Twisted Helix (Double helix),The double helix, which resembles a twisted ladder, is the shape of DNA. Sugar and phosphate molecules alternately make up the sides of the ladder. It is deoxyribose, the sugar.
DNA is made up of a double helix. To put it another way, it is a spiral-shaped, double-stranded molecule. Deoxyribose sugars alternate with phosphates to create the molecule's exterior, or the rails of the stairway. The "backbone" of the molecule is another name for this area. The ladder's rungs are made up of pairings of the four different nitrogen bases.A lengthy polymer is created when the phosphates and sugars of nearby nucleotides connect. They demonstrated how the twisted uprights of the DNA ladder are made up of alternating deoxyribose and phosphate molecules. The complementary pairings of nitrogen bases that make up the ladder's rungs are A always paired with T and G always paired with C.DNA Replication Deoxyribonucleic acid, also known as DNA, resembles a long, spiralling ladder. It only has carbon, hydrogen, oxygen, nitrogen, and phosphorus as its main atom types. The sides of the DNA ladder, or the sugar-phosphate backbone, are made up of combinations of these atoms.To know more about double helix check the below link:

Why do some cells divide faster than others and some cells do not divide after they are formed?.
Some cells divide faster than others due to their specific genetic makeup and the environment they are in.
What are cells?
Cells are the basic structural and functional units of all the living organisms. They are the building blocks of life, and they make up the tissues and organs of the body. Cells are composed of a variety of components, including a nucleus, cytoplasm, cell membrane, and various organelles, such as mitochondria and lysosomes. Cells are responsible for all of the activities that keep us alive, including respiration, digestion, and reproduction.
Cells that are part of the immune system are able to rapidly divide in order to produce more copies of themselves to fight off infection. Other cells, such as nerve cells, do not divide once they are formed, as they are not able to regenerate and must stay in place to transmit signals. The environment a cell is in also plays a role in how quickly it divides; cells in a nutrient-rich environment are more likely to divide quickly.

A man had a pointed line, a a heterozygou cae. Hi wife had no pointed hairline. What i their probability of having children with pointed hairline?
Any child born to parents who are heterozygous (W w) has a 75% probability of developing widow's peak .
All conceivable genotypic pairings in the parents can be found using a Punnett square. There are a few key differences in a pedigree that shows a characteristic that is dominantly inherited.
If a characteristic is dominant, just one allele is needed to manifest the trait. A recessive allele, if present, will be hidden by a dominant allele. Using a capital letter, a dominant allele is identified (A versus a). There are three possible combinations because each parent contributes one allele: AA, Aa, and aa. The dominant characteristic is phenotypically expressed in offspring with genotypes AA or Aa, whereas the recessive trait is displayed in aa individuals.
Example:
All of the offspring of parents who are homozygous dominant (WW) and homozygous recessive (WW) will be heterozygous (WW) and have a widow's peak.

what is the physiological reason males have an unlimited number of sperm but women have a limited number of eggs?
Answer:I understand that the question you are looking for is:
what is the physiological reason males have an unlimited number of sperm but women have a limited number of eggs?
The male have maximum have an unlimited number of sperm than woman because Sperms are produced in large numbers to ensure the fertilisation of the ovum.
Explanation:
Why does fertilisation require millions of sperm cells but only one egg?
There must be a considerable amount of sperm in the semen for the ovum to be successfuly fertilised. The human female reproductive system requires sperm to swim through it in order to reach the ovum in the fallopian tube, hence the sperm must include a lot of sperm.
Why do you require countless sperm?
The likelihood that you will fertilise the egg instead of your neighbour increases as you move more of your sperm toward the egg.
For males of any species, this form of competition is necessary for evolutionary reasons.
It is impossible to pass on your genes if another person's sperm fertilises an egg.
Ejaculate typically contains 200 to 600 million sperm, which enhances the likelihood that some will finally reach a developed egg and that just one will be able to enter and fertilise it.
What is the most sperm that a man can hold?
If a man hasn't ejaculated in 4-5 days, there are roughly 300 to 800 million sperm cells preserved during spermatogenesis.
And fresh ones are continually being created.
Sperm cells expire quickly, therefore if a guy doesn't ejaculate for two weeks, the expired cells will begin to leak out and be eliminated in the urine or he may experience nighttime emissions to eliminate the expired cells.
A man's body may therefore house a total of 5–6 ml and 800.000.000 cells.
After two weeks of abstinence, the expired material is eliminated, and semen proteins and fresh cells are continually created.

The option A is correct
What is Fertilization?
A pregnancy starts with fertilization, when a woman's egg joins with a man's sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
What happens throughout the primary fertilization process?
There are four distinct mechanisms that make up the phases of fertilization:
Sperm preparation comes first, followed by sperm-egg recognition and binding, sperm-egg fusion, fusing of the pronuclei of the sperm and the egg, and activation of the zygote.
What three phases of fertilization are there?
Sperm capacitation and acrosome reaction, sperm-egg binding and fusion, and cortical reaction and oocyte activation are the three primary phases of fertilization. In the female genital canal, sperm cells undergo sperm capacitation, which gets them ready for the acrosome response.
