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.

A polarized cell Group of answer choices has a charge imbalance across its membrane. includes most cells of the body. exhibits a
oksano4ka [1.4K]

Answer:

True.

Explanation:

The unequal distribution of ions inside and outside of the cell makes the membrane potential of the cell. The potential is important for the conduction of the impulse and generation of the action potential.

The resting membrane potential of the nerve impulse is maintained by the presence of large potassium ions inside the cell. The resting membrane potential is -70mV. The depolarization of the membrane occurs due to influx of the sodium ions.

Thus, the answer is true.
