Vedclass · Answer

(C) Lampbrush chromosomes are large chromosomes found in the oocytes of many vertebrates and invertebrates. They possess lateral loops that are sites of intense $RNA$ synthesis,making them transcriptionally active.Informosomes are complexes of $mRNA$ and proteins found in the cytoplasm of eukaryotic cells,particularly in oocytes. They serve as a storage form of $mRNA$ that is translated later during development. However,the statement that they can be used in the future for embryo development is scientifically vague and not a standard biological fact in this context. Therefore,the Reason is considered incorrect or irrelevant to the Assertion.

$A$: Lampbrush chromosomes show transcriptionally active loops.
$R$: Informosomes can be used in future for embryo development.
