Answer:
prevent excessive loss of water
Explanation:
The epidermis is a single layer of cells covering all plant organs. The epidermal cells are elongated in the direction of stem length and flattened. They have no chloroplast and their outer walls are covered by a waxy cuticle that prevents excessive loss of water through evaporation. The cuticle also protects the inner tissues from infection and mechanical injury.
E.coli is a bacteria cell.
vertebrae, sacrum, coccyx, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible, palatine, inferior nasal concha, and hyoid
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).
