what is duplication and translocation?
234179
In a tandem duplication, duplicated regions are arranged next to each other on the same chromosome by nonallelic homologous recombination (Fig. 1, top). In translocated duplications, chromosomal duplications are translocated onto another chromosome by break-induced replication (Fig.

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. ... Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell.

A transposable element (TE, transposon, or jumping gene) is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size. Transposition often results in duplication of the same genetic material.

Homologous chromosomes are the two chromosomes that make a chromosome pair. ... This means that at the gene level, each of the homologous pair could be carrying different alleles. On the other hand, sister chromatids are the exact duplicates and arise by duplication when the chromosomes undergo mitosis.

Replication refers to the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules while duplication refers to the process by which the amount of DNA inside the nucleus gets doubled. Hence, this is the main difference between replication and duplication of DNA.

Originally Answered: What is the difference between moving and copying files or folders? Moving a file — to a new location — results in having just one file, but in a new location. Copying a file gives you two “copies” of the file — one in the old location and an additional one now in the new location.

The difference between copying and moving is that the copying command makes a duplicate of a file or directory to another location without affecting the original content while the moving command transfers the original file or directory to another location.

Replication is the process of duplicating the ones own genetic materials into two more identical copies, so that the similar information may get further transfer to the new daughter cells. Transcription involves the conversion of DNA into RNA, it is helpful in gene expression of the selected segment of DNA.

As nouns the difference between duplicate and copy is that duplicate is one that resembles or corresponds to another; an identical copy while copy is the result of copying (confer original); an identical duplication.

At the end of the division process, duplicated chromosomes are divided equally between two cells. These daughter cells are genetically identical diploid cells that have the same chromosome number and chromosome type.

Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

['Chromosomes become more coiled and can be viewed under a light microscope.', 'Each duplicated chromosome is seen as a pair of sister chromatids joined by the duplicated but unseparated centromere.']

During the first stage of meiosis, the HOMOLOGUES (1-23) are segregated into different cells, resulting in 2 cells that each have 1 copy of each of the 23 chromosomes (still duplicated from DNA replication). Swap bits and pieces of their chromosomes, shuffling the genome!

Clone just lets you select how many copies you want. Eg if you want to duplicate a field (or multiple fields) several times, then just select the field(s) and use clone. It will prompt for how many copies you want, then create that many in one go. Duplicate just does one duplicate of all selected fields at a time.

Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. ... When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment.

Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell.
