Sedimentary, because of the glaciers that once covered Indiana they lithified which is a part of the rock cycle in the sedimentary division.
Answer:
The correct answer is option A. "V(D)J recombination is similar to the replicative transpositional mechanism".
Explanation:
V(D)J recombination and the replicative transpositional mechanism are very different biological processes. V(D)J recombination is an unique mechanism that takes place by somatic recombination and results in the highly diverse repertoire of antibodies. On the other hand, the replicative transpositional mechanism takes place when a transposable element is duplicated during replication.
Answer:
Answer;
A specific sentence.
If a chromosome is like a book, then a gene is like a specific sentence.
Explanation:
A chromosome is a structure that is made of a chemical known as deoxyribonucleic acid, or DNA as well as protein. Chromosomes are found in the nucleus of cells. Chromosomes contain many genes. A gene is a molecular unit of heredity, it is a segment of DNA that provides the code to construct a protein.
Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitos
<h2>Question no.6:</h2><h3>Answer:</h3>
The correct answer is <u><em>option B which is there 25% chances of having the pomp disease.</em></u>
<h3>Explanation:</h3>
According to the given information given in question both the Julia and her husband are carriers. Due to which there are three genetic probabilities of their child:
- Normal kid with both healthy alleles: 25%
- Carrier healthy child with one healthy and one defective gene: 50%
- Child with pomp disease having two defective genes: 25%
<h2>Question No. 7:</h2>
The correct option is <em><u>A which is symptoms will appear before the age of nine months.</u></em>
<h3>Explanation:</h3>
In this disease, there is low production of an enzyme acid α-glucose, which degrades lysosomal glycogen. In the absence of enzyme lysosomal glycogen accumulates and results in the weakness of muscle especially related to breathing. This leads to early onset of disease symptoms and early death usually in infancy in case of having both defected genes.
<h2>Question No. 8:</h2><h3>Answer:</h3>
- The DNA of chromosome no. 17 of a normal person has a gene GAA and the pomp offspring will have the defected gene. Like the nucleotide sequence of the gene will be changed.
- At cellular level in pomp, there will be an accumulation of lysosomal glycogen.
- The muscles which are involved in breathing do not work properly leading to low breathing rate or completely blocking the respiration.
- This is a genetic problem which can not be fixed.
- There is no cure for this disease because it affects intracellular metabolism which is not easy to cure by enzymes supplements.
