The correct answer is that a bacteriophage lambda chromosome containing the human collagen gene, because Recombinant DNA is the name given to DNA molecules that have part of DNA derived from two or more sources, usually these sources are different species. Recombinant DNA technology is also known as molecular cloning or even gene cloning.

B. A bacteriophage lambda chromosome containing the human collagen gene

<h3>How is recombinant DNA produced?</h3>

Obtaining recombinant DNA is based on the molecular cloning technique. The process can be summarized as follows:

  1. The first step is to isolate a DNA fragment, which contains the gene of interest. Remember that each gene makes a protein.
  2. The gene of interest, now isolated, is placed in a medium with a fragment of circular bacterial DNA, the plasmid and the restriction enzymes.
  3. The bacterial plasmid has the ability to insert a fragment of DNA external to its own genome.

<h3>What is DNA and what is it for?</h3>

DNA is the structure responsible for the transmission of all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. Thus, the main function of DNA is to transport information contained in its sequences, called genes.

What are the cells in animals that are used to destroy bacteria and viruses after combining with lysosomes
AVprozaik [17]

T killer cell or Cytotoxic T cells  are the cells in animals that are used to destroy bacteria and viruses after combining with lysosomes.

<u>Explanation</u>:        

The T cells kills the bacteria and virus. The T cells can easily identify the pathogen when combined with the lysosomes. The activated T cells releases a material called perforin. This substance gets into the walls of the affected cell and punctures its walls. Due to hole in the walls, there happens discharge of fluid and electrolytes, which leads to the death of the cell.  The substance secreted is the cytolytic proteins from the lysosome which helps in destruction of the infected cells.

A plant with a large number of leaves could be danger of losing too much ___
Ganezh [65]

Answer:

A plant with large number of leaves could be danger of losing too much water.

Explanation:

Transpiration is a process that occur in plants which deals with the removal of water from the stomata present in the upper surface of leaves.

    The rate of transpiration is directly proportion to the number of leaves present in a plant.

   The presence of large number of leaves in a plant increases the transpiration rate of the later that is associated will losing too much water from the plant body.

Determine the statement that is logically equivalent to this conditional statement. If there is a thunderstorm, the lake floods.
Stels [109]

Answer:

This question lacks options, the options are:

A) If the lake does not flood, there is a thunderstorm.

B) If the lake floods, then there is not a thunderstorm.

C) If there is not a thunderstorm, the lake does not flood.

D) If the lake does not flood, then there is not a thunderstorm.

The correct answer is D

Explanation:

A conditional statement is a statement whose effect is dependent on another, it is usually recognized with the IF word. A Contrapositive of an original conditional statement, is the inverse of the converse of an original statement that doesn't change the meaning of the original statement.

For example; A -> B is the original conditional statement

Converse is B -> A

The Contrapositive is (not B -> not A)

The original conditional statement is: If there is a thunderstorm, the lake floods.

(This means that there is flooding of the lake in the presence of a thunderstorm)

The contrapositive of this statement is:

If the lake does not flood, then there is not a thunderstorm.

(This retains the meaning of the original statement. It means that the absence of a flood certainly means the absence of a thunderstorm)

Since the contrapositive is logically equivalent to the conditional statement, then the option D is the logically equivalent to the conditional statement.

Note: Option C is wrong because other factors might cause flooding of the lake, so the absence of thunderstorm doesn't mean there'll be no flooding of the lake but no flooding certainly means no thunderstorm, which option D is portraying.
