Answer:
The correct answer is A.) during transcription
Explanation:
The pairing during DNA replication and transcription is a little bit different. During replication, A pairs with T, T with A, C with G, and G with C. In transcription T is replaced by U so when there is nucleotide adenine is present in the DNA sequence than uracil will be added against it as complementary nucleotide in mRNA during transcription.
So here 5'-GAT-3' nucleotide sequence is present in DNA and after transcription the nucleotide sequence will be 5'-CUA-5' because U is added against A during transcription. Therefore the correct answer is A.
The order of steps for the digestion of proteins will be;
In mechanical digestion, the teeth grind food and break it in to smaller parts.
Churning and the enzyme pepsin break down protein in the stomach
The pancreas releases enzymes trypsin and chymotrypsin
Tryspsin and chymotrypsin act on the proteins to break them down in the duodenum
Amino acids are absorbed by the capillaries in the Jejunum and lastly
The amino acids enter the blood stream and are circulated throughout the body.
<span>Yes, both prokaryotes and eukaryotes have liquid cytoplasm in their construction. To the best of my knowledge, AT LEAST MOST viruses do as well, if not all. However, their cell structures are relatively primitive and their cytoplasm is viscous and granular.</span>
Answer:
<h2>They provide a 3’ end for the DNA polymerase.</h2>
Explanation:
Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.
Polymerase chain reaction was invented by Kary Mullis in 1983.
Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.
