Specimens taken from a patient sample usually contain a mixture of different bacteria. But sample with only one type of bacteria, are necessary to study a bacterial species accurately. Therefore, it is necessary to isolate all of the possible disease causing organisms in order to study the sample by itself. Once isolation of individual colonies is done, then these colonies can be used for identification tests. A sample of the specimen is move very fast onto an agar plate in order to physically separate the bacterial colonies.
I believe the correct answer is B. Nephridia are excretory organs. They are organs found in invertebrate animals that are present in pairs and are responsible for performing functions that are similar to the kidney of a vertebrate. They excrete wastes from metabolic processes.
Answer:
B
Explanation:
Its not A or C bc there is no thymine in a RNA strand. Its not D bc it doesn't match the complementary DNA strand.
DNA Polymerases type of enzyme ensures that the correct base for growing the chain is aligned with the template chain.
<h3>What is DNA Polymerase?</h3>
- The family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the basic building blocks of DNA, includes DNA polymerase.
- These enzymes, which are required for DNA replication, typically function in groups to divide an initial DNA duplex into two identical copies.
- DNA polymerase "reads" the pre existing DNA strands throughout this process to produce two new strands that are identical to the preexisting ones.
- Deoxyribonucleotides, the components of DNA, are synthesized by DNA polymerase as its primary purpose.
- The nucleotides and bases found on each strand of the original DNA molecule are paired to form the DNA copies.
- This coupling always occurs in certain pairings, with cytosine and guanine constituting one pair and thymine and adenine forming the other.
- RNA polymerases, on the other hand, create RNA from ribonucleotides that are either found in RNA or DNA.
