Answer:
A
Explanation:
because each of the nitrogenous bases can only pair up with one of the other bases.
MRNA is transcribed from DNA and carries information needed for protein synthesis. During the translation phase of protein synthesis, the tRNA carry specific amino acids the the ribosome, and rRNA plays a role in the synthesis of the ribosome which is the site of translation phase of protein synthesis.
During meiosis i, the Kinetochores for each pair of sister chromatids of each homologue, attach to microtubules from the same pole.
<h3>What is Kinetochores ?</h3>
Large protein structures called kinetochores link chromosomes to the microtubules of the mitotic and meiotic spindles to transfer the replicated DNA from a mother cell to its daughters.
- Its primary role is to stabilise the spindle's microtubules so that, during metaphase, the chromosomes may align correctly at the metaphase plate before being pulled toward the opposing poles of the cell during anaphase. In order to ensure appropriate chromosome segregation, the kinetochore is crucial.
- Each chromosome binds to microtubules from just one spindle pole, and each pair of homologues does so from the other pole. In order to be separated during metaphase I, homologous pairs rather than individual chromosomes line up at the metaphase plate. stages of meiosis type I.
