Answer:
U-U-A
Explanation:
A mRNA molecule is formed as a result of transcription, which then proceeds to the ribosomes in the cytoplasm to undergo translation. Translation is the process whereby an amino acid sequence (protein) is synthesized using the information in the mRNA molecule/sequence. The mRNA sequence is read in a group of three nucleotide bases called CODON. Each codon specifies an amino acid.
This codon is read by another RNA molecule in the ribosome called tRNA (transfer RNA). tRNA contains another set of three nucleotides called ANTICODON, which is complementary to the CODON and responsible for reading the codon in order to carry the corresponding amino acid to the growing sequence.
According to this question, a portion of a messenger RNA molecule contains the base sequence A-A-U, the complementary anticodon sequence of the tRNA would be U-U-A.
Answer:
DNA digestion was not complete.
Explanation:
When a particular DNA needs to be used for the experiment, it is firstly processed by restriction digest. A restriction digest is a procedure for DNA preparation for further examination and manipulation. It is defined as a technique used for separating DNA fragments. This separation is being done using specific enzymes that will bond to specific sites and locations to the DNA so all DNA fragments will be a similar size. These enzymes are called restriction endonucleases or restriction enzymes and are extracted from bacteria for this particular cause. Once fractured or digested, DNA fragments may be amplified by PCR (polymerase chain reaction) and used for further experimentation.
When DNA is sequenced, all recognition sites (on enzymes) are visible and detectable. However, if an extra recognition site is found after sequencing, it means that initial mapping was not completed (assuming the DNA sequence has no errors). Initial restriction digestion was not completely done, so DNA is stuck in the middle of the process, in various degrees of supercoiling and digestion.
Everything. DNA contains genes and which genes a person has determines which (if any) proteins are formed. Based on how much of a protein is formed determines how strong a trait is expressed
The correct answer is delirium.
The Confusion Assessment Method (CAM) is a psychiatric tool used to assess and identify delirium in patients. According to the first observations and the patient's responses to CAM, the nurse can conclude that the patient exhibits signs of delirium. This is because he is unable to concentrate and organize his thinking, he is inattentive, he is lethargic and all these behaviours are sudden and acute. These symptoms cannot be associated with dementia, as dementia develops gradually and doesn't affect attention and consciousness. Also, the symptoms don't point to depression since depressive patients are focused and attentive. Finally, the nurse cannot conclude that the patient is dehydrated because further tests need to be conducted to assess hydration.
C. adaptation is a direct result of natural selection
