Molecular Structure of DNA
A monomer (building block, basic structural unit) within a DNA polymer.
What is a nucelotide?
What is a chromosome?
The prokaryotic mechanism for controlling gene expression.
What is Operon?
What is Gene Expression?
Cellular process during which DNA is used as a template for the production of RNA.
What is Transcription?
These are the four nucleotide subunits that make up DNA.
What is Adenine, Guanine, Cytosine and Thymine?
The cells of all body tissues in a sexually reproducing organism except those used to produce new organisms.
What is Somatic Cells?
Cells do not produce cAMP without this enzyme.
What is Adenylate cyclase?
Binding sites for activators and repressors.
What is Enhancer and Silencer elements?
Unit of three nucleotides bases in mRNA that specifies an amino acid.
What is the Genetic Code?
Linear polynucleotide strands created by phosphodiester bonds. Two of these strands are held to each by forming hydrogen bonds between their nitrogenous bases.
What is a Double Helix?
The stages of the Cell Cycle.
What is G1, S, G2 and M phase?
The sensitivity based on the usage of gene segments.
What is a Leader sequence?
Attaches a methyl group to a cytosine.
What is DNA methyltransferase?
The types of point mutations.
What is Base Substitution, Nonsense and Frameshift?
This year, DNA was determined to be the universal inheritance material.
What is 1952?
The 5 substages of Prophase.
What is Leptonema, Zygonema, Pachynema, Diplonema and Diakinesis?
What is cAMP-CAP?
Function of transcription factors are regulated by these three mechanisms.
What is Protein-Protein interactions, Small Effector Molecules and Covalent Modifications?
The three initiation factors of Translation?
What is mRNA attached by a ribosome unit, tRNA carrying MET attaches to mRNA, next subunit of ribosomes attaches?
These two men connected the pieces of information together to propose an accurate model of the DNA structure.
What is Watson & Crick?
Stages of cell division (Mitosis/Meiosis) that require the dissolution of Cohesin proteins.
What is Anaphase of Mitosis, Diplonema, Anaphase I and II of Meiosis?
Discovered that even high levels of tryptophan, transcription is always initiated, not always completed.
What is Yanofsky & Bertrand?
Cannot be translated. Double stranded fragments form due to base complementarity.
What is RNA interference?
Missense mutation. Chromosome #4. 1/15,000 are affected, autosomal dominant but 75% are new mutations. Homozygous dominant individuals do not thrive.
What is Achondroplasia (Dwarfism)?
