Imagine that a eukaryotic cell carries a mutation that causes the poly(a) tail to rarely be added to the primary transcripts. The result of such a mutation will be the primary transcript would likely be less stable, and its transport from the nucleus to the cytoplasm would be affected.
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
While most mutations are benign, some can be detrimental. A dangerous mutation may lead to a cancerous condition or possibly a genetic problem. Chromosome mutations are yet another type of mutation. The tiny, thread-like structures known as chromosomes, which are found in the cell nucleus, carry genes.
Genetic mutations, which occur as your cells divide and generate duplicates of themselves, are modifications to your DNA sequence. Your DNA teaches your body how to develop and work. Genetic changes may result in diseases like cancer or, in the long run, may enable people to adapt to their environment more successfully.

Only males can be carriers for X-linked recessive traits, False, it should read "Only females can be carriers for X-linked recessive traits."
<h3>What is an allele in a gene?</h3>
An allele is defined as an allele is a variant form of a gene.
For example, if both of your parents have green eyes, you might inherit the characteristic of green eyes from them.
Or if your motherhas freckles, you might have freckles too because you inherited the characteristic for freckles
Thus, option "A" is correct.
