Biology Unit 6: DNA

________ is an enzyme that starts DNA Replication by breaking away the two DNA strands like a zipper.

________ connect to the deoxyribose or ribose(RNA). It consists of adenine(A), guanine(G), thymine(T), cytosine(C).

________ are the bonded sets of nucleotides in DNA.

________ is located in the chromatin of the nucleus.

________ is synthesized in the nucleolus, but is sent to the ribosomes.

DNA is short for ________.

________ is the backbone of the double helix shape of DNA.

RNA is short for ________.

________ is the backbone of the single strand shape of RNA.

________ bond to pyrimidines.

________ build specific proteins based on the genetic sequence.

In the leading strand, ______ is an enzyme that synthesizes RNA fragments onto the DNA, called primers. In the lagging strand, ________ creates many primers that would be connected by ozakaki fragments.

________ are the pieces of DNA between primers in the lagging strand.

______ are RNA fragments used to let the DNA polymerase start making the DNA. In the leading strand, ______ are used to start the constant synthesis of the new DNA strand. In the lagging strand, ________ are connected by ozakaki fragments.

In the leading strand, ______ attaaches free nucleotides to the DNA strand constantly in one direction. In the lagging strand, ________ attaches free nucleotides to the DNA from one primer to another, which creates ozakaki fragments.

In the leading strand, ________ removes the RNA primers, which would be replaced by DNA by DNA polymerase

In the lagging strand, ________ connects ozakaki fragments.
