The options attached to the question above are given below:
A. All living and nonliving things consist of one or more cells.
B. Cells and living organisms are spontaneously created.
C. Cells are the most complex unit of structure and function in living things.
D. A cell is the basic unit of structure and function of all organisms
ANSWER
The correct option is D.
The cell theory is one of the major theories in biology and it states the facts about living cells. The theory states that, the cell is the most basic unit of all organisms and all living organisms are made up of one or more cells. The organisms that are made up of only one cell are described as unicellular while those that possess many cells are described as multi cellular. The theory also states that all cells come from pre-existing cells.
Answer:
It has incomparable advantages over other gene editing tools.
Explanation:
For example, the CRISPR-Cas9 system has more target sites than ZFNs and TALENs, and Cas9 has many variants that can be used in a variety of studies. Moreover, the system is extremely easy to use and can be executed in almost any laboratory.
The most important advantages of CRISPR/Cas9 over other genome editing technologies is its simplicity and efficiency. Since it can be applied directly in embryo, CRISPR/Cas9 reduces the time required to modify target genes compared to gene targeting technologies based on the use of embryonic stem (ES) cells.
Disadvantages of CRISPR technology: CRISPR-Cas9 off-target; The effect of off-target can alter the function of a gene and may result in genomic instability, hindering it prospective and application in clinical procedure.
this the best i got, hope it helps :)
Explanation:
If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
False, a lipid bilayer is a MOSTLY apolar cell structure,which means polar molecules can't easily go through it
Answer:
DNA- DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. ... DNA is in each cell in the organism and tells cells what proteins to make.
