In a double standard deoxyribonuclic acid denoted as dsdn, which looks like this in a step ladder form, runs in anti -parallel direction.
00:14
That is the first strand runs from 3 -dash to 5 -dax direction.
00:18
And its opposite strand runs from 5 -dash to 3 -dash direction.
00:22
Now the first strand, which is seen here, is known as the sense strand.
00:29
This is because they do not get transcribed to produce a messenger rna.
00:36
While this strand is the template stand or the antisynce stand.
00:45
Now these gets transcribed to produce a messenger ribonuclic acid denoted as mrna.
00:55
This do not produce a mrna.
00:58
Now if we see if in this antisynstrand, if any mutation that happens, that is if a guanine diploid denoted as g is replaced for a thymine nucleotide denoted as t, then this type of mutation is known as point mutation.
01:21
Now suppose if in a point mutation, the amino acid that has to be translated at the end of the process gets changed or do not get changed, that is no change in the amino acid, denoted as a a or denoted as a .a.
01:49
If the amino acid gets changed or no change happens in amino acid also, there will not be any change in the protein that is going to be produced...
