Where in the cell cycle does the type of mutation in chromosomal translocation occur?

Biology

Makovka662 [10]3 years ago

During metaphase 1 of meiosis of the cell cycle chromosomal translocation occur.

Explanation:

Chromosomal translocation is abnormal phenomenon when a fragment of chromosomes detaches and gets stick to the non-homologous chromosome in an individual. These are causative of aneuploid, cancer and infertility in organism.

In metaphase 1 of meiosis the chromosomes gets aligned on the metaphase plate. This leads to surety of equal number of chromosome in the cell.

Chromosomal translocation are seen in metaphase 1 because it is the phase of rearrangement of chromosomes where fragments easily gets attach to the other chromosome.

weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

The early stage of protein purification often uses a procedure known as "salting out". This is typically done by treating the pr
Vikki [24]

Answer:

Answer is Ammonium sulfate.

Explanation:

The method of adding ammonium sulfate to a protein solution is known as precipitation. This is because the addition of ammonium sulfate will reduce or decrease the solubility of the protein. And as the ammonium sulfate is being increased, so also the solubility of the protein will be decreasing.

And at the long run, the protein will be precipitated. This is what is referred to as the 'salting out' procedure.

How did the carbon atom get into cellular respiration
Pepsi [2]

Carbon atoms are converted into metabolites like acetic acid, lactic acid, aldehydes, etc via the action of different bacteria. In the process of fermentation or cellular respiration, carbon atoms are cleaved into three carbon molecule called pyruvate then eventually forming into metabolites.

galina1969 [7]

Answer:

The correct answer is-

Hypothesis: Antibiotics cause weight gain in cows.

Independent Variable: Antibiotic pill

Dependent Variable: Weight of cow

Control Group: a group of cows gets a placebo pill

Experimental Group: a group of cows gets an antibiotic pill

Explanation:

The Independent variable is the variable that causes the response from the dependent variable or affects the dependent variable in this study the antibiotic pill affects the weight of cows so The independent variable is an antibiotic pill and the dependent variable is the weight of cows.

The control group is the group of subjects that did not get the treatment in a scientific study in the case of this study group of cows that receives the placebo pill is the control group and the experiment group is subjects that receive the treatment which is a group with the antibiotic pill.

One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, spec
Arte-miy333 [17]

Answer and Explanation:

<em>Biodiversity </em>composes of different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species form.

Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

Biodiversity, in equilibrium with abiotic factors, provides ecosystem services, which are important for the maintenance of all forms of life, including human beings.  

<em>Ecosystem services</em>

When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:

  • Provision or supply:

These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.

  • Regulation:

Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.

  • Cultural:

Refers to not the material benefits. Ecosystems provide a recreational place or area to spend time and learn. They provide a spiritual/religious space, are a source of inspiration. Ecosystems are cultural patrimony and the source of scientific knowledge.
