Answer:
Option D
Explanation:
The species probably has a small genome that is made up just two linear chromosomes such as that seen in the Jack jumper ant genome. It containing exactly two linear chromosomes could be a single pair of homologous chromosomes thus maybe indicating the cell is probably diploid but this is not enough to conclude on the ploidy.
Answer:
The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures
Explanation:
A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.
-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.
-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.
-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.
-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.
-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.
-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.
I think it’s c I’m not very sure
Answer:
this represents response to the environment
question is kind of strange but this depends on personal preference. I would go with the first one bc I'm too lazy lol. But if you're someone that's not, you might pick the last option because you don't want to run out before you don't even start the fire lol
