SOVA2 [1]3 years ago
6 0

The correct answer is The elimination of catching marine life other than the intended fish.

Aquaculture can be defined as the cultivation of fishes, plants, crustaceans and other marine organisms to fulfill the purpose of food. The main advantage of this aquaculture is to produce the species that is intended. There is no need to cultivate everything that we don't want, only the desired species are grown for the commercial purpose. There is no need to catch the other marine life organisms that are not intended.

In your laboratory journal, describe the two tools of molecular biology that are often described as the scissors and glue for ma
MatroZZZ [7]

The "scissors" of the molecular biology are: DNA Restriction enzymes.

A restriction enzyme is a protein capable of cleaving a DNA fragment at a characteristic nucleotide sequence called a restriction site. Each restriction enzyme thus recognizes a specific site. Several hundred restriction enzymes are currently known.

Naturally present in a large number of species of bacteria, these enzymes have become important tools in genetic engineering.


The "glue" of the molecular biology are: DNA ligase

In molecular biology, DNA ligases are ligase-class enzymes that catalyze the formation of a phosphodiester bond between two segments of DNA. DNA ligases are involved in several essential cellular processes of DNA metabolism: in DNA replication, suture of Okazaki fragments, and in DNA repair and homologous recombination.


The use of these tools in molecular biology: Cloning

Molecular cloning is one of the bases of genetic engineering. It consists of inserting a DNA fragment (called insert) in an appropriate vector such as a plasmid for example. The new plasmid thus created will then be introduced into a host cell, generally the Escherichia coli bacterium. This will then be selected and multiplied to obtain a large amount of the plasmid of interest. Cloning a gene involves inserting it into a plasmid. A clone will be the bacterial transformant that contains this particular plasmid. In this case we speak of clone because all the individuals of the bacterial colony are genetically identical. Molecular cloning is thus different from reproductive cloning (creating an individual genetically identical to another but of a different age) or therapeutic cloning (making tissues from stem cells to perform transplants compatible with the recipient).

Molecular cloning requires restriction enzymes capable of cleaving the DNA, and DNA ligase capable of re-gluing the DNA fragments. Ligase was isolated for the first time from T4 bacteriophage. This enzyme is involved in the repair and replication of DNA. It can bind DNA fragments with compatible sticky ends. At higher concentration, this enzyme is also able to bind two ends of DNA as shown here. T4 DNA ligase works using ATP and Mg ++. It has an activity optimum of 16 ° C, but remains active at room temperature.

What is biodiversity an indicator of
Basile [38]
The cleanliness of a ecosystem or how healthy it is. It determines how clean an environment/ecosystem is. You need all types of animals living there, therefore making it more healthy. The more healthy, the more we can say that it is biodiverse.

A plasmid 41 twists and 6 right handed writhes. What is the Lk for this plasmid?
OLEGan [10]

Answer: Lk for this plasmid = 47

Explanation:

The formula to compute Lk is given by :-

Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)

Given: A plasmid 41 twists and 6 right handed writhes.

i.e. Twist (Tw) = 41   , Writhe (Wr) = 6

Then, Topological Linking Number (Lk) for this plasmid :  = 41+6

= 47

Hence, the Lk for this plasmid = 47
