The first stage is called the transcription. During transcription, an RNA copy of gene is made.During translation, the second stage of gene expression,three different kinds of RNA work together to assemble amino acids into a protein molecule.
1. The first step is transcription (When DNA serves as a template for production of an RNA molecule) and the second step is translation (takes place in the cytoplasm, gene expression leads to protein synthesis in this step). This should help, got it right out of my college Biology book, good luck!
The two main steps in gene expression are transcription and translation. In eukaryote cells transcription occurs in the nucleus, and translation occurs in the cytoplasm.

A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
Alleles are the different types of genes.
1) There are certain aspects of gene expression that are different in eukaryotes and bacteria. The difference can be fixed with an expression vector, a cloning vector that contains a highly active bacterial promoter upstream of a restriction site where the eukaryotic gene can be inserted in the correct reading frame. The bacterial host cell will recognize the promoter and continue to express the foreign gene that is linked to that promoter. 2) Another problem is the presence of non-coding regions, introns, that are in most eukaryotic genes. The intorns make the gene very long and prevents the correct expression of the gene by bacterial cells. [Remember: bacteria does not have the RNA-splicing machinery] This problem is overcome by using a cDNA for of the gene, which includes exons.
It's false because the second Step is translation.
well, genotype can be the two alleles for any given gene, while phenotype is the actual (observable) expression of that gene.

Instead of having only two alleles for a trait, there are more than two. An example in humans is the ABO blood group system, where there are three alleles that are possible. However, an individual can only inherit the alleles of his/her parents, for a total of two alleles.

•A gene is a segment of DNA which codes for a specific protein. Through transcription and translation, a protein is produced and then is used for cell processes.

1. making it possible for a single gene to produce several different forms of RNA 2. It would make it possible for every small changes in DNA sequences to have dramatic effects in gene expression
