heterozygous means it is not the same gene expression

Answer:
The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds
Explanation:
The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.
Answer:
Actually, they have all of these features
Explanation:
Sister chromatids are replicated chromosomes formed during DNA replication at the Interphase stage. Since one is a replica of the other, they are the same in lenght, alleles content and every other aspect. They are joined together at the centromere.
Sister chromatids are separated from each other into each daughter cell at the Anaphase II of meiosis II and Anaphase of mitosis specifically. Hence, they remain attached to one another by their centromere until they reach Anaphase. Every chromosome contains the telomere at their end region and it plays a vital role in ensuring that neighboring chromosomes do not join.
Answer:
The correct answer would be d chloroplasts, which can be found in leaf cells of trees.
Chloroplasts are double-membrane cell organelle usually present in leaf cells of a plant.
They are the site of photosynthesis in plants by which plants convert solar energy into sugars. Oxygen is released as the byproduct of the process.
Light reaction of the photosynthesis takes place in the thylakoid membrane. It produces ATP and NADPH and releases oxygen.
Dark reaction takes place in the stroma of the chloroplast in which ATP and NADPH are used to fix carbon (obtained from carbon dioxide) into sugars (glucose).
The overall reaction is:
6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂
