Answer: rRNA
Explanation: mRNA is the messenger RNA (sequence determined by DNA) and it exits the nucleus and meets the tRNA (transfer RNA) in the ribosome or more specifically the rRNA (answer). I’m not sure what siRNA is, but I’m 99% sure the answer is rRNA.
#1. Keeping pressure in the plant. #2. Keeping structure from collapse while growing.
Answer:
The biological fitness of an organism is dependent on its ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population.

Answer:
This question lacks options, the options are:
A. They may act to turn on gene transcription.
B. They may act to turn off gene transcription.
C. They may become added to DNA, and then be transcribed.
D. They may remove a gene from DNA.
E. They may alter the nucleotide sequence in a gene.
Options A and B are the answers.
Explanation:
Prokaryotes regulate gene expression at the transcriptional level. Gene expression is the process whereby living organisms synthesize useful products such as protein from a gene. Prokaryotes such as bacteria control the expression of their genes via proteins that bind to DNA called REGULATORY PROTEINS.
These regulatory proteins also known as TRANSCRIPTION FACTORS, act to regulate genes by binding DNA. The binding of DNA either prevents or promote the binding of RNA polymerase in order for transcription to occur.
- Regulatory proteins which may act to inhibit transcription of DNA by turning off gene are called REPRESSORS.
- Regulatory proteins which may act to promote transcription of DNA by turning on gene are called ACTIVATORS.
