comment Extending a small fragment of DNA
What exactly are you trying to do? If you give a clearer explanation of your experimental setup and goals, we might be able to help you further. As it is, this question is rather vague.

comment How do we know Denisovans had 46 Chromosomes
We know Denisovans interbred with other members of the genus Homo, therefore they must have had the same number of chromosomes. Individuals with different numbers of chromosomes cannot interbreed.

comment Link together all alike DNA sequences
What do you mean by alike? Size? Sequence? Methylation?

comment What the definition of a flanking residue?
@AliceD of course - D = Aspartate, E = Glutamate, A = Alanine, M = Methionine, T = Threonine. It's my favorite peptide :)

comment What the definition of a flanking residue?
Flanking means "next to something." So, in the amino acid sequence DEADMEAT, M is flanked by D on the N-terminal side and E on the C-terminal side.

comment If humans are 10cm taller than 200 years ago, then how can it be that we are “not much different” from humans 70000 years ago?
Humans are taller and live longer than our ancient ancestors because of vastly improved diet, a less dangerous lifestyle, and modern medical care. Genetically, we are quite similar, which is why we are still classified as the same species.

comment Does anyone have some references on using metal halide lamps in a greenhouse?
I'm voting to close this question as off-topic because it is more suited to Gardening & Landscaping.

comment How do non-dimorphic birds distinguish sex of possible partners/rivals?
Since we're not birds there's no way of knowing for sure, but I would imagine calls/songs and possibly pheromones have something to do with it. There may also be anatomical differences as well that humans haven't discovered yet.

comment Effect of cytokines on dengue virus
Be that as it may, this question is still overly broad - if you have no biological background, an answer would essentially need to give you a review of immunology before even attempting to explain what each cytokine does. From the help center, "If you can imagine an entire book that answers your question, you’re asking too much." I strongly suggest reading How do I ask a good question? and significantly revising your post. Tell us what you know, and what exactly you're looking for. Please limit yourself to one question.
