Biology

7nadin3 [17]3 years ago
5 0

The tryptophan operon found in E coli is a group of genes that encode the enzyme that E coli use for biosynthesis. The operon can be turned on and off. The operon is regulated and controlled by TRP Repressor. When bound to tryptophan, the trp repressor blocks the expression of the operon.

The tryptophan operon is a repressible operon meaning that it is active when there's less TRP available. Therefore, to control the TRP operon when tryptophan is available, the tryptophan molecule must bind to the TRP repressor.

kirill115 [55]
Its definitely not A or D because there are 26 weeks in 6 months.

generally, a weight loss of 1-2 lbs per week is reasonable and safe. 

I would say B because it is unrealistic that someone would always lose 2lbs a week

In eukaryotic gene regulation, RNA interference occurs through:
Anit [1.1K]

Answer:

B. the action of microRNAs that block translation of specific mRNA molecule

C. the action of RNA–protein complexes that degrade the regulatory proteins responsible for initiating transcription.

Explanation:

RNA interference occurs what RNA prevent the translation of some gene this is done by neutralizing target mRNA molecule. It suppresses the effects of some desires genes through its action.

MicroRNA and small interfering RNA (miRNA and siRNA) are the major RNA that controls interference. siRNA and miRNA prevent translation by directing some enzmes complexes to denature the mRNA molecule needed for translation. They intiate post transcriptional splicing.

RNA interference is found in eukaryote and some animals and its initiated by enzyme Dicer that inhibits translation by degrading the enzymes action.
