Explain how DNA replication takes place?
An enzyme unzips a DNA stand and a separate strand without base pairs come sup and matches it with the proper ones (A-U)( C-G) making RNA which goes to a ribosome outside the nucleus, makes a protein, makes a new strand of DNA and the other strand re zips with the new DNA strand.
What is the importance of the base pairing in DNA?
A mismatched base would mean a mutation of the genetic code for the RNA strand. The wrong amino acid would be produced and then the wrong protein. This would result in a defect or maybe a disease or death depending on how many other normal cells are present.
What is the role of formaldehyde and formamide in RNA gel electrophoresis?
Denatures the RNA
What is the difference between an amino acid and RNA?
RNA is a polymer of ribonucleic acids. Amino acids are the monomers of proteins.
During transcription the genetic information is rewritten as a molecule of?
During transcription, the genetic information is rewritten as a molecule of
What molecule builds the new strand of RNA during transcription?
RNA polymerase builds the new strand of RNA during transcription. It catalyzes the formation of phosphodiester bonds between nucleotides to create the complementary RNA strand based on the DNA template strand.
What is the replacement for thymine in an RNA strand?
The replacement for thymine in an RNA strand is uracil.
Is RNA composed of one strand?
Yes, RNA is composed of a single strand of nucleotides.
What is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA?
RNA polymerase is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA during transcription.
What strand of DNA does RNA polymerase use during transcription?
During transcription, RNA polymerase uses the template strand of DNA to create a complementary RNA strand.
What enzyeme helps a cell to make a strand of rna?
RNA polymerase is the enzyme responsible for synthesizing RNA strands during transcription in a cell. It reads the DNA template strand and adds complementary RNA nucleotides to form an RNA strand.
Is transcription the manufacture of a strand of RNA complementary to a strand of DNA?
Yes, that's correct. Transcription is the process by which the genetic information in a segment of DNA is used to create a complementary RNA strand. This RNA molecule can then be used to direct the synthesis of proteins in a cell.
Why is RNA needed to create proteins?
RNA is a single-stranded structure that is copied from an unzipped DNA strand identically, this is called transcription. The RNA strand contains the complementary base pairs for the DNA sequence. The DNA strand has sections that code for specific proteins, so when the RNA strand is created from the DNA, the RNA strand is then able to recreate the sequence that codes for the proteins. The RNA strand leaves the nucleus, via a nuclear pore, and enters the cytoplasm. In the cytoplasm the RNA strand binds to two Ribosomal subunits, and translation is carried out, producing proteins.
What enzyme is responsible for decodingthe DNA strand into an mRNA?
The enzyme responsible for decoding the DNA strand into an mRNA is called RNA polymerase. It catalyzes the synthesis of mRNA during transcription by matching complementary RNA nucleotides with the DNA template strand.
Is influenza single strand or double strand RNA?
It is single stranded RNA. Importantly, it is also a segmented genome that allows it to have large genetic diversity.
What is the process by which a molecule of DNA is copied into a strand of RNA occurs where?
The process by which a molecule of DNA is copied into a strand of RNA is called transcription. It occurs in the nucleus of a cell and involves the enzyme RNA polymerase, which reads one strand of the DNA molecule and synthesizes a complementary RNA strand. This new RNA molecule then serves as a template for protein synthesis.
In which direction does RNA polymerase read a DNA strand?
The correct answer is: RNA is synthesized by RNA polymerase that reads one strand of DNA. RNA polymerase reads DNA 3' to 5'. When RNA is made, it is made 5' to 3'. Most polymerases have the 3' to 5' "reading" activity. The created RNA strand is identical to the coding strand of DNA, which is also in the orientation of 5' to 3'.
