Pili are the filaments that help some bacteria stick to surfaces and exchange plasmids through conjugation.
Pili are hollow, hair like appendages that are found on the surface of some bacterial cells. Pili are composed of a special protein (known as pilin). Pilia act as a means of attachment of bacteria to surfaces (such as their host) and it is also used by bacteria to exchange their genetic material (plasmids) in the mating process between cells (known as conjugation).
Answer:
Step 1 of the formation of the solar system. the solar nebula collapses.
Step 2 of the formation of the solar system. rotating protostellar disk.
Step 3 of the formation of the solar system. center of nebula fusion begins, star is born.
Step 4 of the formation of the solar system
Explanation:
Answer:
The alignment of the elements in the following sequence will take place in the eukaryotic genome:
a. Promoter
b. Nucleotide to which methylated cap is added
c. 5 prime UTR
d. Initiation codon
e. Splice donor
f. Splice branch site
g. Splice acceptor
h. Stop codon
i. 3 prime UTR
j. Transcription terminator
k. Poly A addition site
After the process of splicing, the ultimate transcript will comprise the elements b, c, d, h, i. In eukaryotes, the RNA polymerase begins the process of transcription after it crosses the promoter region, and ceases at the transcription terminator. At the time of RNA processing, a 5 prime cap is supplemented to the transcript, splicing occurs, and a poly-A tail is supplemented. The 5 prime UTR and 3 prime UTR regions are found in the final transcript, that is, the mature RNA, however, are not translated.
