Pseudomonas
-
Rhizobium
Which of the following is related with genetic engineering?
-
Golgi apparatus
-
Lysosomes
-
Mitochondria
-
Plasmid
Genetic engineering mainly aims at the transfer of genes of desired protein products between the organisms. Lysosomes are the suicidal bags of cell that digest and remove the wear and tear organelles and molecules from the cell. Golgi body consist of flattened sacs stacked on each other, that serve to processes secretory and synthetic products from the ER and then transport the finished products into cell part or secretes them to the outside of the cell. Mitochondria are double membrane bound eukaryotic cell organelles that serve as the site for cellular respiration, produce an enormous amount of energy and therefore are also known as a power house of cell. Plasmids are low molecular weight extrachromosomal DNA that carries origin of replication, restriction sites and selectable markers to confer readily selectable phenotypic traits on host cells. Plasmids require very few genes for their own replication and rest of it can be deleted and foreign sequences can be added to the plasmid which in turn makes them a suitable candidate to serve as a vector for gene transfer. Thus, the correct answer is option C.
What is the trade name of genetically engineered insulin?
-
Anulin
-
Beta insulin
-
Humilin
-
Gilbert's insulin
Genetically engineered insulin is sold with commercial name 'humulin'.
Radiology deals with the study of
-
UV rays
-
Gamma rays
-
Cosmic rays
-
X-rays
Radiology is a medical specialty that uses imaging to diagnose and treat disease seen within the body. Radiologists use a variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and magnetic resonance imaging (MRI) to diagnose or treat diseases.
Which is considered a superior method for identification of urine sugars?
-
Endoscopy
-
Thin layer chromatography
-
Electrocardiogram
-
Tomography
- Thin-layer chromatography is a method that is used for the separation and identification of the amino acids and sugars.
- There are different substances that may be present in the urine which is excreted by an organism.
- Generally, the amount of sugar that is excreted by humans is less.
- In the case of diabetic patients, the sugar in the urine can be detected by this method of chromatography in which there is a thin layer of silica gel and the solvent is used with respect to the sugars.
- The solvent flows and allows the separation of the different molecules.
- Thus, the correct answer is option B.
