WGU Biochem C785: Unit 4 DNA and RNA
DNA (deoxyribonucleic acid) (ANS - An organisms genetic material found in the nucleus of a cell
Double stranded helical nucleic acid molecule consisting of nucleotide monomers with deoxyribose sugar and nitrogenous bases (A, C, G, T) capable of replicating
Which nucleotides/bases are used in DNA?
(ANS –
A - Adenine C - Cystine G - Guanine T - Thymine
RNA (ribonucleic acid) (ANS - A nucleic acid consisting of nucleotide monomers with a ribose sugar and nitrogenous bases (A, C, G, U)
Usually single stranded
Functions in protein synthesis, gene regulation, and as the genome of some viruses
Central Dogma (ANS - DNA -> RNA -> Protein
DNA -> Transcription ->mRNA -> Translation -> Protein
The process by which the instructions in DNA are converted into a functional product
The flow of genetic information from DNA to RNA protein
- / 2
Which nucleotides/bases are used in RNA?(ANS A - Adenine C - Cystine G - Guanine U - Uracil
Which nucleotides/bases pair together to form DNA?
(ANS –
A - T C - G
Which nucleotides/bases pair together to form RNA?
(ANS –
A - U C - G
Genes (ANS - A segment of a DNA molecule that information or directions on how to build a protein
Gene Expression
(ANS –
When a gene in DNA is "turned on" or used to make the protein is specifies
Includes 2 Stages: Transcription and Translation
Nucleotides (ANS - Basic units of DNA molecule, composed of a sugar, a phosphate, and one of 4 DNA bases
Antiparallel (ANS - The opposite arrangement of the sugar-phosphate backbones in a DNA double helix (5'-3', 3'-5')
