25
Branch of biology concerned with the study of genes, genetic variation, and HEREDITY in organisms.
Genetics
26
The large-scale study of groups of genes. These groups can be all the genes of an organism, or multiple organisms.
Genomics
27
full complement of genetic material in an organism
genome
28
involves studies that are conducted at the level of the genome.
genomics
29
Nitrogenous bases
Purine (Adenine and Guanine) | Pyrimidine (Cytosine and Thymine
30
the backbone of the DNA strand is made from alternating
phosphate and sugar groups.
31
A heterocyclic aromatic organic compound that consists of two rings in their structure.
purines
32
water-soluble.
purines
33
They are the most widely occurring nitrogen-containing heterocycles in nature
purines
34
Is an aromatic heterocyclic organic compound similar to pyridine.
pyrimidines
35
It contains only a six membered nitrogen containing a single ring.
pyrimidines
36
In RNA the thymine is replaced by ____
uracil
37
contain a 6 membered nitrogen containing ring fused to an imidazole ring : 2 rings
Purines (adenine and guanine)
38
contain only a 6 membered nitrogen containing ring ; single Ring
Pyrimidines (cytosine and uracil)
39
The sugar in DNA is 2-deoxyribose (2 = Position/Location where it is attached), which is a
pentose (five-carbon) sugar.
40
The sugars are joined together by phosphate groups that form _________
phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings.
41
being used to distinguish these carbon atoms from those of the base to which the deoxyribose forms a glycosidic bond.
prime symbol
42
include transforming microorganisms such as bacteria or yeast, or insect mammalian cells with a gene coding for a useful protein.
Industrial applications
43
to create genetically-modified crops or genetically-modified organisms,
agriculture
44
four main points of Genetic applications:
Taxonomy Agriculture Medicine Evolution
45
Chromosome number helps in classification of plants.
taxonomy
46
genus Triticum to which wheat belongs has been classified into three groups, viz.,
diploid, tetrapod and hexaploid.
47
suggests primitive or advanced features of an organism
Karyotype
48
A karyotype with large differences between the smallest and the largest chromosome of the set is known as
asymmetric karyotype.
49
The degree of chromosome homology is studied from chromosome pairing during
meiosis
50
In taxonomy,higher the homology,
closer is the relationship between the two species.
51
Milk production in cows and buffaloes, meat production in sheep, goats and pigs and egg production capacity in poultry have been significantly improved through the application of genetic principles.
agriculture
52
Detection of Hereditary Diseases
medicine
53
Selection has to be practiced by 3 methods in evolution
Polyploidy, Introgression, and Mutagenesis
54
Natural and artificial selections have been responsible for the evolution of various crop plants.
Evolution
55
have been evolved through the application of genetic principles.
triticale
56
are brought on by environmental factors;
polygenic
57
involves evaluating the effectiveness and safety of drugs on the basis of information from an individual’s genome sequence.
Pharmacogenomics
58
can be used to prescribe medications that will be most effective and least toxic on an individual level.
Personal genome sequence information
59
study of the collective genomes of multiple species that grow and interact in an environmental niche, is often a better way to study microorganisms rather than pure culture.
Metagenomics
60
used to create new biofuels.
Microbial genomics
61
has been extensively studied for its use in fermenting ethanol fuels.
Pichia
62
have been used in forensic analysis
genetic markers
63
Like in 2001 when the FBI used microbial genomics to determine a specific strain of ___that was found in several pieces of mail.
anthrax
64
investigates how proteins affect and are affected by cell processes or the external environment.
Proteomics
65
Within an individual organism, the ____ is constant, but the___ varies and is dynamic.
genome ; proteome
66
are being used to analyze each type of cancer.
Different biomarkers and protein signatures
67
Medical technologists were not on the ____ side but more on the ____ side
proteomics ; diagnostic
68
Individuals have bigger chances in survival.
Stages 1 & 2
69
Has a lot of compilation.
Stages 3 & 4
