DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The three types of RNA are messenger RNA, transfer RNA, and ribosomal RNA.
A
true
B
false
Explanation: 

Detailed explanation-1: -Three main types of RNA are involved in protein synthesis. They are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). rRNA forms ribosomes, which are essential in protein synthesis. A ribosome contains a large and small ribosomal subunit.

Detailed explanation-2: -Three main types of RNA present in cells include messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA). Messenger RNA (mRNA) is a single-stranded RNA molecule responsible for carrying genetic information from the nucleus to the cytoplasm for protein synthesis by ribosomes.

Detailed explanation-3: -There are three types of RNA: mRNA, tRNA, and rRNA. mRNA is the intermediary between the nucleus, where the DNA lives, and the cytoplasm, where proteins are made. rRNA and tRNA are involved in protein synthesis. Additional RNAs are involved in gene regulation and mRNA degradation.
