A. Lysogeny.
B. Lysogenic conversion
C. Temperate phages
D. Induction
E. Prophage
Explanation:
Lysogenic replication or lysogeny is the process of a bacteriophage invading the host’s cell, grows, replicates for generations, multiply by undergoing lysis in the host’s cell.
The basic steps of lysogenic or lytic life cycle are:
- Attachment of the phage with the host’s surface
- Penetration of the DNA to the host’s cell
- Biosynthesis of phage protein through replication of phage DNA
- Maturtion and assembly of phage particles
- Lysis to release new phages
Apart from these, under certain conditions, lysogenic replication can occur by:
Lysogenic conversion where the phenotype of a normal bacterium is converted and becomes pathogenic and produces harmful proteins and cause diseases
Other phages which can undergo lysogenic replication cycle are called temperate phages
Prophage is a type of bacteriophage which is inactive but remains in the chromosome of the host cell which powers the bacterium to be resistant to infections caused by other viruses.
Induction is the process of excision of the phage from the host’s chromosome through physical or chemical methods.
You have no choices however, A gene pool is defined as a sum total of all the genes present in an inter-breeding population at a specific time. It includes all the alleles of all the loci within the genes of a interbreeding population or species. The composition of the gene pool of a population can change with course of a time due to evolution
It must be known that there is an interdependent relationship between meiosis and sexual reproduction. During sexual reproduction, meiosis generates a genetic variation in the offspring because it randomly shuffles genes across chromosomes and then randomly segregates half of those chromosomes into each gametes. These two gametes or sex cells then fuse randomly to form a new organism. One of the key factors in evolutionary fitness and biological diversity is genetic variation. This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation.
To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.
Reproductive organs of both men and women are vital to create a child. But it must be noted that both can live without them. There are situations that sometimes necessitates the removal of such organs especially if he or she is inflicted with cancer or other diseases.
Answer:
Invasive species also have the potential to disrupt vital ecosystem functions, such as water flow, nutrient cycling, fire systems, or soil composition. An example of this is the Tamarix species. It not only uses large amounts of water, it changes the soil chemistry, making it more saline.
