DNA stands for deoxyribonucleic acid.
Where do we hypothesize that plants came from?
Inside our body, millions of nephrons in the kidney filter wastes in 2 steps. Each nephron has a glomerulus and a tubule. Waste filtering undergoes 2 steps:
First, fluid and waste pass through the glomerulus but, proteins, blood cells, and other large molecules are prevented from passing through. Second, the filtered fluid passes through the tubule wherein the filtered wastes are removed; minerals are sent back to the body, and the remaining output becomes urine.
Answer:
The correct answer is - A and D.
Explanation:
Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.
It is a result of the silencing of either maternal or paternal alleles in a pair. This occurs random and leads to phenomenon like X-inactivation. The mechanism involves methylation of the DNA to be silenced. paternal copy of UBE3A is silenced in neurons.
The correct option is mRNA.
mRNA stands for messenger RNA. For protein to be synthesized inside the cell, the genetic information inside the DNA has to be transcribed into the mRNA, which will move out of the nucleus and carry the information to the ribosomes. During the process of protein synthesis, the genetic information transcribed into the RNA will be used to produce new proteins.
