RNA Polymerase is an enzyme that makes/synthesizes mRNA in the same manner that DNA is duplicated.
What is a codon?
Each 3 bases on mRNA are called codons. Each codon codes for 1 amino acid.
Where does Transcription occur?
Transcription happens in the nucleus
Transcription always starts at a region called what?
Transcription always starts at a region called the promoter.
What are segments of nucleotides located on the chromosomes that give specific instructions for a single trait?
Genes are segments of nucleotides located on the chromosomes that give specific instructions for a single trait
DNA is coiled into strands, called what, which are found in the nucleus of Eukaryotes.
DNA is coiled into strands, called chromosomes, which are found in the nucleus of Eukaryotes.
Where does Translation occur?
Translation happens in the ribosome.
What are the characteristics of quaternary level of proteins?
two or more chains of polypeptides
What is Translation?
Translation: mRNA ---> Protein
What is the building block of a protein?
Amino acids are the building blocks of protein
What is Transcription?
Transcription: DNA ---> mRNA
WHy is DNA Replication called semi-conservative?
because one half of the original strand is always saved, or “conserved.”
What are the characteristics of the primary level of proteins?
arrangement of amino acids
What does DNA helicase do?
DNA Helicase is an (enzyme) unwinds the DNA.
Translation requires which enzyme?
RNA Polymerase
DNA is often coiled around proteins called what?
DNA is often coiled around proteins called histones.
In DNAearth, C is married to G and in RNAland C is also married to G. A is married to T in DNAearth, but who is A married to in RNAland?
A is married to U in RNAland
What is DNA Polymerase?
adds the complementary nucleotides and binds the sugars and phosphates. DNA polymerase travels from the 3’ to the 5’ end. The DNA is called the template strand.
True or False: RNA is a single sided stranded.
True. DNA is double stranded.
What is Messenger RNA (mRNA)?
mRNA: It makes a mirror copy of a gene on the DNA strand in the nucleus.
What are the characteristics of the secondary level of proteins?
α-helix and the ß-sheet.
