Hey there!
The sides of DNA have rails, or the sides of them that keep them together- and what's amazing is you can't even see it.
They're made of sugar (deoxyribose) and phosphate molecules. They alternate, so sugar, phosphate and so on.
Hope this helps!
Answer:
In prokaryotes nucleus is not present so replication transcription and translation takes place in the cytoplasm in the prokaryotes while in eukaryotes replication and translation takes place in the nucleus.
In prokaryotes, transcription and translation are coupled but in eukaryotes, transcription and translation are separated by nucleus and post-transcriptional modification takes place in eukaryotes, not in prokaryotes.
In prokaryotes, ATP synthesis takes place in cell membranes because they do not have mitochondria. Eukaryotes contain mitochondria where ATP synthesis takes place in them.
The answer is C) 4.

It is known that gametes are haploid cells. Haploid
cells have only one allele in the loci. Each gamete will contain each of these four different alleles. That means that there will be four different types of gametes containing four different alleles.</span>

Explanation:
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual.
In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself. The evolution of sexual reproduction is a major puzzle for biologists. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce[1] and organisms only pass on 50% of their genes.[2]
