Which sequence shows the correct order of living things in a food chain?
kkurt [141]

The correct answer is option (A) leaves > deer > wolf.

A food chain is a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. Each level of the food chain is called the trophic level. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.

In the food chain given above, leaves > deer > wolf, deers feed on the leaves which are maximum in number comparitively, wolf feeds on the deer which are comparitively more in number than the wolves. This is the correct sequence of food chain showing the tranfer of energy and decreasing number of organisms with subsequent increase in the trophic levels.

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.
