The first step of protein synthesis is called transcription. The DNA transcription to mRNA is actually the first step of the protein synthesis. During the transcription step the instructions encoded in the DNA of the genes are transcribed into the nucleotide sequence code of a ribonucleic acid (RNA)....
so your answer is Option (A)
Engulfing is what happens during endocytosis, a form of active transport that takes large molecules into the cell. During this process, the molecule is trapped inside a newly-formed vacuole. Hope this helps! :)
Lipids are made of three fatty acids bound to a glycerol molecule
According to the climate change, the correct order is :
<span>1 - Sources emit greenhouse <span>gases.
</span></span>CO₂ makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of CH₄ and nitrous oxide N₂O are also <span>emitted
</span><span>
2- </span>Global temperatures rise.
Temperatures measured on land and at sea for more than a century show that Earth's globally averaged surface temperature is rising<span>.
</span><span>
3- </span>Snow and ice melt.
If the surface temperatures warm above 32°, the snow and ice touching the surface will warm and begin to melt<span>.
</span><span>
4- </span>Sea levels rise.
When sea levels rise<span> rapidly, as they have been doing, even a small increase can have devastating effects on coastal habitats.</span>
Threatened species are species <span>which are vulnerable to endangerment in the near future.</span>
