Yes, translation is an anabolic process, where proteins are synthesised from amino acids using the genetic information present in mRNA. mRNA is... View Article
Reverse transcription refers to the formation of complementary DNA (cDNA) using RNA as a template. It occurs when viruses, having RNA as genetic... View Article
In negative regulation of transcription, a repressor protein binds to the operator region and inhibits the transcription by RNA polymerase. It... View Article
Prokaryotes do not have a nucleus and other organelles. Prokaryotic cells divide by binary fission, which is similar to mitosis but is less... View Article
Protists are unicellular eukaryotes. Protists undergo meiosis during sexual reproduction. They produce gametes that undergo syngamy to produce a... View Article
Sporic meiosis refers to the formation of spores by meiosis in the sporangia of sporophytes. Pteridophytes show sporic meiosis, i.e. formation of... View Article
Yes, DNA replication occurs at the S-phase to produce identical sister chromatids. It is followed by two rounds of division to produce 4 haploid... View Article
Germ cells undergo meiosis, e.g. primary spermatocytes and primary oocytes in males and females, respectively and in pollen mother cells and... View Article
Without meiosis, the number of chromosomes will not remain constant in a species across generations and will be duplicated every time after... View Article
Meiosis is a reduction division, which leads to the formation of four daughter cells having half the number of chromosomes as the parent cell.... View Article
Meiosis occurs in the ovaries of a female. Primary oocytes undergo meiosis during oogenesis, i.e. the formation of mature female gametes or eggs.... View Article
Meiosis is a reduction division, wherein the number of chromosomes is reduced to half in the daughter cells. Male and female gametes are formed... View Article
Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes... View Article
Yes, plants also undergo mitosis and meiosis similar to animal cells. Mitosis is required for growth, asexual reproduction and regeneration.... View Article
Mitosis is the process by which an organism grows and repairs damaged tissues. Some organisms use mitosis to reproduce asexually. The offspring... View Article
The shortest phase of mitosis is anaphase, which comes after metaphase. In this phase, the sister chromatids separate and move towards opposite... View Article
Mitosis occurs rapidly in the growing regions, the dermis of the skin, where cells are replaced continuously, the region of wound healing, etc.... View Article
If cytokinesis does not occur after nuclear division (karyokinesis) then it will result in a multinucleated cell with more than one nuclei.... View Article
