Answer: The correct answer for the fill in the blank is- Transcription.
Transcription is a genetic process by which DNA ( deoxyribonucleic acid) is converted into mRNA ( messenger RNA) with the help of enzyme RNA polymerase.
During this process, the two strands of DNA are first separated so that the template DNA ( that is having polarity 3' to 5') is exposed.
Using the template strand, RNA polymerase adds the RNA nucleotides according to the Watson and Crick base pairing and thus mRNA transcript is assembled.
Purines have 2 rings pyrimidines have 1 ring.
Answer:old earth:
At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.The early Earth's atmosphere had a very low concentration of oxygen compared to today. 2.4 billion years ago, the oxygen concentration in the atmosphere was less than one part per billion and the iron concentration in the ocean was much higher than today.At its beginning, Earth was unrecognizable from its modern form. new earth:
"Today's Earth (TE)" is JAXA's land surface & river simulation system developed under the joint research with University of Tokyo. The system distributes & visualizes various hydrological products and their magnitudes for disaster monitoring and hydrological research.
The early Earth was very different from our Earth today. The early Earth experienced frequent impacts from asteroids and meteorites and had much more frequent volcanic eruptions. There was no life on Earth for the first billion years because the atmosphere was not suitable for life.
