234,607

The correct answer is -

4,403.

Gene can be described as segment of DNA (deoxyribonucleic acid), which codes for particular protein.

It is transcribed (that is DNA to mRNA) and translated (mRNA to Protein) to form a protein product.

There are total 4,403 genes that have been identified in the genome of E.coli.

Thus, option third is the right answer.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
