|
RNA contains uracil
|
|
|
RNA can only be found inside the nucleus
|
|
|
RNA is single stranded
|
|
|
RNA contains genetic information

Detailed explanation-1: -Thus, although all types of RNAs are synthesized in the nucleus, only hnRNA is found in the nucleus. The correct answer is D.
Detailed explanation-2: -It is formed after transcription. It undergoes additional processing to form mRNA and is then transported out of the nucleus for translation. Hence hnRNA is only found inside the nucleus.
Detailed explanation-3: -Ribosomal RNA (rRNA) is the most common form of RNA found in cells – it makes up around 50% of the structure of the ribosomes. It is produced in the nucleus, before moving out into the cytoplasm to bind with proteins and form a ribosome. Transfer RNA (tRNA) is found in the cytoplasm and has a complex shape.
Detailed explanation-4: -RNA does not have double stranded -helix structure.
Detailed explanation-5: -RNA is found in the cytoplasm but it is synthesized in the nucleus. It is then transferred through the body. The DNA has the genetic code which makes the RNA and RNA contain the code to make the primary sequence of the amino acid to make proteins. Thus the option (B) and (D) are true statements about RNA.
