DNA is often coiled around proteins called what?
DNA is often coiled around proteins called histones.
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.
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
What are the characteristics of the primary level of proteins?
arrangement of amino acids
What are the characteristics of the secondary level of proteins?
α-helix and the ß-sheet.
What are the characteristics of the tertiary level of proteins?
three dimensional shape of proteins
What are the characteristics of quaternary level of proteins?
two or more chains of polypeptides
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
True or False: RNA is a single sided stranded.
True. DNA is double stranded.
What is DNA Replication?
DNA copies itself.
What does DNA helicase do?
DNA Helicase is an (enzyme) unwinds the DNA.
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.
WHy is DNA Replication called semi-conservative?
because one half of the original strand is always saved, or “conserved.”
What is an Okazaki Fragment?
are short sequences of DNA nucleotides
What is Transcription?
Transcription: DNA ---> mRNA
What is Translation?
Translation: mRNA ---> Protein
