Answer:
Some organisms have a tremendous amount of noncoding DNA, like repetitive sequences.
Explanation:
DNA is the genetic material in almost all the living organisms but except in case of viruses that has RNA as their genetic material. DNA consists of the four nitrogenous bases, pentose sugar and phosphate group.
Prokaryotes have simple body organization and structure because of the sall amount of DNA. Eukaryotes have complex body organization because they have large amount of the transposons, repetitive sequences and non repetitive DNA sequences.
Thus, the correct answer is option (b).
Answer & Explanation:
People behave different when they exposed to the same stress or same physical activity. Although their heart rates are identical but every person's body function in a different way not in the same way. People handle the stress differently and they have different tolerance against physical activity.
So, people response against same stress or physical activity will be different to each other even though their resting heart rates same.
Answer:
d. Calvin cycle
Explanation:
During the light reactions or photochemical reactions of photosynthesis, chlorophyll molecules absorb sunlight and convert light energy into assimilatory power in the form of the electron carrier molecule nicotinamide adenine dinucleotide phosphate (NADPH) and the ATP.
The ATP and NADPH used as a source of energy to fix or reduce carbon dioxide into glucose.
The reduction of carbon dioxide to glucose occurs in the stroma of the chloroplast. The reactions of the conversions are called the Calvin cycle.
Gene mutation is a change in the nucleotide sequence, in a particular gene, whereas chromosomal mutation is a change in several genes, in the chromosome. ... Gene mutation is only a slight structural alteration, whereas chromosomal mutations are either numerical or structural changes in the entire DNA strand.
<u>Answer:</u>
<em>B. Many genetic diseases would be curable.
</em>
<u>Explanation:</u>
Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein. On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.
A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.
