How does DNA lead scientists to better classify organisms? How do the bases bond together in DNA? What is the DNA organization? How is it related to gene expression? How does the DNA of prokaryotic cells differ from the DNA of eukaryotic cells?
List down the differences between sexual and asexual reproduction. How do the terms reproduction and recombination differ? What are the similarities between the sexual and asexual reproduction of plants? How does conjugation differ from reproduction? How do mitosis and meiosis differ from each other?
a person's veins are completely unique. Twins don't have identical veins, and a person's veins differ between their left and right sides. Many veins are not visible through the skin, making them extremely difficult to counterfeit or tamper with. Their shape also changes very little as a pe...
The genetic material you carry in the form of nuclear DNA are the result of a merger between your mother's and father's DNA — a merger called recombination. mtDNA, however, almost exclusively derives from your mother. This is because the egg of a female human contains lots of mtDNA, whi...
Protein coding features can emerge de novo in non coding transcripts, resulting in emergence of new protein coding genes. Studies across many species show that a large fraction of evolutionarily novel non-coding RNAs have an antisense overlap with protei
The impact of conflict on the evolution of organismal biology changes in response to how organisms reproduce3. For sea urchins or abalone, which cast their gametes to the whims of ocean currents, conflict shapes the interface between sperm and eggs4,5. For organisms with internal fertilization, ...
If you're planning on doing the installation yourself, there are a few things to consider. The general suggestions below will give you an idea of what's involved, but dual flush toilet models differ, so pay close attention to the instructions that come with the dual flush toilet model you...
How does DNA differ from person to person? DNA Differences You may have heard deoxyribonucleic acid (DNA) referred to as ''the building block of life,'' and indeed it is what makes us who we are and what makes us different from other people. Though the basic structure of all DNA is ...
b) How does it differ from other DNA/chromosomal entities? Nucleus: It is an essential eukaryotic cell organelle, which houses the nuclear material. The eucaryotic nuclear material shifts shape and form depending on the stage of the cell cycle. Prokaryotic cells lack a nucleus, their n...
