Genetic Engineering Interview Questions and Answers
Question - 21 : - What Happens In Dislexia, Genetic Or Brain Damage ?
Answer - 21 : -
Dyslexia is an unexpected impairment in reading and spelling despite a normal intellect.
Dyslexia results from a disfunction in visual memory and visual perception due to a delayment in maturation. Most dyslexics also display poor writing ability.
Dyslexia is a classical primary reading disorder and should be differentiated from secondary disorders such as mental retardation, educational or environmental deprivation, or physical/organic diseases.
The disorder results as a combination of genetic and environmental causes, which can induce variations in the behavioral, cognitive, and physiological measures related to reading disability. Dyslexia was previously called congenital word blindness.
Question - 22 : - What Are Teaspoons?
Answer - 22 : -
These are specific sequences in DNA of all oranisms ,viruses which can get inserted to any other DNA.
So called as jumping genes discovered by by Barbara Mc clintosh.They may be replicative /non replicative.They are classified as composite ,Is Cut &paste .Retroposons etc.They bring about mutation (frame shift )& also oncogenic .some of the egs are LINES ,SINES In humans ,gal genes in drosophila.
Question - 23 : - What Is Mutation?
Answer - 23 : -
Sudden heritable change in dna or chromosomes is called mutation. There are agents which cause mutations called mutagens. Due to mutations many abnormalities will appear in new generations which may be useful or harmful.
Question - 24 : - What Is Co-dominance ?
Answer - 24 : -
co-dominance means there are always two alleles for any character. If the two alleles are equally dominant over one another and neither of them exprasses to outside is called codominance.Here neither of the character appares in offspring.This phenomenon can be clearly explained by taking the example of drosophila.
Question - 25 : - What Is The Difference Between Sex-linked And Sex- Influenced Diseases?
Answer - 25 : -
In Sex linked diseases the defeceted genes are present on the sex chromosomes attached to them whereas in Sex influenced diseases defective genes are present on the other chromosomes but affects the sex chromosomes.
Question - 26 : - What Is Inbreeding ?
Answer - 26 : -
If the breeding is done in between the plant sps whose parents ae identical such type of breeding is called inbreeding.Due to inbreeding internal resistance developes and desirable characters will increases.
Question - 27 : - What Is Inbreeding ?
Answer - 27 : -
If the breeding is done in between the plant sps whose parents ae identical such type of breeding is called inbreeding.Due to inbreeding internal resistance developes and desirable characters will increases.
Question - 28 : - What Areproteomes And Proteomics.?
Answer - 28 : -
The proteome is the complement of proteins expressed by an organism, tissue or cell type. Proteomics, the study of proteomes, characterisation of patterns of gene expression at the protein level or defined more widely as the link between proteins and genomes.
Importance of proteomics is to identify proteins with altered levels of expression.
Changes in protein expression levels are associated with disease states, drug treatment, cellular stress, genetic manipulation or changes in metabolism.
Question - 29 : - What Is Genome?
Answer - 29 : -
complete set off genes in an organism is called genome.
Question - 30 : - What Is The New Theory Of Introns?
Answer - 30 : -
The introns-late theory portrays introns as molecularparasites, mildly deleterious in that they consumemetabolic resources of organisms that must removethem from their transcripts.
