DNA Structure
Double helix
Which bonds are being broken during DNA replication?
Hydrogen bonds
What is a chain of amino acids called?
Polypeptide
Name the three types of RNA
tRNA
rRNA
Cells with 23 chromosomes, such as sperm and egg cells, are called these.
Gametes
What is the sugar found in DNA?
Which phase does DNA replication in the cell cycle?
S phase
What is the central dogma of genetics?
DNA -> mRNA -> Protein
RNA contains this base instead of thymine
Uracil
Body cells that are not reproductive cells are called these.
Somatic Cells
Write out the 4 nitrogen bases pairs found in DNA
Guanine
Thymine
Cytosine
New DNA strands are built by adding these building blocks after unzipping DNA
Nitrogen bases
The process that occurs in the nucleus and makes mRNA from DNA
Transcription
rRNA
Cells with two sets of chromosomes are described as this.
Diploid
What is the backbone of made of in DNA?
Phosphate and Deoxyribose
During replication, adenine pairs with this base and cytosine pairs with this base.
Thymine and guanine
The process that occurs at the ribosomes and builds proteins.
Translation
Refers to controlling whether a gene is turned on or off
Gene regulation
The type of cell division that produces gametes.
Meiosis
Which bond hold the complementary bases together?
Hydrogen bonds
Term used to refer to DNA molecule that contains one original and one new strand
Semi Conservative
This RNA carries amino acids to the ribosome
tRNA
The study of changes in gene expression that do not change the DNA sequence.
epigenetics
This process during Prophase I increases genetic variation by exchanging DNA between homologous chromosomes.
