D. an RNA molecule since the RNA molecule contains information for making proteins
Answer:
Period of the waves = 0.00013 s (Approx.)
Explanation:
Given:
Propagation speed = 150 m / s
Wavelength = 0.02 m
Find:
Period of the waves
Computation:
Period of the waves = Wavelength / Propagation speed
Period of the waves = 0.02 / 150
Period of the waves = 0.00013 s (Approx.)
Answer:
b. methylation.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
Hence, DNA regions that are transcriptionally silenced by hypercondensation have often undergone a modification of their cytosine residues termed methylation.
For example, CpG island methylation transcriptionally silences about 650 to 800 genes in patients suffering from colorectal cancer.
Answer:
Kerb cycle
<u>Explanation</u>:
The result from mitochondria is ATP, that acts as a currency of the energy in the cell. In the cytoplasm of mitochondria kerb cycle occurs. In this process it has several other process, once it uses acetate and water to give NADH from NAD+ and gives carbon dioxide as waste. The NADH formed is fed by oxidative phosphorylation or electron transport. The outcome of these processes is oxidation of nutrients to give chemical energy in ATP form.
The neuron releases chemical messengers. Otherwise, there would be no 'signal transduction' in the postsynaptic cell. So, your answer is B.
