Answer:
Hello! Here are the answers:
- Chromosomes are a highly condensed form of a combination of DNA and protein called chromatin. DNA strands (negatively charged) are tightly wound around these proteins called histones (positively charged) to form chromosomes.
- Mechanism genes code for for proteins that govern life processes. These genes or portions of DNA are called exons. DNA segments between these exons are called introns that strictly code for regulatory proteins and also contain genetic regulatory elements (DNA sequences that control gene expression).
- Gene expression is the process of translation of DNA sequences into proteins. The genetic code is the nucleotide sequence in the DNA itself that codes for different amino acids that combine together to form a functional protein.
Explanation:
* 2. The intronic regions are misleadingly referred to as "junk DNA" but introns code for crucial regulatory elements that control gene expression.
* 3. The genetic code determines the sequence of amino acids in various proteins.
Answer:
Option-A
Explanation:
Penicillin is an antibiotic drug that is derived from the fungal species of Penicillium molds especially the<em> Penicillium notatum</em>. The penicillin acts by disrupting the formation of the cell wall and thus prevents the growth of the bacteria.
The discovery of penicillin was accidental when he was studying the petridish of staphylococcus and he found that due to avoidance while the experiment, molds grew in the petridish. The area around the mold was clear and clear rings without the bacteria were easily observed. This lead to the discovery of the penicillin compound.
Thus, Option-A is the correct answer.
