What produces an mRNA copy of DNA?
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
What is the name of the enzyme that creates the mRNA copy from DNA quizlet?
RNA polymerase (the enzyme) splits apart strands of DNA, making an mRNA molecule by adding RNA nucleotides one at a time.
What enzyme is involved in translation?
ribosome
Translation is catalyzed by a large enzyme called a ribosome, which contains proteins and ribosomal RNA (rRNA). Translation also involves specific RNA molecules called transfer RNA (t-RNA) which can bind to three basepair codons on a messenger RNA (mRNA) and also carry the appropriate amino acid encoded by the codon.
What reads the mRNA quizlet?
The ribosome reads the mRNA strand, and with the help of tRNA, builds the corresponding amino acid chain. DNA does not build or synthesize a protein it encodes for; instead, DNA contains information that is copied by an enzyme to make mRNA, which leaves the nucleus and goes to the ribosome where the protein is built.
What is DNA and mRNA?
Messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
What is mRNA and DNA?
Is mRNA an enzyme?
What is the name for the process in which information in an mRNA molecule is used to generate a polypeptide made of amino acids quizlet?
Ribosomes use the sequence of codons in mRNA to assemble amino acids into polypeptide chains. The decoding of an mRNA message into a protein is a process known as translation.
What would happen to the protein of mRNA made a mistake when copying the DNA?
If a mistake occurred during a given situation in protein synthesis, for example, if the RNA polymerase doesn’t copy the DNA into a complementary strand into mRNA during transcription, then the mRNA wouldn’t exist and since the DNA is unable to leave the nucleus of the cell, the genetic code wouldn’t reach the …
What is the enzyme that makes mRNA from DNA strand?
The answer is RNA polymerase. It is an enzyme in the cell responsible for creating mRNA from the correct gene. It is similar to DNA polymerase except for it makes RNA strand instead of DNA strand. It attaches to the promoter region of a DNA helix.
How is RNA polymerase similar to DNA polymerase?
During the process of Transcription RNA Polymerase transcribes a copy of the DNA into a mRNA, utilising Uracil in place of Thymine. In function RNA Polymerase is almost similar to DNA Polymerases.
Which is strand of DNA transcribes into mRNA?
RNA polymerase (an enzyme that specifically makes mRNA) moves along the strand of DNA and joins complementary strands (in RNA, the complement to adenine is uracil instead of thymine). mRNA is produced only for the gene that is being read at that time. This process is called transcription. Which strand of DNA transcribes into mRNA?
