What else can I help you with?
Why do scientists think RNA may have evolved before DNA?
because RNA depend to DNA.
Why does influenza have RNA?
Influenza is an RNA virus because its genetic material is made up of RNA. RNA viruses like influenza are able to mutate more rapidly than DNA viruses, which contributes to the virus's ability to evolve quickly and evade host immunity.
Did RNA exist before DNA?
It is believed that RNA predates DNA in the evolution of life on Earth. RNA is thought to have played a crucial role in early life processes, such as catalyzing chemical reactions and storing genetic information. Over time, DNA likely evolved from RNA as a more stable and efficient means of storing genetic information.
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.
A mutation in this section of DNA could influence the binding of RNA polymerase to the DNA?
A mutation in the promoter region of DNA, where RNA polymerase binds to initiate transcription, could influence the binding of RNA polymerase. This could alter gene expression by affecting the efficiency or ability of RNA polymerase to initiate transcription of the gene.
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 the process of combining rna from DNA called?
The process of combining RNA from DNA is called transcription. During transcription, an enzyme called RNA polymerase reads the DNA template strand and synthesizes a complementary RNA strand. This newly formed RNA molecule can then undergo further processing before being translated into proteins.
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 starting material of transcription?
In transcription RNA is copied from DNA,so either could be considered the starting point.
