What are the characteristics of the tertiary level of proteins?
three dimensional shape of proteins
DNA is often coiled around proteins called what?
DNA is often coiled around proteins called histones.
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.
Transcription always starts at a region called what?
Transcription always starts at a region called the promoter.
True or False: RNA is a single sided stranded.
True. DNA is double stranded.
What is Transcription?
Transcription: DNA ---> mRNA
What are the characteristics of quaternary level of proteins?
two or more chains of polypeptides
What are the characteristics of the secondary level of proteins?
α-helix and the ß-sheet.
What is an Okazaki Fragment?
are short sequences of DNA nucleotides
What does DNA helicase do?
DNA Helicase is an (enzyme) unwinds the DNA.
One of the 2 strands of DNA is used as a what strand to create a new strand of mRNA?
Template Strand
What is RNA Polymerase?
RNA Polymerase is an enzyme that makes/synthesizes mRNA in the same manner that DNA is duplicated.
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 a codon?
Each 3 bases on mRNA are called codons. Each codon codes for 1 amino acid.
