How plants avoid incest: different versions of the same gene can be either dominant or recessive. A small non-coding RNA mediates such differences in dominance as part of a system that prevents inbreeding in plantsDaphne GoringEmily Indriolo...
What are the sources of genetic variation in meiotic cell division? What is the relationship between bivalents and homologous chromosomes? What are different forms of the same gene called? a. factors b. alleles c. genes d. chromosomes e. chro...

Sexual can be defined as two distinct forms (behavior, physiology, or structure), one found either exclusively or predominantly in males and the other in females. a. segregation b. divergence c. dimorphism d. dynamism e. diploidy The human reproductive system, though different in males and fema...
CPX forms a stable complex in the orthosteric site; HSM shows several binding modes and eventually vacates the binding site spontaneously Histamine unbinding pathway. Schematic illustration of the four phases of the spontaneous unbinding and exit pathway of the HSM ligand (curve in yellow), showing...
These EST sequences provide valuable information to further understand molecular mechanisms of plant sex determination process and forms a rich resource for future functional genomics analysis, marker development and cucumber breeding.Background Cucumber (Cucumis sativus L.) is an economically and ...
(carrying in homoplasmic form either the mitochondrial tRNALysA8344G mutation associated with the myoclonic epilepsy and ragged red fiber (MERRF) encephalomyopathy or a frameshift mutation, isolatedin vitro, in the gene for the ND4 subunit of NADH dehydrogenase) to undergo transcomplementation of ...
The roles of the FGF family growth factors and their receptors (FGFRs) in zebrafish embryos were examined using variously modified versions of the four FGFR genes (fgfr1–4). Constitutively active forms of all of the examined FGFRs (ca-FGFRs) caused dorsalization, brain caudalization, and sec...
Explain, briefly, how the organization of eukaryotic genes makes it possible that a single gene can be expressed as multiple versions of the same protein. Describe the various DNA structures within bacteria. Describe the various techniques used in DNA cloning. Explain the contributions of differ...
Alleles are a. sometimes referred to as genotypes. b. can either be dominant or recessive. c. different molecular forms of the same gene. d. All of the above Alleles are different versions of a ___. a. chromosome b. chromatid c. phenotype d. gene e. genotype How are all...
