Enzymes are protein which act as a catalysts and speed up the rate of biochemical reactions with out changing the structure of the final product.

Enzymes can control the speed and specificity of the chemical reaction, and  the rate of biochemical reaction often influences enzymes and they can take place at a relatively low temperature; it   lower the activation energy.

Why do parrots mimic people?

Answers

Answer:

Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.

Explanation:

Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.

what are the similarities between this activity and actual mitosis

Answers

Mitosis and meiosis both involve duplication of a cell's DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells.

The DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.

What is mitosis?

Mitosis is defined as the cell-division process in which the chromosomes multiply and are equally distributed between the two daughter cells. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase are the five stages that make up mitosis. Meiosis is defined as a process by which a single cell undergoes two divisions, resulting in four cells with half the original genetic material.

Cell division occurs during meiosis as well as mitosis. The M-phase of the cell cycle is where both processes take place. The prophase, metaphase, anaphase, and telophase stages are typical for both cycles. DNA synthesis occurs during both cycles. A common goal of meiosis and mitosis is the division of the nucleus and its DNA into two daughter cells.

Thus, the DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.

RNA polymerase

Termination of transcription in bacteria occurs when the RNA polymerase encounters specific DNA sequences that lead to stalling of the polymerase. This results in release of RNA polymerase from the DNA template strand, freeing the RNA transcript.

Transcription is the process of synthesizing the RNA transcript from DNA.

The termination of transcription in bacteria occurs when RNA polymerase comes in contact with some particular terminator sequences that stalls the RNA polymerase letting it fall off.

In transcription, there is its initiation (start) and its termination (and end). Unlike humans with stop codons that terminates the process, the bacteria uses a terminator sequence which it transcribes and cause its fall off the DNA and releasing the RNA transcript.
