Which of the following would cause an error in DNA replication?
A. DNA polymerase pairing A with G
B. DNA ligase connecting chunks of DNA
C. Helicase making a replication fork
D. DNA polymerase checking the DNA
Answer:
A. DNA polymerase pairing A with G
Explanation:
Adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).
DNA polymerase pairing A with G would cause an error in DNA replication. The correct option is A.
An error in DNA replication occurs when an incorrect nucleotide is inserted during the replication process.
DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.
It ensures the accuracy of replication by matching each nucleotide with its complementary partner (A with T and G with C).
If DNA polymerase pairs A with G instead of A with T, it results in a mismatched base pair.
This is considered an error in DNA replication since it introduces a mutation in the newly synthesized DNA strand.
The fidelity of DNA replication relies on the correct base pairing and proofreading mechanisms of DNA polymerase to minimize errors and maintain the integrity of the genetic information.
Thus, the correct option is A.

which of the following would be considered a healthy pattern of weight gain in a pregnant woman?
Answer:
Underweight women should gain 28 to 40 pounds. And overweight women may need to gain only 15 to 25 pounds during pregnancy. In general, you should gain about 2 to 4 pounds during the first three months you're pregnant and 1 pound a week during the rest of your pregnancy.
Which two phases do the chromosomes exist as chromatin (unraveled form of chromosomes)?
Answer:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
Explanation:
Answer:
Prophase is the first step of mitosis. This is when the genetic fibers within the cell’s nucleus, known as chromatin, begin to condense and become tightly compacted together. During interphase, the parent cell’s chromosomes are replicated, but they aren’t yet visible.

If someone adds thousands of small fish to a lake, how would the number of big fish?
If someone
ed
change?
Answer:
If in a particular lake, thousands of small fishes are added, then the number of the larger fishes will increase. The reason for this is because in general the larger fishes are feeding on the smaller fishes, thus with the introduction of the thousands of small fishes there will be an increase in their food source.

Explain how Enzyme A acts as a catalyst in the reaction. Be sure to include energy and time in your answer.
Answer:
Enzyme A acts as a catalyst by lowering the activation energy the reaction needs in order to take place this would in turn lower the reaction time of the reaction lading to a faster reaction. when conditions around the enzyme change this may lead to the breaking of hydrogen bonds causing the active site to change in shape, this change would would lead to the substrate no longer being able to fit which would lower the rate of reaction.
Explanation:
The process of evolution, or genetic change over time, has resulted in the wide variety of living things that exist today. What part do mutations play in the evolution of species
Answer:
Evolution has occurred thanks to many random changes in the DNA base sequence that we call mutations. This is caused by errors in the genetic information contained in the cells - due to chemical or physical factors - and also its subsequent propagation by replication, being transcendent for evolution those that will later be transmitted to the offspring: somatic cells if reproduction it is asexual and the gametes if it is sexual. For this reason, we say that mutations are the primary source of gene variability, essential for evolution to exist. Thus, without mutations, the genetic variability that natural selection needs would not be present - in addition, such diversity is important for the population to more successfully mold (or adapt) to continuous environmental changes.
Explanation:
A mutation is a change in the information contained in the DNA of cells. The DNA of an organism influences all aspects of its life. Therefore, a change in the DNA of an organism can produce changes in all aspects of its life. The mutation increases the genetic variability of the species and contributes to the adaptation of the species to the environment and to their evolution. Viability and fertility are associated with adaptation, the total capacity of an organism to survive and reproduce. The effect of a mutation in any generation is minimal, but over time a considerable amount of variation from mutations can accumulate. Most mutations are harmful and their carriers die, but those that produce an improvement remain in the species and are essential in the evolutionary process. When mutations appear in a certain population, the genotype changes from generation to generation, appearing individuals with characteristics different from those of their predecessors. This is how the population evolves, being able to originate new species. Mutations that are detrimental to the carrier individual will be eliminated by natural selection.

• sexual reproduction
• diploid
• unique daughter cells
• gametes
• meiosis
• unique
• haploid
• zygote
• identical daughter cells
• mitosis
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in sexual reproduction will have half of the genetic information of body cells and will be genetically unique. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a zygote: the first body of a new individual.
The new individual will now have cells that are diploid, meaning they have two sets of chromosomes. They zygote will have to do a lot of mitosis allowing it to grow quickly and ensure that all of its cells are genetically unique.
