During the process of chromosome replication, A genetic error occurs. As a result, a sequence of events occurs as described belo
w. Event A. Protein with the new sequence of amino acids is produced. Event B: a DNA strand with an altered base sequence is formed. Event C:, A new inheritable trait is expressed in an organism. Event D, An mRNA strand with the new sequence of bases is synthesized. The usual order in which these events would occur is: 1. B-D-A-C. 2. B-D-C-A. 3. D-A-B-C. 4. D-C-B-A
Explanation: If a genetic error occurs during chromosome replication, it will lead to a series of events ranging from:
1) Production of a DNA strand with an altered base sequence.
2) Production of an mRNA strand with an altered base sequence during transcription. This is because mRNA is synthesized by copying the genetic message coded in the DNA.
3). Synthesis of a protein with an altered amino acid sequence during translation, and this eventually leads to
4). The expression of a new inheritable trait in the organism.
It forms from sandstone that has come into contact with deeply buried magmas. Quartzite looks similar to its parent rock. The best way to tell quartzite from sandstone is to break the rocks. Sandstone will shatter into many individual grains of sand while quartzite will break across the grains.
Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.
The principle is called CEPHALOCAUDAL PRINCIPLE. This principle proposed that growth follow a particular pattern in which the head and the upper part of the body grow first before the growth proceeds to other part of the body.
<span>Meiosis helps prevent mutations from occuring over and over again.
In Meiosis process, the number of chromosomes during reproduction was caused in half.
During this process, the chromosomes that could potentiall caused mutation could be tossed out and therefore reduce its chance from happening</span>
