Answer:
Facilitated diffusion involves transport protein
Explanation:
Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.
Explanation:
Answer:
Autotrophs. An organism like a green plant that can make its own food are called an autotrophs. Autotrophs can make their own food through the process of photosynthesis. Photosynthesis is present in these organisms, a mechanism where they gather, water from the soil, heat from the sunlight though the pigment called chlorophyll and carbon dioxide in the air to manufacture and generate its own food. Autotrophs are also the primary sources of food in the food chain which contains immense amount of calories.
Explanation:
Answer:
miR-223 inhibits the expression of the fibroblast growth factor (bFGF) gene, and thereby ESCs cells maintain their undifferentiated state
.
Explanation:
Non-coding RNA (ncRNAs) are molecules that regulate gene expression, thereby playing important biological functions in cell differentiation, cell cycle, apoptosis, etc. MicroRNAs (miRNAs) are a type of ncRNAs capable of controlling gene expression patterns by regulating mRNA stability and by suppressing their translation into proteins. It has been shown that miRNAs function by imperfectly base-pairing with the 3′ UTR of target mRNAs (Pillai et al. 2005).
