It melts into a tail and vanishes
Answer:
a, b, c are correct
Explanation:
Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.
Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.
Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.
There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.
Therefore, the correct options are (a), (b), and (c).
The right answer is false.
Lobotomy is a brain operation that cuts or alters the white matter of a brain lobe. It is now banned in many countries and is no longer considered a good practice in today's medicine.
The lobotomy was performed in psychosurgery with the aim of interrupting certain neural circuits to treat mental illnesses, schizophrenia, epilepsy and even chronic headaches before declining in the 1950s with the advent of the first neuroleptics.
They Increase the surface area available for the absorption of nutrients
Answer:
The human body is able to synthesize them: proteins, fats
Contains nitrogen in the amine group
: proteins
Made according to instructions from DNA: proteins
Explanation:
The cells of the human body synthesize proteins from the transcription and translation processes.
Fats and carbohidrates are ingested in the diet and metabolized by the body. However some types of fat such as cholesterol is synthesized by the human body. Same as phospholipids that are part of the membranes.
Proteins are formed by hydrogen, oxygen, nitrogen and carbon. Amino acids are characterized for owning a carboxyl group (-
COOH) and an amino group (-NH2)
