I think A but im not sure
Destructive interference occurs when waves come together in such a way that they completely cancel each other out. When two waves interfere destructively, they must have the same amplitude in opposite directions.
Answer:
dismissed the idea that species are constant and emphasized the importance of variation and change in populations
Explanation:
- Darwin and Wallace were the two scientists that contributed to the theory of evolution by natural selection.
- According to their ideas, the mechanisms that lead to evolution is natural selection.
- The idea for natural selection stems from the fact that the available resources are limited in nature and hence, there will be competition for survival and only the individuals that will have heritable traits that will favor their survival under such competition would be able to live and thus, produce more offsprings with similar traits and hence, this will lead to evolution.
- This theory of natural selection thus emphasized that the traits possessed by organisms are not constant but are variable and the populations constantly change over time.
Answer:
The question lacks options, the options are:
A) No proofreading will occur. B)The DNA will supercoil. C)Replication will occur via RNA polymerase alone.
D)No replication fork will be formed.
E)Replication will require a DNA template from another source.
The answer is D
Explanation:
Prior to division of any cell, its genetic material needs to be replicated. Ideally, in a bacterial cell, this replication starts at a particular nucleotide sequence called ORIGIN OF REPLICATION. An enzyme called DNA HELICASE then binds to the origin of replication and breaks the hydrogen bonds between the double-stranded DNA molecule to form a Y-shaped Replication fork, which serves as a template for DNA polymerase III to bind and begin to add nucleotides.
However, if a mutation occurs at a certain gene dNAb and alters the action of HELICASE enzyme. Thus, it prevents the helicase from separating the double-strands of the DNA molecule containing the gene. Hence, no replication fork will be formed and subsequently no template for DNA polymerase's action.
