Which is NOT a role played by a type of RNA in protein synthesis?
O mRNA transcribes the DNA template.
rRNA makes up ribosomes, which translate the genetic code into a protein.
O tRNA pairs RNA bases with amino acids.
O pRNA is the product of chemically linked amino acids.
Answer:
pRNA is the product of chemically linked amino acids.
Explanation:
All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.
There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.

Which distribution pattern do the oyster larvae exhibit?
O A. clumped
OB. stationary
C. random
OD. uniform
Answer:
D. Random
Explanation:
The term "population distribution pattern" refers to the method or form in which population of a certain organism living in a certain area occupy that area.
For example:
Uniform distribution pattern in which organisms are arranged in a equal or regular manner in the area. This gives a competition to the organisms of the area with reference to each other.
If we talk about Oysters, they are able to travel many and many kilometers across a certain area. Therefore, they don't stay at a place in a regular manner and this gives them random distribution pattern.
Hope this helps you.. Good luck!
