What is mRNA and why is it used instead of another DNA strand?
The mRNA is formed on DNA strand after transcription to carry the specific message to synthesize proteins by ribosomes in the cytoplasm. Since RNA can move from nucleus to the cytoplasm (not DNA), mRNA is used for sending messages to synthesize specific proteins.
Mrna carries the info for making proteins to the?
mRNA carries information from the DNA in the nucleus out into the cytoplasm of the cell. mRNA carries the information for making proteins to the ribosomes.
What is polycystronic mRNA?
mRNA that codes for multiple proteins (e.g. lac operon)
What r two basic steps of polypeptide synthesis?
The 2 basic steps of polypeptide synthesis are:Transcription - the synthesis of mRNA from a DNA template. Only one strand of DNA is copied, and a single gene may be transcribed thousands of times.Translation - the process where ribosomes synthesize proteins using the mature mRNA transcript produced during transcription. The ribosome attaches to mRNA, and then moves along the mRNA adding amino acids to the growing polypeptide chain.
What are Eukaryotic cell organelles that synthesize proteins and process proteins called?
ribosomes
How is mRNA used by cell?
Transcription takes the information encoded in DNA and encodes it into mRNA, which then heads out of the cell’s nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.
Does DNA synthesize proteins?
DNA does not synthesize proteins. But they code for the message needed for the proteins. DNA transcribe mRNA first in the nucleus and send out to cytoplasm. The protein synthesis machinery in the cytoplasm (ribosome) will synthesize proteins according to the message in mRNA.
What are proteins synthesised?
Proteins are synthesized in cytoplasm. mRNA is transcribed in the nucleus by DNA which will be exported to cytoplasm. The mRNA together with the machinery such as ribosomes, tRNAs and enzymes synthesize proteins.
Why are exons important?
Exons code for proteins. Exons are parts of DNA that are converted into mature messenger RNA.. From there, mRNA undergoes translation where mRNA is used to synthesize proteins.
How is mRNA is used by a cell?
Transcription takes the information encoded in DNA and encodes it into mRNA, which then heads out of the cell’s nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins.
What is mRNA and why is it used instead of another DNA strand?

What is the process in which ribosomes synthesize proteins using the mRNA transcript?
Translation of mRNA into a protein occurs in the ribosomes.
Ribosomal rna brings what to ribosomes for protein synthesis?
The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell’s nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins. RNA polymerase is necessary for the process to occur.
What are the functions of genes and proteins respectively?
Genes are a segment of DNA which codes for a RNA or proteins. In any case, the first process is transcription of mRNA that will be then transported to cytoplasm. RNA may or may not synthesize proteins depending on the nature and message coded in it. mRNA usually interact with tRNA and ribosomes to make proteins.
Why do you have ribosomes?
Ribosomes are a minute particle that consists of RNA and similar proteins that are located in the cytoplasm of living cells. Their purpose is to bind mRNA and tRNA in order to synthesize polypeptides and proteins.
What makes up proteins?
amino acidsAmino acids make up proteins. It happened in cytoplasm of the cell where mRNA, ribosomes, tRNA work together to synthesize proteins. The message for the proteins sequence is coded in DNA.
MRNA is needed to synthesize what in the cytoplasm?
protein
