Principles of Biomedical Sciences Flashcards
What does Adenine mean?
A component of nucleic acids, energy-carrying molecules such as ATP, and certain coenzymes. Chemically, it is a purine base.
What is a Chromosome?
Any of the usually linear bodies in the cell nucleus that contain the genetic material.
What is Cytosine?
A component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically, it is a pyrimidine base.
What is DNA?
A double-stranded, found in nucleus of cell
What is Gel Electrophoresis?
The separation of nucleic acids or proteins, on the basis of their size and electrical charge, by measuring their rate of movement through an electrical field in a gel.
What is Gene?
A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses).
What is Guanine?
A component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically, it is a purine base.
What is Helix?
Something spiral in form.
What is a model?
simplified version of something complex used, for example, to analyze and solve problems or make predictions.
What is Nucleotide?
It is a phosphate, sugar, and base that is connected together
What is Enzyme?
A degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA
What is RLFPs?
Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes).
What is Thymine?
A component of nucleic acid that carries hereditary information in DNA in cells. Chemically, it is a pyrimidine base.
