Liono4ka [1.6K]

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.

Describe the chemical components of DNA.
Slav-nsk [51]

DNA is composed of nucleotides, which are composed of three parts:

1. A five carbon carbohydrate (pentose)

Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by (CH_{2} O)n. They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)

2. A nitrogenous base

Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines

The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.

The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.

3. One or more phosphate groups

A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by (PO_{4} ^{-3}).
