Identical and obviously duplicated gene sequences have gotten from one chromosome to another by chromosomal translocation.

In terms of genetics, a translocation takes place when chromosome fragments and the (often two) fragmented portions reassociate with other chromosomes. For the diagnosis of several genetic diseases and syndromes, the finding of chromosomal translocations can be crucial.

Multigene families are groups of related or identical genes that have developed by gene duplication. It is thought that a single ancestral gene was duplicated and varied to create multigene families. The multigene families that code for actins, hemoglobins, immunoglobulins, tubulins, interferons, histones, etc. are a few examples.

Why is the archaea domain closer to eukarya than bacteria?
harkovskaia [24]

Answer:

Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.

Explanation:

Options for this question are:

  • <em>They both lack a nucleus and contain  cytoplasm. </em>
  • <em>The unique functional adaptations of Archaea are more similar to Eukarya adaptations.  </em>
  • <em> They both evolved in the same geological time period. </em>
  • <em> </em><em>Genetically, the Archaea are more similar to Eukarya than Bacteria. </em>
  • <em> They both have membrane-bound organelles. </em>
  • <em> Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.</em>

Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.

The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.

7) How many alleles will a gamete have for any one gene?
pantera1 [17]

Answer:

Explanation:

<em>Each trait of an organism is determined by discrete units called genes and individuals carry two alleles for each gene. (Mendel didn't actually discover genes though). Each gamete of an individual carries only one allele of each gene (this is Mendel's Law of Segregation).</em>

3. Which of the following is an accurate description of mitosis and meiosis? A. Meiosis produces two haploid daughter cells, whi
maria [59]

The correct answer is - B. Mitosis produces two diploid daughter cells, while meiosis produces four haploid daughter cells.

The processes of mitosis and meiosis are often confused with one another, mostly because of the similarity in their names.

The mitosis is a type of cell division where the end result is two daughter cells, each of the cells has the same number and kind of chromosomes as the parent nucleus. Thus is typical for the growth of tissue.

The meiosis is a type of cell division where the end result is four daughter cells, each of the cells having half the number of chromosomes of the parent nucleus. This is typical for the gametes and the plant spores.
