Ribosomes are made up of rRNA and proteins. I was unaware of this until this reading

I was a bit confused by this term and found that it means synthesis of longer RNA sequences from shorter oligonucleotides which is guided by an RNA templet.

From Biology LibreText: Positive-sense viral RNA is similar to mRNA and thus can be immediately translated by the host cell. Negative-sense viral RNA is complementary to mRNA and thus must be converted to positive-sense RNA by an RNA polymerase before translation.

For some context about the information.

What does he mean by building blocks, is it DNA vs RNA?

RNA folding is a common process when RNA is synthesized. After researching the process is called cotranscriptional folding and is thought to impact gene expression and RNA function.

Key point of why only 3% of y1 male fruit flies are able to mate.

Just wanted to throw out that it may be important to study males due to the yellow gene being a sex-linked trait. Males will have a greater chance of inheriting the phenotype as they only require one X chromosome to display it.

Does this mean pesticides are a human made product that impact insects in the same capacity as allelochmeicals and secondary metabolites?

I didn't see any evidence pointing to the commonalities between human genes and fruit fly gene sequence, is this part of the reasoning why the species can be used for this purpose?

This is extremely interesting. I wonder what this means for the future of the species as it seems a greater concentration of larger males are mating with females. Are the mother's genetics what keep a variety of sizes present within a population?

I wonder is this attributes to domestication of fruit flies even if this is not a term used in relation to the species.

I am a bit confused by this. Does the placement of eggs impact natural selections placed upon D. melanogaster?

This is extremely important to cultivating D. melanogaster in a lab environment and points to the species adaptability to thrive in a variety of conditions.

Is there any way to test if they are neurotoxins, cytotoxins, or hemotoxins?

This relates to gbonet's comment on spiders and the Cnidaria's evolutionary similarities. In an article I read, it pointed out that the epithelia of three major salivary glands may be of ectodermal origin, and spiders deliver venom from modified salivary glands.

I am a bit excited that I predicted this information after researching a bit of the first few sentences!

This interested me and I was wondering if these would be considered planula larvae? If so it is extremely interesting and I wonder when their mouth and digestive tract develop. I also learned a new term-- lecithotrophy. Which means that they feed on egg yolk and materials put in the egg by the mother (I would assume the ladder is not applicable since the sea anemones shoot out their sperm and eggs to reproduce there is not time for preparation of greater material).
