You are given an experimental problem involving control of a geneʹs expression in the embryo of a particular species. One of you

r first questions is whether the geneʹs expression is controlled at the level of transcription or translation. Which of the following might best
give you an answer?
a. You explore whether there has been alternative splicing by examining amino acid
sequences of very similar proteins.
b.You measure the quantity of the appropriate pre-mRNA in various cell types and
find they are all the same.
c. You assess the position and sequence of the promoter and enhancer for this gene.
d. An analysis of amino acid production by the cell shows you that there is an increase at
this stage of embryonic life.
e. You use an antibiotic known to prevent translation.

Which is a correct way to paraphrase the following:
beks73 [17]

Answer:

The paraphrase consists in saying with simpler words and with less technical words those obtained from a text. In this way, it facilitates its understanding, because the original information extracted is expressed in a simpler way.

The correct way to paraphrase is 2.  Every organism must acquire and use energy to build new structures, repair old ones, and reproduce

Explanation:

That option is referring to nutrition, which is the process by which nutrients contained in food meet the needs of cells and allow the proper development of organs. For example, certain organs such as the liver, brain, heart and kidneys, in normal conditions account for 60-70% of total energy expenditure of the organism, to which we must add the energy used in the synthesis and in the new tissue formation

If a cell has made extra copies of itself but then they divide in half , the first copy gets DNA but the second doesn't. What el
posledela
Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.
