What else can I help you with?
If a strand of DNA has the sequence aagctc transcription will result in?
If a strand of DNA has the sequence aagctc, transcription will result in a mRNA molecule with the complementary sequence uucgag. Transcription is the process of creating a mRNA molecule using DNA as a template.
How many strands does mRNA have?
mRNA typically consists of a single strand of nucleotides. It serves as a temporary copy of the genetic information in DNA and carries this information from the nucleus to the ribosomes for protein synthesis.
How many strands of mRNA are made during the process of transcription?
A single mRNA strand is typically produced but a single strand can make many many copies of the protein encoded on the molecule.
What attaches to the mRNA strand as translation begins?
After the two ribosomal subunits attach to a strand of mRNA, a tRNA molecule with the amino acid methionine attaches to the start codon, AUG.
What is the shape of mRNA?
mRNA is most commonly linear but can form a duplex double strand just like DNA.

How is dna made into mRNA?
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.

mRNA typically consists of a single strand of nucleotides. It serves as a temporary copy of the genetic information in DNA and carries this information from the nucleus to the ribosomes for protein synthesis.
What strand of DNA is use to make a complementary copy or to make a complementary mRNA molecule?
The template strand is used to make a complementary copy. This is a type of DNA strand.
How many strands of DNA are used for transcription?
No, just one strand, the coding strand is used to create a mRNA molecule in the process of transcription.
How many strands of mRNA are made during the process of transcription?
A single mRNA strand is typically produced but a single strand can make many many copies of the protein encoded on the molecule.
What attaches to the mRNA strand as translation begins?
After the two ribosomal subunits attach to a strand of mRNA, a tRNA molecule with the amino acid methionine attaches to the start codon, AUG.
What molecule copies the DNA coding strand and leaves the nucleus?
mRNA copies the information.Process is called transcription.
What transcribes mRNA?
DNA transcribes mRNA through a process called transcription. The enzyme RNA polymerase synthesizes the mRNA by reading the DNA template strand and creating a complementary RNA strand. This mRNA molecule carries the genetic information from the DNA to be translated into proteins in the cell.
What are the ribosomes linked togetherby a single strand of mRNA called?
Ribosomes linked together by a single strand of mRNA are called polysomes or polyribosomes. These structures allow multiple ribosomes to simultaneously translate the same mRNA molecule, increasing the efficiency of protein synthesis.
What is the step of protein synthesis that occurs in the nucleus?
The step of protein synthesis that occurs in the nucleus is transcription. Transcription is the process of copying the genetic code from DNA into RNA. The RNA molecule that is produced during transcription is called messenger RNA (mRNA). mRNA then travels to the cytoplasm, where it is translated into a protein. In transcription, the DNA double helix opens up at a specific location called the promoter. A protein called RNA polymerase binds to the promoter and begins to move along the DNA strand, unzipping the helix as it goes. RNA polymerase then uses the exposed DNA strand as a template to synthesize a complementary RNA strand. This RNA strand is the mRNA molecule. Once the mRNA molecule is complete, it separates from the DNA and travels to the cytoplasm. In the cytoplasm, the mRNA molecule binds to a ribosome. The ribosome then reads the mRNA molecule and uses the information to assemble a protein molecule. The protein molecule is then released from the ribosome and can go on to perform its function in the cell. Here are the steps of transcription in detail: Initiation: RNA polymerase binds to the promoter region of DNA. Elongation: RNA polymerase moves along the DNA strand, unzipping the helix and synthesizing a complementary RNA strand. Termination: RNA polymerase reaches a termination sequence in the DNA and stops synthesizing RNA. The mRNA molecule that is produced during transcription is a single-stranded molecule that contains the same information as the original DNA strand. However, the mRNA molecule is modified in a few ways. First, the 5' end of the mRNA molecule is capped with a group of nucleotides called a 5' cap. The 5' cap helps to protect the mRNA molecule from degradation and helps it to bind to the ribosome. Second, the 3' end of the mRNA molecule is polyadenylated, which means that it is added to a long chain of adenine nucleotides. The polyadenylation tail helps to stabilize the mRNA molecule and helps it to be transported to the cytoplasm. Transcription is a complex process that is essential for protein synthesis. It is the first step in the process of converting genetic information into a functional protein molecule.

mRNA is most commonly linear but can form a duplex double strand just like DNA.
