Teminism is commonly known as reverse transcription, dicovered by Temin and Baltimore in 1978. It is a theory that explains the synthesis of DNA using RNA as a template.

What is meant by Teminism?
Teminism is a theoretical concept. nIt is actually know as Reverse Transcription. This was first discovered in 1978 by Temin and Baltimore. In molecular biology, the theory of Teminism explains that RNA can serve as a template for the creation of DNA, that is, RNA can synthesise the DNA.
What is central dogma and Teminism?
Hint: A theory related to the synthesis of DNA. Complete answer: Teminism was first discovered in 1978 by Temin and Baltimore. Teminism is a theoretical concept that means reverse transcription. ... - Central dogma includes: making of new DNA from existing DNA, making new RNA from DNA, and making new proteins from RNA.
What is meant by Operon?
Operon: A set of genes transcribed under the control of an operator gene. More specifically, an operon is a segment of DNA containing adjacent genes including structural genes, an operator gene, and a regulatory gene. An operon is thus a functional unit of transcription and genetic regulation.
What is the sequence of pribnow box?
The Pribnow box (also known as the Pribnow-Schaller box) is a sequence of TATAAT of six nucleotides (thymine, adenine, thymine, etc.) that is an essential part of a promoter site on DNA for transcription to occur in bacteria.
What is split gene in biology?
An interrupted gene (also called a split gene) is a gene that contains expressed regions of DNA called exons, split with unexpressed regions called introns (also called intervening regions). Exons provide instructions for coding proteins, which create mRNA necessary for the synthesis of proteins.
What is a Cistron Toppr?
Cistron is the segment of DNA having information for synthesis of a particular protein or RNA. The segment encodes for the synthesis of RNA or polypeptide of protein molecule.
What are genes chemically?
Chemical structure of genes
Genes are composed of deoxyribonucleic acid (DNA), except in some viruses, which have genes consisting of a closely related compound called ribonucleic acid (RNA). A DNA molecule is composed of two chains of nucleotides that wind about each other to resemble a twisted ladder.
Why RNA is not suitable genetic material in comparison with DNA explain?
While DNA contains deoxyribose, RNA contains ribose, characterised by the presence of the 2′-hydroxyl group on the pentose ring (Figure 5). This hydroxyl group make RNA less stable than DNA because it is more susceptible to hydrolysis.
What did Jacob and Monod discover?
In 1958 Monod and Jacob began to collaborate on studies of the regulation of bacterial enzyme synthesis. One of their first major contributions was the discovery of regulator genes (operons), so called because they control the activities of structural genes.
What is RT in biology?
A reverse transcriptase (RT) is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. ... In retroviruses and retrotransposons, this cDNA can then integrate into the host genome, from which new RNA copies can be made via host-cell transcription.
What is the best definition of an operon?
Operon: A set of genes transcribed under the control of an operator gene. More specifically, an operon is a segment of DNA containing adjacent genes including structural genes, an operator gene, and a regulatory gene. An operon is thus a functional unit of transcription and genetic regulation.
What is operon hypothesis?
Operon Hypothesis – Enzyme Induction
In bacteria, genes that code for proteins required for the same metabolic or biosynthetic pathway are often clustered in groups called operons The lac operon in E. ... The operator gene binds the repressor protein, which determines whether the structural gene is switched on or off.
What is an operon Class 12?
- Operons are regions of DNA that are made of a group of related genes. They consist of a promoter region, an operator, and multiple related genes. ... - The location of the operator i.e. the place where it is present decides its regulation i.e. it either allows or prevents transcription of the genes into mRNA.
