How mutation occurs on replicated DNA molecules​

Biology

Answer:

When strand slippage occurs during DNA replication, a DNA strand may loop out, resulting in the addition or deletion of a nucleotide on the newly-synthesized strand. ... But if this does not occur, a nucleotide that is added to the newly synthesized strand can become a permanent mutation.

Answer:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

I hope it's helpful!

What is true of saturated fatty acids?
Misha Larkins [42]
Saturated fatty acids are 'saturated' with hydrogen meaning they contain the maximum number of hydrogen. This causes them to be straight on the molecular level, allowing them to be packed close together other saturated fatty acids. Thus, they tend to be solids at room temperature. Examples of saturated fats are butter and the solid white fat you see on raw meat.

When will chloroplasts be aligned with their flat surfaces parallel to the walls in mesophyll cells? When will they be perpendic
padilas [110]

Answer:

Flat surface parallel to mesophyll walls  position

Chloroplast assumed this position  in condition <u>of low  light intensities or optimum light intensities</u>   for the reception of maximum amount of incident light. necessary for photosynthesis

Perpendicular to the incident light position.

During condition of <u>extreme high light intensit</u>ies chloroplast  aligned in this position to avoid the loss of electrons from the chlorophyll from absorption of photons; (PHOTOXODATION.)  

Basically photooxdation is a wasteful process which destroys the plants.
