Answer:
The correct answer would be A) ribosomes.
A ribosome is a vesicular structure present in both prokaryotic and eukaryotic cells. They consist of ribosomal RNA and associated proteins.
They are the site of translation in both prokaryotic and eukaryotic cells.
They are made up two units which are called large sub-unit and small sub-unit.
In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.
In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.
The cycle that is described in the problem is called the water cycle. in this cycle, the water from a lake is evaporated through the heat of the sun and the water is accumulated in the clouds. When the clouds are saturated, then water condenses and precipitates to fall as rain.
The answer is D) codes for a specific trait . Hopefully its right.
<h2>Answer:</h2>
The mRNA is important for carrying the sequence information of amino acid in poly peptide chain. While tRNA carry the specific amino acids from cytoplasm to the poly peptide chain according to the message in mRNA.
<h3>Explanation:</h3>
- mRNA is the message from the DNA in the form of specific nucleotide sequence.
- mRNA is complementary sequence of nucleotide formed in the process of transcription in nucleus.
- While tRNA are also produced in the nucleus from the DNA but they do not contain any message for the poly peptide production. While they are transported to cytoplasm and their function is the transport of amino acid from cytoplasm to growing poly peptide chain.
The basic difference between light and electron microscope is their application in visualizing specimen.
