There are many reasons why scientists think RNA came before DNA. RNA is found in viruses and some bacteria which were likely around before more complex organisms.
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.
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.
Yes, more nucleic acids exist.
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.
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
because RNA depend to DNA.
I think It's because RNA is less complex than DNA.
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.
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.
Scientist believe so.
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
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.
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.
Yes, more nucleic acids exist.
There are several things. Some are circular DNA,RNA,enzymes,organic molecules etc
