RNA is accociated with?
RNA (Ribonucleic Acid)...this is the messenger of the DNA (Deoxyribonucleic Acid) The RNA carries directions from the DNA to the Ribosomes that tell the Ribosomes what protein to make and how to do it. RNA reads the blueprint (DNA)
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.
What does the name Deoxyribonucleaicacid tell you about the chemical make up of DNA that is different from RNA?
An oxygen is missing from the DNA compared to the RNA -- so it has been de-oxygenated.
What are two types of nucleic acid found the cell?
Deoxy-ribonucleic acid (DNA) and ribonucleic acid (RNA)
What is the name of the nucleotides have no DNA and no RNA?
Nucleotides do not have DNA or RNA. DNA and RNA are composed of nucleotides.
What is the function of primers?
RNA primers are used to initiate the DNA replication at the template strand. DNA molecules require a free 3' OH, to which it could add the nucleotides. This free 3' OH is provided by the RNA primer. So prior to the synthesis of DNA a short fragment of RNA is synthesized that is later excised and filled with DNA molecules.
What is RNA polymerase and tell its functions?
RNA polymerase is an enzyme that produces RNA. In cells, RNAP is needed for constructing RNA chains from DNA genes as etc
Did RNA exist before DNA?
There are many reasons why scientists think RNA came before DNA. RNA is found in viruses and some bacteria which were likely around before more complex organisms.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
A major difference in RNA as compared to DNA is?
RNA can move and DNA cant. DNA has a double helix strand and RNA is a single strand.
What is the substance in RNA but not DNA?
An uracil base is in RNA but not in DNA
Are DNA and RNA carbohydrates?
Yes, DNA and RNA have different sugar . DNA contains deoxyribose sugar whereas RNA consists of ribose sugar, which are completely different from each other.
