The DNA molecule is a long term molecule which has to be highly conserved in order to be able to continue to provide the code for protein synthesis. Its double strand offers some protection against mutations, and allows mRNA to copy information off both strands simultaneously, increasing the efficiency of the event. mRNA is used to copy the DNA code and transport it to the cytoplasm, where it interacts with other RNA molecules to produce a protein product. When the protein has been made the mRNA is no longer used - it is a short term molecule. The strand needs to be able to pass through the rRNA and allow tRNA to add complementary bases to form the protein product. Mutations in the single stranded mRNA are not too catastrophic for the cells, as the molecule does not last for a great length of time, and further copies of the DNA can be made that are not muated in order to create the appropriate protein product.
What else can I help you with?
If DNA is described as a double helix how should mRNA be described-?
mRNA is like a single strand instead of a double strand. If DNA is like a twisted ladder, then mRNA is like a single half of that ladder, with only half the bases.
How do you translate the mRNA code?
Codes for the nuetrons in a basis of natural science when given a double helix structure follwed by a codon enzyme
What type of protein opens up DNA molecules to start transcription of mRNA?
RNA polymerase is the protein that unwinds and opens up the DNA double helix to initiate transcription of mRNA by reading and copying the DNA sequence into RNA.
What can leave the nucleus but DNA cannot?
Because mRNA is a single stranded molecule where as DNA forms a double helix. Therefore mRNA is a smaller molecule than DNA so can leave the nucleus ALSO mRNA has been processed post-translation. This means a 5' cap has been added and a 3' poly(A) tail has been added. This 5' cap, which DNA does not have, allows mRNA to leave the nucleus through nuclear pores. All above is good idea all , And me have something that need to include more. First time DNA can't leave from nucleus ,so DNA change to be nucleotide then mRNA go into nucleus and duplication ,A , T, C, G of DNA to be U,A,G,C. During mRNA get out from nucleus , mRNA will go to ribosomes to produce protein to take care cell.
How is the genetic code from the DNA transcribed and translated to make a functioning protein?
The double helix is split then transcribed into RNA... This RNA is then translated 3 bases at a time by ribosomes. Each 3 base combinations codes for one of 20 amino acids... This amino acids, being polar and non polar in nature, are linked in a chain which then folds in various 3d shapes known as a protein.

mRNA is like a single strand instead of a double strand. If DNA is like a twisted ladder, then mRNA is like a single half of that ladder, with only half the bases.
What is the shape of mRNA?
mRNA is most commonly linear but can form a duplex double strand just like DNA.
What are the differences between m-RNA and DNA?
DNA: Thymine double helix doesn't leave the nucleus deoxyribose Similarities: Adenine Guanine Cytosine nucleotide inside cell (nucleus) nucleic acid helix mRNA: Uracil Single strand leaves nucleus ribose sugar
What are two differences between transcription and DNA replication?
# Transcription is copying a section of DNA (a gene) onto a mRNA molecule. Replication is the copying the entire DNA molecule. # Transcription does not require primer for initiation.DNA replication use primer for initiation. # RNA transcription, mRNA copy of the active stand of DNA helix is made this process is carried by different enzyme & result is a single of mRNA.DNA replication double helix of DNA is duplicated into two identical double helix which are also identical to the mother DNA, this process is carried by specific enzyme
Compare and contrast the structure of tRNA and mRNA?
tRNA is a single-stranded molecule that forms a cloverleaf-like structure with three hairpin loops, while mRNA is also single-stranded but elongated and linear. tRNA carries amino acids to the ribosome and has an anticodon region that pairs with the codon on mRNA, whereas mRNA carries the genetic information from DNA to the ribosome for protein synthesis. Both molecules play key roles in translation, but have distinct structures and functions.
Which molecule is always single stranded?
RNA is always single stranded. DNA, on the other hand, can exist as either single-stranded or double-stranded.
Process of producing mrna from instructions in dna?
Transcription is the process by which mRNA is produced from the instructions encoded in DNA. During transcription, the DNA double helix unwinds, and an enzyme called RNA polymerase reads the DNA template and synthesizes a complementary mRNA strand. This mRNA strand then carries the genetic information from the DNA to the ribosomes for protein synthesis.
Is RNA single or double strand?
RNA is single stranded. DNA is double stranded. There are many types of RNA including mRNA, tRNA, and rRNA. mRNA and tRNA are involved in protein synthesis and the process of translation. mRNA and tRNA bind to the ribosome and form polypeptides or proteins that are released into the cell.
What kind of strand is the mRNA molecule?
The mRNA molecule encodes the protein product in the cell for translation. It is a double stranded, base-paired, ribonucleic acid that typically encodes a single gene, or protein, product.

Codes for the nuetrons in a basis of natural science when given a double helix structure follwed by a codon enzyme
What type of protein opens up DNA molecules to start transcription of mRNA?
RNA polymerase is the protein that unwinds and opens up the DNA double helix to initiate transcription of mRNA by reading and copying the DNA sequence into RNA.
When DNA functions as genes first a single strand of what is made?
When DNA functions as genes, first a single strand of mRNA (messenger RNA) is made through a process called transcription. This mRNA contains the genetic information necessary to produce proteins during the process of translation.
