• Department Network Administrator

DNA is a very large molecule made up of a long chain of sub-units called

• phosphate groups

• organic bases

• nucleotides

• deoxyribose

What base pair matches with Adenine in DNA

What base pair matches with Guanine in RNA?

What makes up a double helix?

• oxygen-phosphate chain connected to bases

• paired bases connected to a sugar-phosphate chain

• triplet bases connected to a sugar-phosphate chain

• ribose connected to deoxyribose

_____ base groups control the production of a particular amino acid in the ______ of a cell

• double, nucleus

• triplet, nucleus

• double, cytoplasm

• triplet, cytoplasm

The DNA controls which _____ are made up and these determine what reactions take place

A condition caused by mutations in one or more genes is called

• replication

• genetic disorder

• somatic mutation

• hereditary mutation

What is also known as a germ line mutation inherited from a parent and exist in every cells in the body

• hereditary mutation

• somatic mutation

• silent mutation

• missense mutation

What is a silent mutation

• not changing an amino acid, but in some cases can still have a phenotypic effect

• change in one DNA base pair, leads to changing in amino acid, so another proteins may be made

• change in DNA base pair, so, changed DNA send a signal to deter making a protein that leads to produce shorter protein

• addition or loss of DNA bases changes a gene's reading frame
