Why do scientists think RNA may have evolved before DNA?

because RNA depend to DNA.


Why could RNA evolve before DNA?

I think It's because RNA is less complex than DNA.


What must happen to a DNA molcule before RNA polymerase can make RNA?

Before RNA polymerase can make RNA, the DNA molecule must be unwound and the double helix separated to expose the sequence of nucleotides that will be used to transcribe the RNA. This process is facilitated by proteins that help open the DNA molecule for transcription.


What enzyme matches RNA nucleotides to complementary DNA nucleotides?

The enzyme that matches RNA nucleotides to complementary DNA nucleotides is called reverse transcriptase. It is used by retroviruses like HIV to convert their RNA genome into DNA before integrating it into the host cell's genome.


Did RNA originate before DNA?

Scientist believe so.


What enzyme transcribes DNA?

The enzyme that transcribes the DNA into RNA is called RNA polymerase.


What must happen to a DNA molecule before RNA polymerase can make RNA?

The DNA molecule must first unwind and separate into two strands. This process is called transcription, during which RNA polymerase can then read and transcribe one of the DNA strands to synthesize RNA.


What is nucleic acid that stores and transmits genetic information?

While RNA can exist in a double stranded form, DNA functions as genetic information storage. In addition, DNA contains thymine (T), whereas RNA contains uracil (U), so the answer is DNA.


Is there another nucleic acid other than DNA and RNA?

Yes, more nucleic acids exist.


What exist in the mitochondria?

There are several things. Some are circular DNA,RNA,enzymes,organic molecules etc


In which organelle is DNA kept and RNA transcript?

DNA is kept in the nucleus, while RNA transcription occurs in the nucleus before the mRNA moves to the ribosomes in the cytoplasm for translation.


What is the name of the nucleotides have no DNA and no RNA?

Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
