A fragment that chromosome 21 reattaches come chromosome 21, but in the reverse direction. What is the name offered to this change? trisomy 21deletionduplicationtranslocationinversion
An turning back occurs once a fragment reattaches come the initial chromosome yet in the reverse direction. Usually, this aberrations an outcome in under harmful impacts than various other chromosomal alterations as the genes are still existing in their regular number.

During meiosis, homologous chromosomes occasionally "stick together" and do not separate properly. This phenomenon is recognized as _____. Cellular sterilitymeiotic failuregametic infertilitynondisjunctionsticky chiasmata
During meiosis I, homologous chromosomes kind a tetrad. What walk this accomplish? A) This brings the chromosomes into alignment so the crossing over can create brand-new combinations of genes current on a solitary chromosome.B) cross over have the right to occur, creating brand-new combinations of chromosomes with their live independence alignment throughout the metaphase plate.C) It permits for the procedure of crossing over to occur, i beg your pardon reduces the number of chromosomes current in the cell.D) A chiasma creates as crossing end occurs, which ultimately reduces the variety of chromatids per chromosome.
A)Crossing over does this by exchange of equivalent parts between homologous chromosomes, creating a patchwork the maternal and paternal chromosome segments follow me a solitary chromosome.
In a cell containing 10 chromosomes, meiosis results in the formation of daughter cell containing _____ chromosomes.51020400
During meiosis, the occasions that happen in _____ are similar to those that take place in _____ the mitosis. Prophase i ... Prophasemetaphase i ... Metaphaseanaphase i ... Anaphase IImetaphase II ... Metaphasetelophase II ... Telophase I
metaphase II ... Metaphase Meiosis II is virtually similar to mitosis, which separates sister chromatids, but unlike meiosis I, i beg your pardon separates homologous chromosomes. However, every daughter cell developed by meiosis II has only a haploid, not diploid, collection of chromosomes.
Which the the adhering to statements about the role of mitosis is false? Mitosis allows organisms come grow. Mitosis permits organisms come regenerate lost parts. Mitosis permits organisms to repair tissues. Mitosis permits organisms come reproduce asexually. Mitosis allows organisms to generate hereditary diversity.
What is the difference in between a bright tumor and a malignant tumor? benign tumors room a mass of basically abnormal cells; malignant tumors are an abnormal fixed of essentially normal cells. Benign tumors carry out not metastasize; malignant tumors do. Bright tumors metastasize; malignant tumors execute not. Light tumors will certainly not kill you; malignant tumors will. Benign tumors spread past their initial site; malignant tumors remain at their initial site.
Benign tumors perform not metastasize; malignant tumors do. Malignant tumors spread from their site of origin to various other parts of the body.
Which the the adhering to is a function of tree cell department that distinguishes that from pet cell division? lack of cytokinesisformation that a cell platedisappearance and subsequent reappearance the the nucleolusproduction of four (rather 보다 two) new cells per mitotic divisionformation the a cleavage furrow
Which that the following occurs during mitosis? 2 genetically various daughter cell result. Organelles replicate. Chromatids separate. Chromosomes replicate. The cabinet divides right into two separate cells.
The step of mitosis throughout which the chromosomes move toward separate poles that the cell is _____. telophase anaphase metaphase prophase cytokinesis
anaphaseAnaphase begins when the paired centromeres of every chromosome separate, liberating the sister chromatids, which start moving toward opposite poles that the cell.
Which the the complying with is a vital difference in between meiosis and also mitosis? Chromosomes align at the metaphase plate. Chromosomes condense. Chromosomes move to the contrary poles. A spindle device forms. Synapsis occurs.
