During replication, enzymes called ____________________ untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the _______________________.
Answer:
During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.
Explanation:
Replication is the process of multiplication of DNA molecules where, from one molecule, two molecules with the same information as the original can be obtained.. Each new replicated DNA molecule has an original strand and a new strand, so replication is semi-conservative.
For replication to occur, the double strand of DNA must be separated, a process that requires the participation of a group of enzymes called helicases. The helicases are responsible for breaking the hydrogen bonds between the complementary bases of one strand and another.
The DNA strands, when separated, form a zipper-like image, and the point of separation between the two is called the replication fork.
The study of genes is called genetics.
The correct answer is During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.

Please explain how cellular respiration and photosynthesis are considered opposite processes. Do not tell me on how the equations are reverse of each other, that is not what I am looking for.
Answer: when the 6CO2 and the 6H2O in photosynthesis go in and they break up in to partials and they change and form in to 6O2 and C6H12O6, and then when the 6O2 and the C6H12O6 go in to cellular respiration and they do the same thing only 6CO2 and 6H2O comes out and the process start all over again.

Which is a non-Mendelian trait?
A. A trait controlled by many genes
B. A trait with a clearly dominant form
C. A trait controlled by one gene
D. A trait with two alleles
Answer:
The answer would be A.
Explanation:
Non-Mendelian traits are traits that are not passed down with dominant and recessive alleles from one gene. Examples of polygenic traits are hair color and height. ... Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.
A non-Mendelian trait would be a trait that is controlled by many genes. The right option would be A.
Mendelian traits are traits that obey the principles of the Mendelian laws While non-Mendelian traits simply do not conform with the principles and laws of Mendel.
A trait that is Mendelian would have the following:
Show simple dominance or recessive formControlled by a single geneEach gene must have 2 alleles. The 2 alleles can be the same (homzygous) or different (heterozygous).Thus, a trait that is controlled by many genes is clearly a non-Mendelian trait.

Basically, the individual organisms in an ecosystem forms a population and this also gives rise to a community. This ultimately implies that, the ecological levels of organization are ranked in ascending order as follows:

In order for protein synthesis to occur, both transcription and translation must occur. Which of the following statements describes the difference between transcription and translation?
In transcription, the genetic code of a DNA molecule is encoded. Translation is the process of converting the DNA code into a code that RNA can use.
In transcription, an amino acid chain is encoded in a DNA molecule. Translation is the process of turning the amino acids into nucleic acids in an RNA molecule.
In transcription, a double helix DNA molecule is split into two separate single strands. Translation is the process of joining each single DNA strand with a single strand of matching RNA.
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. Translation is the process of creating an amino acid chain using the encoded messenger RNA.
Answer:
1
Explanation:
In transcription, the genetic code of a DNA molecule is transferred to a messenger RNA molecule. The translation is the process of creating an amino acid chain by using the encoded messenger RNA. So the correct option is D.
What are transcription and translation?The first step in the process of gene expression is called transcription. In this process, the DNA sequence of a gene is copied for the formation of an RNA molecule.
RNA polymerase enzymes link the nucleotides of DNA to form an RNA strand. The DNA strand is the template. For every gene in the genome, transcription is separately controlled.
The translation is the process by which an mRNA molecule encodes for a protein. The process of translation happens with the help of tRNA in the ribosomes.
Translation requires ATP which is produced by the tRNA. The tRNA in the ribosomes supplies energy to RNA for the transcription of proteins The entry of mRNA occurs by the smaller subunit of RNA and the amino acid chain extends from the larger subunit.
Therefore the correct option is D.
