Which came first in the evolution of life, DNA or RNA?
RNA likely came first in the evolution of life before DNA. RNA is thought to have been an early molecule that played a crucial role in the development of life on Earth.
Was it DNA or RNA come first?
Currently, scientists believe that RNA likely came first in evolution before DNA. This is because RNA is more versatile and can store genetic information, catalyze reactions, and replicate itself, making it a prime candidate for the earliest stages of life.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What base does RNA have that DNA does not have?
RNA has the base uracil that DNA does not have.
What are the 30 differences between DNA and RNA?
Comparing DNA and RNA, some key differences include: DNA is double-stranded, while RNA is single-stranded; DNA contains deoxyribose sugar, RNA contains ribose sugar; DNA has thymine base, RNA has uracil base; DNA is found in the nucleus, RNA is found in the cytoplasm; DNA is stable, RNA is less stable; DNA is the genetic material, RNA is involved in protein synthesis. These are just a few of the many distinctions between DNA and RNA.

How could all three of them have come into existence at the same time since RNA DNA and proteins all need each other for life to continue?
RNA doesn't need proteins nor does it need DNA. RNA probably came first. And it is known that RNA can form peptide bonds which can make proteins. DNA would have come later. They don't need each other, from an evolutionary standpoint. Modern DNA and RNA and proteins are interlocked, but earlier forms clearly weren't.
Do scientists think DNA or RNA was made first?
It's not possible to say based on our current knowledge. It is likely that the earliest forms of life replicated using RNA rather than DNA. In glass vessels in the Lab we have, not all that easily, combined substances that produced Rna particles capable of, if not self-replication, then the replication of other Rna strands in the same solution. With DNA being as fragile as a strand of fiberglass, and as such it cannot exist without being wound around histone proteins, this shows that Rna Way came first.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
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.
What is the first step in decoding genetic messages?
The first step in decoding genetic messages is transcription, where the DNA sequence is copied into a messenger RNA (mRNA) molecule by RNA polymerase.
What does the synthesis of a new strand of DNA begin?
Following the initiation of DNA replication, the first step is the synthesis of a short RNA primer.
What is the substance in RNA but not DNA?
An uracil base is in RNA but not in DNA
What base does RNA have that DNA does not have?
RNA has the base uracil that DNA does not have.
Are DNA and RNA carbohydrates?
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.
