Why is RNA necessary to act as a messenger?
RNA is necessary to act as a messenger because it carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized. It serves as a template for protein synthesis and helps in decoding the genetic information stored in the DNA. RNA is also more versatile and can move in and out of the nucleus, facilitating the efficient transfer of genetic information.
Why is RNA necessary to act as a maessanger?
RNA is necessary to act as a messenger because it carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized. It serves as a temporary copy of the genetic code, allowing the cell to produce proteins based on the instructions encoded in the DNA.
Are almost all enzymes proteins?
Yes, almost all enzymes are proteins. Enzymes are a type of protein that act as biological catalysts, speeding up chemical reactions in living organisms. There are also some RNA molecules called ribozymes that can act as enzymes.
What enzyme is necessary for transcription?
The enzyme RNA polymerase transcribes DNA. This enzyme initiates transcription, joins the RNA nucleotides together, and terminates.
Explain three characteristics that distinguish DNA of rna?
RNA is single-stranded, while DNA is double-stranded. RNA contains ribose sugar in its backbone, while DNA contains deoxyribose sugar. RNA uses uracil as one of its nitrogenous bases, while DNA uses thymine.
What are the three kinda of RNA?
The three types of RNA are: mRNA (messanger RNA), rRNA (ribosomal RNA), and tRNA (transfer RNA).
What is messanger RNA?
Carries the DNA message from the nucleus to the ribosome.
How does a cell get the genetic code from its location to the site of protein synthesis?
By messanger RNA
What is the job of Messanger RNA?
Messenger RNA (mRNA) is a molecule of RNA encoding a chemical "blueprint" for a protein product. mRNA is transcribed from a DNA template, and carries coding information to the sites of protein synthesis: the ribosomes.
Which purine or pyrimidine bases are not present in the messanger RNA m-RNA is it adenine or guanine or cytosine or thymine or uracil?
thyamine isn't present in mRNA its place is taken by uracil
What type of RNA makes a copy directly from DNA?
Messenger RNA (mRNA) is the type of RNA that is transcribed directly from DNA during the process of transcription. It carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm for protein synthesis.
What tasks does messanger RNA perform during protein synthesis?
mRNA carries a copy of our DNA, our genetic information and is used in the synthesis of these proteins.
How does DNA get made into protein?
DNA creates messanger RNA by transcription and this mRNA reaches the site of protein synthesis. The message of type of protein to be synthsized is received by ribosomes from RNA and the ribosomes make protein from amino acids present in the cytoplasm.
What is a characteristic of hormones 1 act as a messanger molecule 2 act as a buffer in the bloodstream 3 inactivate bacteria or 4 coordinate visual responses?
Act as messenger molecules
Why is RNA necessary to act as a messenger?

Can RNA act as a precursor molecule?

What is considered to be the first biological catalyst when originated on earth?
The first biological catalyst that originated on Earth is believed to be RNA (ribonucleic acid). RNA can act as an enzyme, carrying out chemical reactions necessary for life. This hypothesis is supported by the fact that RNA has both information storage capabilities (like DNA) and catalytic abilities, making it a potential precursor to the evolution of more complex proteins.
