The easiest example is of Pentadactyl limbs. This is the 5 bone structure of the 'arm' of different animals being similar, contributing to the explanation of common ancestors. Animals that have this are whales, horses, dogs, cows, birds and even humans. We each share the same five bones in similar places but with some of them changed to suit certain functions ie birds are more spread to support flying, while humans are made for throwing, picking up and holding things.

There
are three principles to keep in mind when predicting the sequence of
the mRNA produced by transcription of a particular DNA sequence.
The RNA polymerase reads the sequence of DNA bases from only one of the two strands of DNA: the template strand.The
RNA polymerase reads the code from the template strand in the 3' to 5'
direction and thus produces the mRNA strand in the 5' to 3' direction.In
RNA, the base uracil (U) replaces the DNA base thymine (T). Thus the
base-pairing rules in transcription are A→U, T→A, C→G, and G→C, where
the first base is the coding base in the template strand of the DNA and
the second base is the base that is added to the growing mRNA strand.</span>
Yes this is true sort of like when light rays pass through water particles in the atmosphere and create a rainbow :)
