Answer:
Transcribing the lacl sequence
Explanation:
lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.
However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.
A good night's sleep improves recall to the previous day's events by facilitating the transfer of memories from the cerebral cortex. Sleep makes you feel better, however, its important is way beyond boosting the mood or banishing under eye circles. Adequate sleep is a key part of a healthy lifestyle, and can benefit the heart, weight, and mind among others. It improves memory, also curbs inflammation which is linked to heart disease, stroke, diabetes, arthritis, and premature aging, among other benefits.
Answer:
Molten rock and associated fluids. Environmental changes. Surface water. Gem formation in the Earth's mantle.
The answer is 23.
A human being receives 23 chromosomes from each parent. So each human has 46 chromosomes. Chromosomes X and Y determines your sex.
