Answer: your answer is between c and b
Explanation:
Answer:
All progeny with heterozygous dominant genotype
Explanation:
Mendel crossed two pure breeding pea plants with respect to one genetic trait. He found that the F1 progeny obtained by crossing two pure breeding parent plants is always heterozygous dominant. The phenotype of the F1 progeny was always the phenotype of the dominant pure breeding parent plant.
For instance, purple flower color is a dominant trait over the white flower color in pea plants. When he crossed a pure breeding purple-flowered pea plant (PP) with a pure breeding white-flowered pea plant (pp), the F1 progeny was expressed the phenotype of the dominant parent and had purple flowers. The genotype of the F1 plants was Ww (heterozygous dominant).
Answer:
a. Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Explanation:
The correct answer is - a.Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Reason -
A fault is a fracture or zone of fractures between two blocks of rock.
Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.
During an earthquake, the rock on one side of the fault suddenly slips with respect to the other.
The fault surface can be horizontal or vertical or some arbitrary angle in between.
Answer:
<u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>
Explanation:
Transcription is the process in which DNA template is used to synthesize mRNA.
There are three steps of transcription:
It is the process in which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.
It is the process in which RNA polymerase moves along the DNA template and synthesizes mRNA. During this process, unwinding of double stranded DNA takes place.
As the RNA polymerase moves along the DNA template, it finally reaches a termination signal and then stops synthesizing. It is followed by the detachment of the newly formed mRNA and RNA polymerase from the DNA.
<u>QUESTION:</u>
- <u> A ribosome attaches to the initiation codon of a completed mRNA strand.</u>
This is the incorrect answer choice as this process does not happen in the process of transcription. This event happens<u> in the process of translation in which mRNA is used to synthesize proteins or amino acids. mRNA attaches to ribosome during this process.</u>
- <u>RNA polymerase moves along the template strand of the DNA creating an mRNA strand.</u>
This is the incorrect answer choice as this event takes place in the process of elongation.
- <u>A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.</u>
This is the<u> correct answer choice as this event takes place in the process of initiation of transcription</u>
- <u>The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.</u>
This is the incorrect answer choice. This event takes place in the event of termination of transcription.
Another name for unicellular organisms that dominated Earth up to the Precambrian time is prokaryotes. The correct answer is D.
