In order to start DNA polymerase from scratch, the primase produces brief strands of RNA that attach to single-stranded DNA. Since the leading strand can only be replicated continuously in the 5' to 3' direction, this enzyme does not operate in any other orientation. Short Okazaki fragments are produced and subsequently joined together during lagging-strand replication.
DNA copies itself through a semi-conservative process known as DNA replication. The S Phase (synthesis phase) of the cell cycle is when DNA replication takes place. To guarantee that both dividing cells have a copy of the DNA in their nuclei, DNA replication must take place before a cell splits. DNA replication enzymes support the replication process. Two DNA strands comprise each DNA molecule. DNA has a double helix form, which resembles a twisted ladder. Replication of DNA occurs in a semi-conservative manner. Each daughter strand created when DNA is duplicated contains (conserves) one of its parent strands.
DNA helicase, RNA primase, DNA polymerase, and DNA ligase are the enzymes that are involved in DNA replication in that sequence. DNA helicase, an enzyme, assists in the double helix's unraveling during the replication process. A signal is subsequently sent to the enzyme DNA polymerase by RNA primase, which then creates an RNA primer on the parent strand. To create two new daughter strands of DNA, DNA polymerase then adds complimentary nucleotides to the parent strand. DNA ligase binds the Okazaki fragments together to create a new daughter strand of DNA once all bases have been paired with their partners (adenine with thymine and guanine with cytosine).

To rule the vast territory, the Qin instituted a rigid, authoritarian government; they standardized the writing system, standardized the measurements of length and weight and the width of highways, abolished all feudal privileges, oversaw large-scale construction of what then became the first Great Wall.
Answer:
Save the Children's work saves and improves children's lives around the world. We work to ensure children have healthcare, food and shelter, as well as learning and child protection services when children need it most.
Answer:
In this experiment, the independent variable is the participant either being alone or in a room with others.
Explanation:
In a study like the one described in the question, the dependent variable is what is being measured by the study. In this case, the dependent variable is people's level of anxiety.
<u>The independent variable is something that is changed or controlled in order to affect the dependent variable</u>. In this case, Priya is controlling the environment. Some participants are interviewed alone while others are interviewed in small groups. She wishes to see how the environment will affect their level of anxiety. T<u>herefore, the independent variable is being alone / being in a group.</u>
This process is best described by the concept of: self-fulfilling prophecy
