I believe the correct answer is The nucleus stores the coded instructions for making the cell's proteins.

Explanation:

The nucleus is an enclosure of genetic material that is coded with information regarding the cell and it is these coded DNA molecules that are arranged and transcribed by the cell to make proteins in another organelle called the ribosome through the aid of tRNA.

Further Explanation:

False answers:

The nucleus is surrounded by a cell membrane that lets materials in and out of the cell: This is a false answer. The nucleus has a nucleus membrane but it does not allow just any material in and out of the cell but rather it has specific receptors which are just specified attachment sites for molecules that need to produce a response through stimulating for cleavage and protein synthesis in the ribosomes from the nucleus. An example is hormones producing responses in cells by attaching to cell membrane receptors which cause a cascade of reactions that will cause protein synthesis in the cell. Steroid hormones such as testosterone and estrogen do not have receptors on the surface of the cell but rather inside the cell itself (Cytoplasmic receptors) and that is why they produce a response faster compared to non-steroid hormones.The nucleus usually contains a nucleolus region which is where mitochondria assembly begins. This is incorrect. The nucleus can contain a nucleolus but there is no assembly of mitochondria in it. Assembly of mitochondria occurs outside the nucleus.The nucleus of protein assembly: This also is false. Protein assembly occurs in the ribosomes. In the nucleus, the DNA is unwound and transcription made. Later on, a complemantary DNA strand is made in the ribosome which is used to make chains of amino acids into proteins from the already made complementary DNA. Stop codons determine when to cut the amino acids to make different types of proteins.Learn More:

Approximately 90% of all cases of polycystic kidney disease are inherited in an autosomal dominant fashion. the disease is typically related to mutations to genes (pkd1 and pkd2). pkd genes can be found on chromosome 16. the disease occurs in approximately 1: 800 to 1: 1000 people. here is a hypothetical example. the dominant allele d will cause the development of pkd. the recessive allele is known as d. what genotypes would correspond to suffering from pkd? dd, dd what genotypes would correspond to being normal (not suffering from pkd)? dd consider that 1: 1,000 people have pkd in your population of 325million. consider that pkd is inherited in an autosomal dominant fashion. show you math for all of the following questions: what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is the genotypic frequency for dd? what is p? what is q? how many people in your population would have pkd?
