In coding regions of the genome, unless the length of an indel is a multiple of 3, it will produce a frameshift mutation. For example, a common microindel which results in a frameshift causes Bloom syndrome in the Japanese population. Indels can be contrasted with a point mutation.
reverberate If you give a loud shout in a cavernous place, like a gym or a church, the sound of your voice will reverberate throughout the room. Reverberate means sound waves traveling back and forth, as in an echo. Often we use reverberate to talk about sound, or sometimes light. If a noise echoes for a long time, we can say the space reverberates with that noise. You may have heard of a reverb effect in audio processing, which is basically a long echo. We also use the word metaphorically to describe the impact of huge events.
To quantitatively characterize the reverberation, the paramater called the reverberation time is used. The sketch below depicts the sound received by a single listener as a function of time as a result of a sharp sound pulse some distance away. The direct sound received is followed by distinct reflected sounds and then a collection of many reflected sounds which blend and overlap into what is called reverberation.
