The nucleus stores DNA and is where RNA transcription occurs.
RNA polymerase is the enzyme responsible for binding to DNA and synthesizing a complementary RNA strand during transcription.
Transcription is the process in the cell nucleus where enzymes synthesize an RNA copy of a DNA gene. This process involves the enzyme RNA polymerase reading the DNA template and constructing the complementary RNA molecule. The resulting RNA transcript serves as a blueprint for protein synthesis.
Generally there is one mRNA transcript made from each gene. There are exceptions to this.
The key steps of transcription are initiation, elongation, and termination. During initiation, RNA polymerase binds to the promoter region of DNA. Then, during elongation, the RNA polymerase synthesizes an RNA copy of the DNA template. Finally, termination signals the end of transcription and release of the RNA transcript.
RNA is actually a single stranded copy of DNA composed of ribonucleic acids, hence the name RNA. Genomic DNA is read by an enzyme called RNA polymerase which uses DNA as a template to make a corresponding RNA copy. The RNA transcript is recognized by ribosomes and is used as a guide to assemble amino acids into long chains called polypeptides or proteins. The letters (or bases) of the DNA corresponds exactly to the letters made in the RNA. A-->U C--> G
Nucleus
All RNA is single-stranded. Messenger RNA (mRNA), however, is a transcript of DNA.
RNA polymerase is the enzyme responsible for binding to DNA and synthesizing a complementary RNA strand during transcription.
The organelle that is made up of DNA and RNA in the nucleus is called the nucleolus. It is involved in the production of ribosomes, which are essential for protein synthesis in the cell.
DNA makes RNA, & RNA makes polypeptides (proteins)
RNA polymerase reads the DNA template and synthesizes a complementary RNA strand by linking together RNA nucleotides according to the base pairing rules. RNA polymerase moves along the DNA strand in the 3' to 5' direction, synthesizing the RNA transcript in the 5' to 3' direction.
Largest organelle in the nucleus; contains DNA, RNA, and proteins.
Transcription is the process in the cell nucleus where enzymes synthesize an RNA copy of a DNA gene. This process involves the enzyme RNA polymerase reading the DNA template and constructing the complementary RNA molecule. The resulting RNA transcript serves as a blueprint for protein synthesis.
transcription:"the first step in protein synthesis, a sequence of nucleotide bases becomes exposed in an unwound region of a DNA strand. That sequence acts as a template upon which a single strand of RNA - a transcript - is synthesized from free nucleotides."The synthesis of an RNA molecule from the DNA template strand is called transcription.
RNA hairpin turns contain a termination signal that is recognized by specific proteins involved in termination of transcription. When RNA polymerase encounters this signal, it triggers the release of the RNA transcript and dissociation of the RNA polymerase from the DNA template, marking the end of transcription.
Generally there is one mRNA transcript made from each gene. There are exceptions to this.
mRNA is a type of RNA that carries the genetic information from DNA out of the nucleus to the ribosomes for protein synthesis. A DNA-RNA hybrid is a transient complex formed by the base pairing between a DNA strand and an RNA strand. mRNA is a single-stranded transcript of a specific gene, while a DNA-RNA hybrid involves temporary hydrogen bonding between complementary regions of DNA and RNA molecules.
