Document Summary
Two strips of nucleotides paired together double helix. Dna polymerase moves only in one direction, helps in replication. Source of our genetic information; genetic information telling the cell how to make a protein. Area on the strand of dna that holds information. Gene is a word; chromosomes is like a chapter of a book. Gene contains info how to make a protein. Info is take to make a rna transcript of that gene. Dna stores the information that the cell needs to produce proteins. One strand has to match with another strand to build in the double helix. A and t comes together with 2 hydrogen between them. C and g comes together with 3 hydrogen between them are more tightly bonded together. Transcription produces an rna molecule that"s complementary to dna. Dna is storing information; rna is carrying the information. Rna; messenger rns, ribosomal rna and transfer rna. Transcription occurs in the nucleus because dna cannot leave the cell.
