During transcription an RNA molecule does what?
During transcription an RNA Molecule is formed inside the nucleus. The DNA is too large to leave the nucleus and participates directly in the cytoplasmic protein synthesis. It is necessary to make a small copy of Messenger RNA that will migrate out of the nuclear pore in to the cytoplasm.
Why both strands of DNA are not copied during transcription?
since rna is single stranded........it only needs one complementary strand......!
What strand of DNA is used to make a complementary copy or to make a complementary mRNA molecule-?
The strand is called the parental strand. the gene being copied would depend on which protein is needed.
What has an anticodon region?
Anticodons are a sequence of three adjacent nucleotides located on one end of transfer RNA. It bounds to the complementary coding triplet of nucleotides in messenger RNA during translation phase of protein synthesis.
What attaches free nucleotides to the growing DNA strand?
During DNA replication, DNA polymerase binds free DNA nucleotides to an unzipped DNA strand. During transcription, RNA polymerase binds free RNA nucleotides to the unzipped anti-sense DNA strand.
Which nitrogen base is the complementary base for adenine during transcription?
Thymine is the complementary base for adenine during DNA transcription. During RNA transcription, however, uracil is the complementary base for adenine.
What connects Rna nucleotides to dNA during transcription?
RNA polymerase
Is RNA made from 1 strands of DNA?
No, RNA is synthesized from a single strand of DNA through a process called transcription. During transcription, the DNA helix unwinds, and an enzyme called RNA polymerase builds a complementary RNA molecule by pairing RNA nucleotides with the DNA template strand. This resulting single-stranded RNA molecule can then go on to perform various functions in the cell.
Which produced during translation ribosomal RNA transfer RNA proteins DNA?
copying part of the nucleotide sequence of DNA into a complementary sequence in RNA is called TRANSCRIPTION
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.
During what process are rna molecules produced by copying part of the nucleotide sequence of dna into a complementary sequence in rna?
Transcription.
What is one role that triphosphate deoxyribonucleotides play in a cell?
Triphosphate deoxyribonucleotides form hydrogen bonds with their complements in a DNA parent strand during transcription of the leading strand of DNA. Example Adenine nucleotides bind to thymine nucleotides Guanine nucleotides bind to Cytosine nucleotides

What happen during the transcription process of DNA?
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both RNA and DNA are nucleic acids, which use base pairs of nucleotides as acomplementary language that can be converted back and forth from DNA to RNA by the action of the correctenzymes. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript. As opposed to DNA replication, transcription results in an RNA complement that includes the nucleotide uracil (U) in all instances wherethymine (T) would have occurred in a DNA complement. Also unlike DNA replication where DNA is synthesized, transcription does not involve an RNA primer to initiate RNA synthesis.Transcription can be reduced to the following steps, each moving like a wave along the DNA.One or more sigma factors initiate transcription of a gene by enabling binding of RNA polymerase topromoter DNA.RNA polymerase moves a transcription bubble, like the slider of a zipper, which splits the double helix DNA molecule into two strands of unpaired DNA nucleotides, by breaking the hydrogen bonds between complementary DNA nucleotides.RNA polymerase adds matching RNA nucleotides that are paired with complementary DNA nucleotides of one DNA strand.RNA sugar-phosphate backbone forms with assistance from RNA polymerase to form an RNA strand.Hydrogen bonds of the untwisted RNA + DNA helix break, freeing the newly synthesized RNA strand.If the cell has a nucleus, the RNA may be further processed (with the addition of a 3'UTR poly-A tail and a 5'UTR cap) and exits to the cytoplasm through the nuclear pore complex.
What strand of DNA is used to make a complementary copy or to make a complementary mRNA molecule-?
The strand is called the parental strand. the gene being copied would depend on which protein is needed.
What happens During replication DNA .?
During DNA replication the following occurs: 1) An enzyme called helicase separates the DNA strands (the space where they separate is called the replication fork). 2) DNA polymerase adds complementary nucleotides to the separated strand of DNA. 3) The DNA polymerase enzyme finishes adding nucleotides and there are two identical DNA molecules.
