Common Symptoms. 1  Changes in Fetal ActivityBy the time your babyâs head is engaged in your pelvis, heâll have a lot less room for any more than a twist or squirm. 2  Pelvic PainIf your babyâs head is pressing into your pelvis, hips and bladder, youâll feel more pressure as the week wears on.
The significance of a DNA is very high. The gene's sequence is like language that instructs cell to manufacture a particular protein. An intermediate language, encoded in the sequence of Ribonucleic Acid (RNA), translates a gene's message into a protein's amino acid sequence. It is the protein that determines the trait. This is called central dogma of life.
Proteins are composed of chains of amino acids. Today, we can analyze a protein product to find out the sequence of amino acids that goes into it. The sequence of amino acids found in a protein is itself the result of the translation of another sequence, a sequence of bases in DNA. There are three bases in the DNA for each amino acid in the protein. This means that comparisons of DNA sequences are finer-grained than comparisons of protein sequences, and can resolve finer differences. The ability to derive sequences of DNA is a more recent development than being able to sequence a protein.
