lapo4ka [179]

Options are not given in the question. The complete question is as following:

Gene expression is often assayed by measuring the level of mRNA produced from a gene. If one is interested in knowing the amount of a final active gene product, a potential problem of this method is that it ignores the possibility of _____.

A) chromatin condensation control

B) transcriptional control

C) alternative splicing

D) translational control

Answer:

D) translational control

Explanation:

Gene expression is the mechanism used in the production of a functional gene product through information from a gene. This results in much more rapid cellular change by direct protein concentration regulation.

Translational regulation refers to regulating the protein concentrations synthesised from its mRNA. This control is of great importance for the cellular response to stressors, signs of growth and differentiation. This results in much more rapid cellular change by direct protein concentration regulation.

Hence, to evaluate gene expression it is important to measure the possibility of translational regulation as most of the time, function of the stop codon is ignored by ribososme which leads to long peptide chains and interfer with gene expression.

So, the correct answer is D).

Which factor most likely caused animals and plants in india to differ greatly from species in nearby southeast asia? which facto

STatiana [176]

The correct answer is - India was a separate continent until 45 million years ago.

India and Southeast Asia despite bordering one another have great differences in the flora and fauna. The reason for that is that India was a separate continent until 45 million years ago, while Southeast Asia was part of Asia. Because of the long period of isolation before the collision with the Asian mainland, the flora and fauna of India developed unique characteristics, mostly found only in India, and some being shared between India and Madagascar as it was the last land with which it was in contact before becoming a separate continent and started moving towards Asia. The differences are bigger in the southern half of India, while in the northern half they are lesser and have more similarities with the flora and fauna of Southeast Asia.

damaskus [11]

ANSWER: the genetic material is duplicated interphase.

The process by which a cell which has previously replicated chromosomes in the nucleus of the cell is separated into two identical sets of chromosomes is known as mitosis. Mitosis is the division of the mother cell into two daughter cells, these daughter cells are genetically identical to each other and to the parent cell. It is a form of nuclear division. Mitosis is generally followed by cytokinesis, this process divides the nuclei, cytoplasm, cellular organelles and cell membrane into two cells of roughly equal shares of these cellular constituents. The M phase of the cell cycle is of mitosis and cytokinesis together. Cell division is a process with sequence of steps that enables organisms to grow and reproduce. Genetic material is replicated in parent cells and is distributed equally to the two daughter cells. Cells undergo a period of growth called interpahse before entering mitosis. During the interphase, the genetic material replicates and the organelles prepare for division. In the process of mitosis, the parent's cell genome is transferred into the two daughter cells. The daughter cells are similar to each other and to their parent cell.

The cell's genome is composed of chromosomes that are complexes of tightly coiled DNA that contain the genetic material which is vital for the proper functioning of the cell.

The process of mitosis begins when the chromosomes condense. In most eukaryotic cells, the nuclear membrane segregates the DNA from the cytoplasm into membrane vesicles. The ribosomes also dissolve, the chromosomes align themselves. Microtubules pull apart the sister chromatids of each chromosome. The daughter chromosomes are pulled towards opposite ends. Nuclear membrane forms around the separate daughter chromosomes. In animal cells, the area of cell membrane pinches inwards, to form the two daughter cells, the imaginary line is called the cleavage furrow which separates the developing nuclei. In plant cells, the new dividing cell wall is constructed in between the daughter cells. The parent cell will thus split in half and give rise to two daughter cells.
