The Nucleus is the cell structure that contains chromosomes which hold the genetic information of the individual.
What do you mean by DNA?DNA stands for Deoxyribonucleic acid. It is one of the most common types of genetic material in most organisms. It is found in both forms single-stranded or double-stranded.
Chromosomes are made up of tightly coiled DNA and consist of proteins known as histone proteins and provide all the master instructions to the cells.
Therefore, the chromosome inside the nucleus is the cell structure made of DNA that gives all of the master instructions for the cell.

Germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).
What is a dominant trait?In genetics, dominance refers to the phenomenon where one allele completely masks the expression of another allele (the recessive allele) in heterozygous individuals.
In this case, the genetic cross might be Parental 1 (AA) x Parental 2 (Aa) >> Filial 1 F1 1/2 AA + 1/2 Aa.
In conclusion, germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).

A trait I which the alleles are not dominant over one another
Answer:
They are co-dominance and incomplete dominance.
Explanation:
Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.
Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.

in step 1 of protein synthesis describe two of the differences between the DNA template and its complementary RNA molecule
Answer:Proteins are synthesised (made) by the ribosomes using messenger RNA transcribed from DNA in the nucleus.
Explanation:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled. The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.
