What are the pros and cons of CRISPR-cas9
professor190 [17]

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 :)

A mistake in DNA replication, in which the wrong base is placed in the growing DNA strand, can have profound effects on the desc
Klio2033 [76]

Answer:

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside  the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

                                      ATCGCAA

The Mutated strand is: TGGCGTT

                                       ATCGCAA

<em>The replicated strand is: GAATCAC</em>

<em>                                           CTTAGTG</em>
