What is the function of mRNA?
stich3 [128]

mRNA

Messenger RNA is used to copy and encode genetic information from DNA base pairs by forming complementary strand of RNA molecule from the nucleus of the cell to the cytoplasm.

tRNA

Transfer RNA reads sequence of nucleotide from messenger RNA and translate them into proteins or amino acids during proten synthesis.

Transcription

This is the first step in gene expression where information from DNA is copied into a complementary strand of RNA molecule using RNA polymerase enzyme.

Translation

Messenger RNA made from the process of transcription travels to the ribosomes in the cytoplasm where proteins are produced using transfer RNA to copy the information.

The use of DNA to make proteins.

Through gene expression (central dogma of biology), the DNA molecule carries information, a gene code, in form of base pairing sequences that are transcribed to RNA and further translated to functional proteins or amino acids.

From what you should now know about bacterial taxis and nodule formation, predict how a rhizobium would respond to a flavonoid.
andreev551 [17]

Answer;

-The bacterium would exhibit positive chemotaxis.

Explanation;

-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.

Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.

olasank [31]
The above statement is very true. 
The inguinal hernia results from abnormal enlargement of the opening of the inguinal canal through which vessels, spermatic cord and nerves of male reproductive system pass (in males only). Hernias are protrusion of visceral through abdominal wall. They may be congenital or acquired ; Acquired occurs when a natural weakness is further aggravated by either a strain or a direct blow.

antoniya [11.8K]

Answer:

The conclusion is that different matters have different biomass percentages.

Explanation:

Different matters have different biomass percentages because they are formed from different elements. each biomass is formed from the elements such as carbon, oxygen, hydrogen and nitrogen. for example, the human body is composed of 30 percent of biomass while 70 percent is water. the percentages of different elements are carbon (12%), nitrogen (0.6%), hydrogen (62.9%), oxygen (24%), calcium (0.24%) and phosphorus (0.14%). At each level, only 10 percent of biomass is transferred to another level and remaining 90 percent releases in the form of heat.
