Answer:
DNA rearrangment.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
DNA rearrangment can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Hence, the ability of an individual to produce over a million different antibody molecules doesn't require the use of over a million different genes; rather, this wide range of antibody production is due to deoxyribonucleic acid (DNA) rearrangment.
Answer:
regulates which materials enter and leave the cell
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome
The following protocols in the facility would the care aide advocate changing are D) Wound dressings are applied promptly to all identified or potential pressure ulcers.
Dressings must be modified often and as quickly as they grow to be dirty with urine or feces to save you wound contamination. Each dressing extrade must be observed through concurrent wound reassessment.
hydrocolloid dressings – include a gel that encourages the boom of latest pores and skin cells withinside the ulcer, whilst retaining the encompassing wholesome pores and skin dry. different dressing types – which include foams, films, hydrofibres/gelling fibres, gels and antimicrobial (antibiotic) dressings can also be used.
