Answer:

Ans2-. Reverse osmosis is the right answer.

Explanation:

Distillation- Is the process used to purify liquids by selective boiling followed by condensation.

Reverse osmosis- This is the reverse of osmosis. In osmosis movement of liquid molecule from its higher concentraation to low concentration through a semipermeable membrane takes place . Reverse osmosis is a filtration using semipermeable   membrane which has small pores enough to pass pure water molecule and prevent the entry of solvents and bacteria.

Ultraviolet radiation- The water treatment to kill all the biological contaminants in water . In this treatment UV rays are passed over the water, UV radiations penetrates pathogens and kill them.

Chlorination- Chlorine is added in drinking water to disinfect it and kill all the germs present in it. As chlorine is a oxidizing agent, it penetrates easily inside the pathogens and destroys  their enzymes and cell wall and makes the water pure and  potable

What is the purpose of alternative splicing in eukaryotic cells? What is the purpose of alternative splicing in eukaryotic cells
Komok [63]

Answer:

Produce multiple polypeptide sequences from a single primary transcript.

Explanation:

Some genes produce more than one type of protein since the primary transcript encoded by these genes undergoes alternative splicing. These genes mostly have one segment that can serve either as intron or exon. Also called differential splicing, alternative splicing removes the segment as intron but retains it as an exon.

Splicing of the single primary transcript in different ways produces more than one version of mRNA from a single primary transcript encoded by a single gene. The alternative splicing allows the cells to produce multiple types of troponin proteins from single genes. These different troponin regulation muscle contraction in different muscles

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next. Mendel's Laws of Heredity are usually stated as:

1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.

2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.

3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.
