DNA Structure
In DNA, Cytosine always bonds with _____.
What is Guanine?
This is the site of DNA replication.
What is the nucleus?
During replication the unzipping and rebuilding of DNA molecules is completed by these types of specialized proteins.
What are enzymes?
Transcription is part one of this process and happens in this part of the cell.
What is the nucleus?
The rungs of the DNA ladder are made of these.
What are nitrogenous bases?
This is the SHAPE DNA is described as.
What is double helix?
Overall goal of DNA Replication
What is to produce 2 identical strands of DNA?
DNA replication occurs for these two reasons.
What is to repair damaged DNA or to pass on genes to offspring?
Translation occurs in this part of the cell.
What is the cytoplasm?
The name of a single piece of DNA that codes for a specific protein is called a _______.
What is gene?
These two things make up the "backbone" of DNA.
What is phosphate and sugar (deoxyribose)?
The enzyme that rebuilds DNA.
What is DNA Polymerase?
This enzyme breaks the bonds between the bases and unzips the DNA molecules.
What is DNA helicase?
This cell structure is responsible for reading the mRNA molecule and attaching amino acids in a chain.
What is the ribosome?
Another name for a protein
What is an amino acid chain?
This is the name of the building blocks of DNA (the monomer).
What is nucleotide?
During DNA replication, the complementary DNA strand for ACGTCC would be:
What is TGCAGG?
This type of mistake can result in a new gene being written.
What is a mutation?
The four nitrogenous bases in mRNA are Adenine, Thymine, Cytosine, and _________.
What is Uracil?
If a DNA strand had 40% Cytosine, how much Adenine would it have?
What is 10%?
The 3 parts of a nucleotide.
What is phosphate, sugar, nitrogenous base.
When DNA replicates half the molecule is original and the other half is a newly written _____________ strand.
What is complimentary?
Because half of the original DNA strand is still present in the new strand, replication is often called this.
What is semi-conservative?
The sequence of the nitrogenous bases in the DNA and mRNA will determine the resulting proteins ________, which will then determine the proteins __________.
What is shape and function?
What does DNA actually stand for?
What is Deoxyribonucleic Acid?
