No, RNA is synthesized from a single strand of DNA through a process called transcription. During transcription, the DNA helix unwinds, and an enzyme called RNA polymerase builds a complementary RNA molecule by pairing RNA nucleotides with the DNA template strand. This resulting single-stranded RNA molecule can then go on to perform various functions in the cell.

Difference between DNA replication and transcription?
1. Replication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. 2. There are different proteins involved in replication and transcription. 3. In replication, the end result is two daughter cells, while in transcription, the end result is a protein molecule. 4. In transcription, DNA serves as the template for RNA synthesis.
What do all organisms on earth have that are made of DNA?
Prokaryotes - Bacteria
What is the difference between a DNA molecule and RNA molecule?
There are some differences between DNA and RNA 1) RNA is usually single stranded whereas DNA is double stranded 2) DNA ( Deoxyribosenucleic acid) has one less oxygen atom than RNA (Ribosenucleic acid) 3) The nucleotides in DNA differ from an RNA strand as DNA contains a Thymine nucleotide and RNA contains an Uracil nucleotide.
What are three major differences between the structures of DNA and RNA?
RNA and DNA differ in these ways: (1) DNA has deoxyribose sugar, and RNA has ribose sugar. (2) DNA is made up of these four bases: adenine & guanine, cytosine & thymine; RNA is made up of adenine & guanine, cytosine & URACIL, the difference being that in RNA, uracil replaces thymine. (3) DNA is a double stranded molecule, and RNA is a single stranded molecule. (And for an optional 4)RNA can travel in and out of the nucleas of the cell. The DNA is stuck in the nucleas.
In DNA molecule how many polynucleotide strands are present?
2 polynucleotide strands make up a DNA and these strands are held togatehr by hydrogen bonds. In D.N.A there are 2 polynucleotide strands in R.N.A there is usually 1 polynucleotide strand.
How many strands is RNA made of?
in humans there is one strand of RNA, hence the name single-stranded RNA. However, in some viruses (such as HIV), there are double-stranded RNA made by the enzyme transcriptase.
HOW MANY STRANDS MAKES UP AN RNA MOLECULE?
Just 1 strand. DNA has 2.
The RNA molecule is made up of how many strands?
1

What is chromosome made up of?
strands of DNA
How does RNA differantiate from DNA if it is double strnded?
the following points differentiates double stranded RNA And DNA : 1. the RNA is loop structure at the end and not that independent strands of the DNA. this loop is calles R-loop, t includes a sequence if repeated poly A tail. 2. it contains poly a tail at the end but DNA doesn't.
How many polynucleotide strands do RNA have?
1
How does the structure of RNA differ than DNA?
In protein formation, mRNA carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). Ribosomes are composed of rRNA and protein; they can "read" the code carried by the mRNA. A sequence of three nitrogenous bases in mRNA specifies incorporation of an amino acid; tRNA brings the amino acids to the ribosomes, where they are linked into proteins.

How many strands does mRNA have?
a MRNA strand is a strand made up of messenger ribosenucleicacids

Flow chart of 8 steps of DNA replication?
The eight steps of DNA replication are: 1. DNA strands separate, 2. formation of replication fork, 3. RNA primase binds, 4. bases pair up, 5. elongation, 6. RNA primers removed, 7.termination, 8. repair. this can occur in any cell.
