Genetic material
a gene, a part of a gene, a group of genes, or fragments of many genes, on a molecule of dna, a fragment of dna, a group of dna molecules, or fragments of many dna molecules.

Frederick Griffith accidentally discovered transformation when attempting to develop a vaccine for pneumonia.

can Transform Bacteria - Frederick Griffith, 1931
When Streptococcus pneumoniae (pneumococcus) bacteria are grown on a culture plate, some produce smooth shiny colonies (S) while others produce rough colonies (R).

Genetic material
Two different kinds of genetic material exist: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Viruses may carry DNA or RNA as their . DNA may be single- or double-stranded (ssDNA and dsDNA), and it may be circular or linear.

Genetic material

All the genetic material in the chromosomes of a particular organism; its size is generally given as its total number of base pairs.

This creates four unique chromatids
Since each chromatid is unique, the overall genetic diversity of the gametes is greatly increased

The is able to specify a large variety of proteins. The nature of the was unknown for a long time .

The genetic material of an organism consists of deoxyribonucleic acid (DNA).

The in retroviruses is in the form of RNA molecules, while the of their hosts is in the form of DNA. When a retrovirus infects a host cell, it will introduce its RNA together with some enzymes into the cell.

The genetic material found in mitochondria, the organelles that generate energy for the cell. Not inherited in the same fashion as nucleic DNA.

The first was probably RNA, not DNA.
Thomas Cech and Sidney Altman found that RNA molecules not only play a central role in protein synthesis, but also are important catalysts in modern cells.

germ plasm Genetic material that may be preserved for future agricultural, commercial, and ecological values (plant seeds or parts or animal eggs, sperm, and embryos).
germ Embryo of a cereal grain.

Exchange of genetic material between maternal and paternal chromatids during meiosis to produce recombined chromosomes. (Figure 8-18) See also recombination.

Germ line: transmitted from one generation to the next through the gametes. A germ line mutation exists in all cells of the offspring formed from that gamete.

What amount of does the parasite have compared to a virus or a bacterium?

- Organisms whose genetic material is not enclosed by a nucleus. The most common examples are bacteria.
- A nucleotide sequence in the operon system that is recognized by RNA polymerase as the site at which to begin transcription of RNA ...

Each time a virus's is copied, there is potential for mutation. These "typos" in the copying process introduce variations in viral genes that may affect the virus's characteristics.

Genome: all the genetic material of an organism.
Genotype: the inherited genetic constitution of an organism, see also phenotype.

Genome: All the in the chromosomes of a particular organism. The human genome consists of three billion bases, organized in about 100,000 genes on 23 chromosomes.

The joining of two bacteria cells when genetic material is transferred from one bacterium to another. Constitutive promoter. An unregulated promoter that allows for continual transcription of its associated gene.

Crossovers -- the exchange of between two paired chromosome during meiosis.

Crossing overThe exchange of genetic material between members of a pair of homologous chromosomes.

Altering the of cells or organisms to enable them to make new substances or perform new functions. (ORNL)

Since all cells come from existing cells, they must have some way of reproducing, whether that involves asexual (no recombination of genetic material) or sexual (recombination of genetic material).

Metagenomes - recovered directly from environmental samples - are sequenced and compared to the databases in order to characterize the biological community of a given habitat.

This form of rearrangement can be either (i) balanced, when the translocation does not result in any loss or gain of genetic material in the resultant gamete; or (ii) unbalanced, ...
