b. 28; replicated
c. 100, replicated
d. 25: unreplicated
e. 6.50; Replicated

50 visible chromosomes and replicated.

Explanation:

When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).

Interphase is composed of stages G1, S, and G2. During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.

Meiosis occurs after the interphase is over.

Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.

At the beginning of prophase 1, DNI is condensed in a well-defined chromosome formed by two sister chromatids joined by a centromere. Each chromosome carefully pairs with its homologous chromosome. Homologous chromosomes aline together to make the crossing-over possible, the stage where they interchange their parts.

The whole set of chromosomes is present in prophase 1. The reduction occurs later.

So if the germ cell has 50 chromosomes, the same 50 will be visible during prophase 1. DNA has already been replicated during the S stage of interphase.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
