Constitutive heteroch romain describes the inert state of permanently nonexpressed sequences, usually satellite DNA Constitutive mutations cause genes that usually are regulated to be expressed without Contractile ring is a ring of actin filaments that forms around the equator at the end of mitosis and is responsible for pinching the daughter cells apart Controlling elements of maize are transposable units originally identified solely by their genetic properties. They may be autonomous (able to transpose independently)or nonautonomous(able to element) Coordinate regulation refers to the common control of a group of genes Cordycepin is 3 deoxyadenosine, an inhibitor of polyadenylation of RNA Core DNA is the 14.6 bp of dNA contained on a core particle Core particle is a digestion product of the nucleosome that retains the histone octamer and has 14.6 bp of DNA; its structure appears similar to that of the nucleosome itself. Corepressor is a small molecule that triggers repression of transcription by binding to a regulator protein. Cosmids are plasmids into which phage lam bda cos sites have been inserted; as a result, the plasmid dNa can be packaged in vitro in the phage coat Cot is the product of DNA concentration and time of incubation in a reassociation reaction Cot is the Cot required to proceed to half completion of the reaction, it is directly proportional to the unique length of reassociating DNA Cotransfection is the simultaneous transfection of two markers Crossing-over describes the reciprocal exchange of material between chromosomes that occurs during meiosis and is responsible for genetic recombination Crossover fixation refers to a possi ble consequence of unequal crossing-over that allows a mutation in one member of a tandem cluster to spread through the whole cluster (or to be eliminated) Cruciform is the structure produced at inverted repeats of dNA if the repeated sequence pairs ith its complement on the same strand (instead of with its regular partner in the other strand of the duplex) Cryptic satellite is a satellite DNA sequence not identified as such by a separate peak on a density gradient; that is, it remains present in main-band dna ctDNA is chloroplast DNA Cyclic AMP(cAMP)is a molecule of AMP in which the phosphate group is joined to both the 3 and 5 positions of the ribose, its binding activates the CaP, a postive regul ator of prokaryotic transcription.

Constitutive mutations cause genes that usually are regulated to be expressed without regulation. Contractile ring is a ring of actin filaments that forms around the equator at the end of mitosis and is responsible for pinching the daughter cells apart. Controlling elements of maize are transposable units originally identified solely by their genetic properties. They may be autonomous (able to transpose independently) or nonautonomous (able to element). Coordinate regulation refers to the common control of a group of genes. Cordycepin is 3’ deoxyadenosine, an inhibitor of polyadenylation of RNA. Core DNA is the 14.6 bp of DNA contained on a core particle. Core particle is a digestion product of the nucleosome that retains the histone octamer and has 14.6 bp of DNA; its structure appears similar to that of the nucleosome itself. Corepressor is a small molecule that triggers repression of transcription by binding to a regulator protein. Cosmids are plasmids into which phage lambda cos sites have been inserted; as a result, the plasmid DNA can be packaged in vitro in the phage coat. Cot is the product of DNA concentration and time of incubation in a reassociation reaction. Cot 2 1 is the Cot required to proceed to half completion of the reaction; it is directly proportional to the unique length of reassociating DNA. Cotransfection is the simultaneous transfection of two markers. Crossing-over describes the reciprocal exchange of material between chromosomes that occurs during meiosis and is responsible for genetic recombination. Crossover fixation refers to a possible consequence of unequal crossing-over that allows a mutation in one member of a tandem cluster to spread through the whole cluster (or to be eliminated). Cruciform is the structure produced at inverted repeats of DNA if the repeated sequence pairs with its complement on the same strand (instead of with its regular partner in the other strand of the duplex). Cryptic satellite is a satellite DNA sequence not identified as such by a separate peak on a density gradient; that is, it remains present in main-band DNA. ctDNA is chloroplast DNA. Cyclic AMP (cAMP) is a molecule of AMP in which the phosphate group is joined to both the 3’ and 5’ positions of the ribose; its binding activates the CAP, a postive regulator of prokaryotic transcription. Cyclins are proteins that accumulate continuously throughout the cell cycle and are then
