|
Operon |
unit of genetic function common and bacteria and phages, consisting of coordinately regulated clusters of genes with related functions |
|
|
Pedigree |
A diagram that shows the occurrence of a genetic trait in several generations of a family |
|
|
DNA ligase |
Enzyme that chemically links DNA fragments together |
|
|
Haplotype mapping |
Focuses on identifying the slight variations in the human genome that affects a person, success, ability to disease and responses to environmental factors such as microbes toxins and drugs Human genome project: an attempt to identify all the genes in the human genome |
|
|
Transcription |
The transfer of genetic information from DNA into mRNA molecule takes place in the nucleus. Single DNA strand serves as a template for creation of complementary mRNA copy. Attaches RNA polymerase enzyme to a DNA molecule. Creates messenger mRNA molecule. |
|
|
Cytogenetic |
The field of genetics that involves the microscopic examination of chromosomes |
|
|
Structural genes are responsible for? |
Coding the amino acid sequence of a polypeptide chain |
|
|
Mitosis vs meiosis |
Mitosis: one cell division, replicates DNA to form two identical cells, resulting cells should have identical cells, resulting cells should have identical sets of 23 pairs of chromosomes. Meiosis: two divisions, forming for genetically different cells, meiosis, one and two, forms reproductive cells with a single set of 23 chromosomes, only happens in sex cells |
|
|
Induction |
An important process by which gene expression is increased |
|
|
Mendel law |
The theory of genes as units of inheritance, discovered allele pairs and recessive dominant traits. Set basic rules on genetic heritage Explains different possibilities, (alleles) that exists for a specific position,(locus) of a gene. |
|
|
RNA interference technology |
Gene silencing Technology that prevents cells from making a specific protein that contributes to disease Based on natural processes cells used to regulate protein expression Most common form of RNAi employs small interfering RNAs (siRNAs) |
|
|
RNA messenger |
RNA that copies of coded message from DNA and the nucleus and carries the message into the cytoplasm |
|
|
Post-translational processing |
Regulate protein activity through processing, folding, joining and making chemical modifications |
|
|
Gene therapy |
The insertion of working copies of a gene into the cells of person with a genetic disorder, in an attempt to correct the disorder |
