Ans.

Lysozymes are hydrolytic enzymes, synthesized and secreted by various organisms as a defense mechanism against bacterial infections. Invertebrates show type-i lysozymes (invertebrate lysozyme).

Lysozyme kills gram-positive bacteria by breaking bacterial cell walls as it prevents polymerization of components, required for cell wall synthesis. Invertebrates do not have immune cells, such as T cell, B cells, and natural killer cells.

Thus, the correct answer is 'option b). enzymes such as lysozyme break down the cell walls of harmful bacteria.'

"Interphase refers to all stages of the cell cycle other than mitosis. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin.

Some molecules found in foods are known to be capable of driving DNA methylation or DNA demethylation. For example, folic acid (

Rufina [12.5K]

Answer: Eating excessive quantities of such molecules could deregulate this process, increasing methylation and repressing the expression of genes that should normally be expressed.

Explanation:

DNA methylation is one of the epigenetic mechanisms involved in the regulation of gene expression, because it is a process by which methyl groups are added to DNA.

Methylation then modifies the function of DNA when it is found in the promoter gene, it is essential for normal development and is associated with a number of key processes, including genomic imprinting, inactivation of the X chromosome, repression of repeating elements, aging, and carcinogenesis. Usually, it acts to suppress gene transcription.

For example, folic acid is essential for the rapid cell division that occurs during early fetal development and it also plays an important role in methylation and thus in gene regulation. The metabolism of these vitamins is aimed at achieving adequate levels of DNA methylation, necessary for the cellular processes. Eating excessive quantities of such molecules could deregulate this process, increasing methylation and repressing the expression of genes that should normally be expressed.
