We know, DNA is the main molecule by which scientists can learn about evolution by comparing the DNA structure between two different organisms.
But, in addition to DNA (which is most helpful & important) still, there are 3 molecules that can help us, They are:
1) RNA : - It is found in cytoplasm, as DNA transfers it's codes into RNA during Central dogma, it can help us in evolution studies.
2) Proteins: - Another helpful feature, into which RNA transforms in Central Dogma.
3) Pseudogenes: - It is also known as "Non-coding DNA" It is extra <span>DNA in a genome that do not get transcribed into RNA to synthesize proteins. They can also help us in Evolutionary studies.
Hope this helps!</span>
Answer:
Transcription and translation occur simultaneously in prokaryotes.
Explanation:
Prokaryotes lack membrane-bound organelles and therefore, do not have a nucleus. Transcription and translation occur in the cytoplasm. As soon as the required length of mRNA is being formed, ribosomes join it and start the process of translation. Prokaryotic genes lack introns. The primary transcript formed by transcription in prokaryotes does not undergo splicing.
On the other hand, the process of transcription occurs in the nucleus in eukaryotes while translation occurs in the cytoplasm. The primary transcript formed by transcription in eukaryotes undergoes modifications to remove introns and to add a poly-A tail and 5' cap. Post-transcriptional modifications and spatial separation of two processes in eukaryotes result in slower translation than prokaryotes.
Answer:
A planet is a celestial body that revolves around a star. In our solar system, Earth is the third planet from the sun. The word planet comes from the Greek planetes, which means "wanderer." Since ancient times, people have been fascinated by the wandering of celestial bodies in the night sky.

Answer:
the temperature of water drops and the density of it goes down as well.
Explanation:
The higher the altitudes, the lower the temperature.
At high altitudes, molecules tend to be more spread out, so the density of the molecules decrease.
