When organic molecules decompose, energy is released.
Remainder of question from another source:
What are the steps in the shotgun approach to whole-genome sequencing?
PLACE IN ORDER
A. 1-kb fragments are cloned into plasmids.
B. Chromosomes copies are broken into 1-kb fragments
C. The plasmids are sequenced.
D. Multiple copies of the same chromosome are prepared.
E. A computer combines the fragments sequences.
Answer:
DBACE
Explanation:
First, multiple copies of an entire chromosome are created (D). Then, the chromosome is fragmented into lots of pieces approximately 1kb in length. These pieces will contain overlapping sequences (B). Next, the newly created 1kb fragments will be cloned into plasmid vectors (A). The plasmids containing the DNA fragments are then sequenced (C), and the sequence is combined and aligned by a computer, aided by the fact the fragments are overlapping (E).

Answer:
Super-repressor (Is) - Uninducible dominant
Binding region is modified by the protein called repressor which prevents the lactose to bind with it. Thus, even the lactose is present the repressor protein is bound to the promoter and can not be detach from it. Transcription is not inducible.
Promoter mutation (P)- - Uninducible recessive
Mutated promoter region inhibits the binding of RNA polymerase that leads to trranscription.
The lacZ gene (
Z-) is mutated - recessive while the normal LacZ gene (Z +) - dominant
.
Inducible (Wild type) No expression (Mutant)
F' lac+/ Is No Yes
F' lac + / P- Yes No
F' lac + / Z- Yes No
F' lac +/ Mutation1 Yes No
F' lac+ / Mutation2 No Yes
Mutation 1 and F' plasmid - Inducible wild type
Mutation 2 and F' plasmid - Mutant no expression
Answer: Autocrine signal, paracrine signal and endocrine signal.
Explanation:
Testosterone is an example of hormone which shows its effect on different locations of the cells.
The autocrine signal can be defined as the siganals which shows its effect on the cell from where it is being produced. This means a cell targets itself.
Then comes the paracrine signals in which signals acts locally on the cells nearby it. The cells close together to the cells producing chemical signals is being affected.
The endocrine signals can be defined as the effect of the hormone on the distant cells. The signals is produced by the cells somewhere else but is carried through the bloodstream to the distant cells.
All of the three effects is being shown by testosterone autocrine, endocrine and paracrine.
