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.

4. How does an increase in orbital radius affect average orbital speed

allsm [11]

If there is an increase in orbital radius, this would also increase the average orbital speed or the velocity.

The orbital radius and the orbital speed is directly proportional. When the radius is increased, the orbital speed will also increase but it has to add energy to the system to increase the orbital radius.

Amylose is Select one: a. a long, straight glucose chain. b. branched glucose chains. c. a long, straight fatty acid chain. d. b

Gnoma [55]

Answer: A long, straight glucose chain (a major constituent of starch)

Explanation: Starch is mostly amylose (straight chain glucose polymer) but has varying amounts of branched glucose chains (amylopectin).

Fatty acids are hydrocarbons with a carboxylic acid group (-COOH) attached, so they are hydrophobic (don't mix with water) at one end and hydrophilic (water soluble at the COOH end)

Simple carboxylic acids don't have a long enough hydrocarbon chain to have this characteristic, e.g. CH3COOH acetic acid

Typical fatty acids found in nature include stearic acid with an 18-carbon chain

CH3-(CH2)16-COOH

In one to three sentences, describe what happens during the reduction stage of the Calvin cycle

Drupady [299]

In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADPH+
