Answer:
10 chromosomes/sister chromatids
Explanation:
Prophase is the first stage of cell division (mitosis). Prior to the cell entering the actual division stage, it undergoes a phase where it prepares its content and most importantly undergo the duplication of its genetic material (DNA). This DNA are found as chromosomes. It undergoes replication of its DNA in the S-phase of interphase stage.
Since Arabidopsis thaliana has 10 chromosomes, and each chromosome holds one DNA molecule, 10 molecules of DNA will be present in the mustard plant's genome. These 10 molecules of DNA will be replicated on another copy of chromosome which is identical to the template. This chromosomes are called SISTER chromatids i.e. replicated chromosome. Each sister chromatids are held together at the centromere and are considered one individual chromosome until they separate during anaphase stage.
Hence, at the Prophase stage, before separation, each sister chromatid (replicated chromosome) is considered as one chromosome. Thus, in the mustard plant with 10 chromosomes, it will possess 10 sister chromatids or chromosomes at the Prophase stage.
N.B: When sister chromatids separate during anaphase stage, they will be regarded as individual chromosomes.
Antibodies
They can cause reactions which lead to inflammation, but they don't directly trigger inflammation.
Answer:
DNA polymerases
Explanation:
The formation of a phosphodiester bond between adjacent nucleotides is catalyzed by the DNA polymerases. They do this efficiently only if the incoming base on the incoming nucleoside triphosphate is complementary to the base on the template strand and can bind efficiently.
Answer:
Specialized cells because they preform a specific function
I wanna say it’s b but if not I’m so sorry !
