In each somatic cell there are 46 DNA molecules,

For the second question how protein synthesis occur, it occurs by transcription and translation. Transcription occurs in the nucleus and translation occurs in the cytoplasm.
I would suggest you to visit a website, for more detail.
I put the link below,

I hope this helps

How many chromosomes are in a sperm cell from an animal whose somatic cells have 32 chromosomes (2n=32)? If 2n=32, how many chromosomes are in a haploid cell?

So in an animal with 32 (2n) chromosomes in somatic cell, number of chromosomes in sperm will be 16 (n).

Is it true that your somatic cells have chromosomes just like the ones in your dad's sperm and your mom's egg, but that those chromosomes are not so similar to the chromosomes that your dad had in his somatic cells? How can this be explained?

Somatic cells will be in diploid condition and Germ Cells will be in Haploid condition. So, Somatic cells cannot have chromosomes like those in the sperm or egg cell.

Is a kidney cell an example of a sex cell, a germ cell, a somatic cell or a haploid cell?

Kidney is not a reproductive organ, hence there is no germ cell or haploid cell in kidney. Cells in kidney are all diploid.

Which RNA molecules are involved in the synthesis (making) of a protein?

The gene (DNA) gets turned into a copy of pre-messener RNA (pre-mRNA). This pre-mRNA get spliced by the splicesome (which contains its own RNA, but this is rarely considered part...

Where does transcription occur and where does translation occur in the cell?

Terms transcription and translation in biology are generally related to the DNA and its properties. Human cells replicate. In order to do that, they have to produce the same constituents...

What steps occur during protein synthesis?

Transcription is the process where mRNA is made. After mRNA is created, it goes out of the nucleus and attached itself to a ribosome, and translation begins. During translation, the...

Describe the cell membrane, cell wall, nucleus, and cytoplasm. Which of these structures are you likely to find in a prokaryotic cell, Eukaryotic cell, plant cell or animal cell?

Basic Definitions: = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere. Cell Wall = the rigid 'armor' of the...

Which kind of cell can divide by mitosis, a germ cell or a somatic cell? What kind can undergo meiosis?

Mitosis is for growth and repair. One cell becomes two daughter cells with each containing 46 chromosomes and retains the exact feature of that cell. Meiosis is for reproductive cells....

If there are 32 sister chromatids in a normal somatic cell, what is the haploid number for that cell?

The sister chromatds are found in same chromosomes. Each chromosome has two sister chromatids joined at the centromere. The nuber of chromatids are double than the number of chromosomes. Thank...
