DNA
What is DNA?
Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for development.
What is the last step in DNA replication called?
Termination
what sugar is used for RNA?
ribose
What occurs first in transcription?
RNA polymerase is the main transcription enzyme
Which one of the following does not play a role in translation?
DNA
Is DNA one helix or double?
double helix
Where does DNA replication occur in a cell?
in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.
What is RNA used for?
in one form or another, touches nearly everything in a cell
What enzyme is used in transcription?
RNA polymerase
What is created in translation?
What holds one strand against the other in the double helix?
Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups
What is the first step in DNA replication?
you will need to unzip the DNA
What does RNA look like?
RNA is typically single-stranded and comes in various forms.
What are the five steps of transcription?
pre-initiation, initiation, promoter clearance, elongation, and termination:
What are the 3 stages of translation?
initiation, elongation, and termination.
What information is coded into DNA?
Genetic code
What pieces are needed for DNA replication?
requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
What is RNA?
ribonucleic acid, a nucleic acid present in all living cells
what pieces are needed for transcription?
RNA polymerase binds to a sequence
whats is translation?
is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis.
When do cells duplicate their DNA?
when they decide they need to divide
what is DNA REPLICATION?
DNA replication is the process by which DNA makes a copy of itself during cell division.
Where is RNA located?
nucleus of the cell
what is transcription?
DNA replication is the process by which DNA makes a copy of itself during cell division.
What are the 5 steps of translation?
text to be translated, Initial translation, Review the accuracy of the translation, Take a break. Refine translation wording.
