Answer: check explanation.
Explanation:
Transcription is a process in which protein is being produced or synthesized. Transcription can also be defined as the transfer of genetic instructions in DNA to RNA. Transcription uses the DNA in the nucleus to make an RNA molecule. Then, the RNA will now leave the nucleus for ribosome(cytoplasm).
Transcription takes place in three steps and they are;
(1). INITIATION STEP: in this step, the RNA polymerase(an enzyme) binds to the promoter.
(2). ELONGATION STEP: in this step, we have the addition of nucleotides to the mRNA strand.
(3). TERMINATION STEP: In this step, we have the RNA polymerase crosses a terminating sequence in the gene. Here, the mRNA strand detaches itself from the DNA.
After the three steps above, we have the processing of the mRNA. This additional processing include, Splicing(removal of introns from mRNA), Editing( changes in nucleotides in mRNA) and Polyadenylation(addition of tail).
Answer:
Though there are some species where some organism can produce light with the help of some chemical reactions within their bodies. ... Almost all living organism releases heat during the process of respiration, but the amount of heat released during this process cannot cause any change in the environment.
Explanation:
Observing the replication of DNA molecules with a hand lens
A cell line refers to a population of cells from a multi cellular organism which normally has a fixed multiplication rate but due to mutation, the cells now have capacity to proliferate indefinitely. Cell lines are usually used to cultivate more cells. A cultured cell line which does not show density independent inhibition or anchorage is a tumored cell. This observation shows that the cell exhibit properties of tumors.
Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.
- Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
- A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
- Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.
