What else can I help you with?
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 new product is formed at the DNA strand?
RNA does, in contrast to DNA, form short double strand structures on itself, thereby forming so called stem and loop structures.
Why describes the main purpose of RNA polymerase during transcription?
it uncoils and unzips the double helix at the weak hydrogen bonds between the nitrogenous bases. Free RNA nucleotides match with the complementary DNA strand and form mRNA which then moves out of the nucleus through the pore an continue the protein synthesis through translation.
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.
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.

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
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 is the shape of mRNA?
mRNA is most commonly linear but can form a duplex double strand just like DNA.
How many strands of nucleotides make up DNA double helix?
A DNA double helix is made up of two strands of nucleotides that are complementary to each other. Each strand consists of a sequence of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G).
What unwinds a segment of DNA to make mRNA?
During transcription, an enzyme called RNA polymerase unwinds the DNA double helix at the beginning of a gene segment to expose the nucleotide sequence that will be used to create messenger RNA (mRNA). This unwinding allows the RNA polymerase to read the DNA template and synthesize a complementary mRNA strand.
What is the process of forming RNA from DNA?
Transcription is the process of forming RNA from DNA. During transcription, enzymes read one strand of the DNA double helix and synthesize a complementary RNA molecule. This RNA molecule then undergoes processing and modification to become mature RNA.
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.
What new product is formed at the DNA strand?
RNA does, in contrast to DNA, form short double strand structures on itself, thereby forming so called stem and loop structures.
