No, only retroviruses show reverse transcription. They contain RNA in their genome. The conversion of RNA to DNA is the reverse of the central... View Article
Yes, reverse transcriptase needs a primer. DNA oligonucleotide is used as a primer. Oligo(dT) is often used as a primer. In the retroviral... View Article
Reverse transcription is the process by which RNA is transcribed into cDNA. Retroviruses reverse transcribe their RNA genome and insert it into... View Article
Transcription is the process of formation of RNA from DNA template. Reverse transcription is the opposite process of transcription, i.e. RNA... View Article
Francis Crick proposed the central dogma of molecular biology in 1958, which tells about the flow of genetic information from DNA to RNA to... View Article
RNA viruses or retroviruses, transcribe RNA into DNA by reverse transcription so they are known as an exception of central dogma. Central dogma... View Article
Exons are coding regions of mRNA, which code for amino acids. Exon refers to the DNA sequence in the gene and its corresponding sequence in the... View Article
Splicing is the process by which pre-mRNA is processed. Introns or non-coding regions are removed and exons or coding regions join together to... View Article
Stop codon is a triplet of nucleotides sequence presence on mRNA, which terminates the process of translation and protein synthesis. These do not... View Article
No, detritivores are not secondary consumers. They are decomposers, they feed on dead and decaying plants and animals as well as on their faeces.... View Article
Humus is the dark coloured amorphous substance produced by decomposition of detritus. Humus undergoes decomposition at a slow rate. Humus is... View Article
Something, which used to be alive or was part of the living system is considered biotic even after it is dead. They are considered abiotic once... View Article
No, the food chain only starts with autotrophs or producers. Deer are heterotrophs and they can not make their own food. Further reading:... View Article
If an organism is removed from a food chain, it will disrupt the energy flow in the ecosystem. The organisms that depend on it will also die. The... View Article
Yes, humans are a part of the food chain. Humans are omnivore, they feed on both plants and animals. Plants are present at the 1st trophic level,... View Article
Energy is transferred from one trophic level to another in the food chain. Some of the energy consumed is utilised to carry metabolic activities... View Article
Food chain existing in the aquatic ecosystem often starts with algae or phytoplankton as producers, then zooplankton, which feed on them.... View Article
Snails are detritivores. They feed on dead organisms and waste material. detritivores are also a type of decomposers. Other decomposers are... View Article
