The toxic condition characterized by retention of nitrogenous substances in the blood is called uremia.  Uremia is a toxic condition caused by retention in the blood of nitrogenous waste products normally excreted in the urine.  Acute renal failure denotes a sudden onset of renal failure, such as that caused by an accident, certain drugs or poison. The kidneys may recover or the damage may be permanent. If the kidneys stop functioning this condition is what they called uremia, therefore the body is full of  extra water and waste products, leading to swelling in the hands or feet, fatigue and weakness. End-stage renal disease refers to when the kidneys have lost all or nearly all function.

Which of the following are important features for transcription?
devlian [24]

Answer:

The correct answer will be option-A and B.

Explanation:

Transcription is a process which synthesizes a complementary molecule of DNA which acts a messenger called RNA.

The gene contains a sequence of the nucleotide at the beginning of gene called promoter sequence. The promoter sequence has the ability to attach an RNA synthesizing enzyme called RNA polymerase.

The RNA polymerase is the enzyme which synthesizes the RNA molecules using a single strand of DNA called template strand.  RNA polymerase binds nucleotide at 3' end of the strand thus proceeding the strand in 5' to 3' direction.  

The promoter and RNA polymerase begins the process of transcription and thus option-A and B is the correct answer.

  • Hominis were the first human to appear on the surface of the earth.
  • This was in the Miocene epoch which was about 6 million years ago.
  • Compared to the age of the earth, this time lapse is very small and not up to 1%.

Aleks [24]
The correct answer is A.
The use of antibacterial drugs can cause modifications in the genetic material of the concerned bacteria. If the genetic material of the bacteria are modify, that means they have undergone mutation. Because the base sequence of the normal and that of the mutated gene is different, antibiotic will not be able to recognize the bacteria again and thus will not be able to attack it.
