Ribosomes
What happens in translation?
Building of proteins
What replaces thymine in RNA?
Uracil
Functions of mRNA
Acts as intermediary between DNA and ribosomes and translated into protein by ribosomes
Functions of tRNA
Delivery system of amino acids to ribosomes as they synthesize proteins
What is ribosomal RNA OR rRNA
Binds with proteins to form ribosomes
Role of RNA
Assist in protein synthesis and controls gene expressin
Antiparallelism
Opposing orientation of the two nucleotide chains in DNA
How do hisotones and nucleosomes interact with DNA
DNA coils around hisotones(proteins), resembles beads that are called a nucleosome
What are hisotones?
Proteins
What does it mean to say that replication is semi conservative?
Each new DNA double helix conserves half of the original
Primase
Adds short primer to template strand
Binding proteins
Stabilizes separate DNA strands
