Answer:
Explanation:
This question is incomplete however during DNA amplification using polymerase chain reaction, <u>the two primers attach to each DNA strand at the 3' end</u>.
Two primers are used during this process; one primer each for the two complementary strands of DNA (that run antiparallel to each other). The 5' end of each primer is attached to the 3' end of each DNA strand regardless of the direction the strand is running (5' to 3' or 3' to 5'). This process of attaching the primers to the DNA strand is known as annealing.
Answer:
organs are digestive system, respiratory, circulatory endocrine.
Explanation:
these systems helps to function in our body if the immune system is stronger to fight from diseases.
The structures present in an organism will allow the organisms to do certain things. if the organism has a vacuole then it will be able to store water.
Answer:
Explanation:
At the ending of pro phase or late prophase, the mitotic spindle begins to capture and organize the chromosomes.
* The chromosomes have finished condensing and are now very compact.
* The nuclear envelope is broken down and the chromosomes are released.
* The mitotic spindle grows more, and some of the microtubules start to “capture” chromosomes.
If the RNA is messenger RNA (mRNA), the process is called transcription. There are other types of RNA that are synthesized using DNA as a template, such as transfer RNA (tRNA) and ribosomal RNA (rRNA). Unlike mRNA, these are gene products, and the term "transcription" is not used when they are made.
