CHRs chromosomes

CLP codon diploid

DNA (deoxyribonucleic acid)

DNA-replication no growth on non-fermentable

Petites - gross deletion of mitochondrial DNA -substrates.

No mitochondrial genome.

One of the alternative forms of a gene, found on the same place on the chromosome.

The building blocks of proteins. They all have the same carbon backbone structure but differ from one another according to the individual side chain. Only 20 of the naturally occurring amino acids are commonly found in proteins.

A polyploid whose chromosomes are not a perfect multiple of ploidy.

A specialised haploid cell produced during meiosis.

A sac-like structure containing four spores in S. cerevisiae. Plural: asci.

A yeast strain that requires nutritional supplements to grow.

Two bases, linked by noncovalent forces, that pair in double-stranded DNA or RNA molecules.

The variable part of DNA. The nitrogenous bases of DNA are divided into two groups: purines [adenine (A) and guanine (G)] and pyrimidines [thymine (T) and cytosine (C)]. In RNA, thymine is replaced by uracil (U).

Cell division cycle mutants.

A DNA molecule usually obtained by reverse transcription of a mRNA molecule.

The attachment site of chromosomes to the mitotic or meiotic spindle.

Contour clamped homogeneous electric field.

Cluster homology regions.

Discrete physical units carrying genetic information. Each chromosome contains a long duplex DNA molecule and associated proteins. Usually, chromosomes are visible only during cell division. The number of chromosomes varies widely among different species.

Chromosome-length polymorphism.

A sequence of three nucleotides (in a DNA or mRNA), that encodes a specific amino acid to be incorporated into a protein.

A term used to describe an organism having two sets of identical chromosomes (2n). S. cerevisiae is chimeric, in that haploid and diploid forms exist.

The primary genetic material of all cellular organisms. It is a polymeric macromolecule composed of a repeating backbone of phosphate and sugar subunits to which different bases are attached. DNA is arranged in two opposing strands (the Watson-Crick double helix) in which the complementary bases form hydrogen-bonded basepairs across the two strands. The sugar backbone of DNA is composed of deoxyribose subunits.

Process of synthesis of a new DNA strand by a mechanism in which a preexisting strand (parental strand) is used as a template. Each new strand is complementary to the parent strand.

Discover How To Become Your Own Brew Master, With Brew Your Own Beer. It takes more than a recipe to make a great beer. Just using the right ingredients doesn't mean your beer will taste like it was meant to. Most of the time it’s the way a beer is made and served that makes it either an exceptional beer or one that gets dumped into the nearest flower pot.
