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.

Can two dominant genes equal a recessive gene?

it could but then u would be deformed but usually it cant


What are two forms that a gene or allele may take?

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


Is todd homozygous or heterozygous for pku?

If Todd has PKU, he would be homozygous for the gene associated with PKU, meaning he has two copies of the faulty gene. This would result in the expression of the PKU disorder.


Different forms of gene?

Genes can exist in different forms called alleles, which are variations of a gene. Alleles can be dominant or recessive, influencing the expression of traits in an organism. Additionally, genes can undergo mutations, such as insertions, deletions, or substitutions, leading to genetic diversity within a population.


What are two problems with bacterial gene expression systems?

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.

What is multiple allele gene expression?

Multiple allele gene expression refers to a situation where a single gene has more than two alleles, or different versions of the gene, which can be expressed differently within an individual's genotype. This can lead to a wider range of possible phenotypic outcomes because each allele may contribute to the expression of a specific trait.

How many alleles is a gene controlled by?

A gene is controlled by two alleles, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), influencing the expression of the gene and determining an individual's specific traits.

What controls gene expression?

Gene expression is controlled by various mechanisms such as transcription factors, epigenetic modifications (DNA methylation, histone modifications), non-coding RNAs, and post-transcriptional modifications. These mechanisms influence whether a gene is turned on (expressed) or off (silenced) in a cell. Additionally, environmental factors and signaling pathways can also affect gene expression.

Does a polyploid plant have more than two copies of each gene?

Yes, polyploid plants have more than two sets of chromosomes, which means they can have multiple copies of each gene. This can lead to increased genetic diversity, altered gene expression, and potential advantages such as increased tolerance to stress or disease.

What the function of a homozygous?

A homozygous individual carries two identical alleles for a specific gene. This often leads to a consistent expression of the trait controlled by that gene. Homozygosity can have different impacts depending on whether the alleles are dominant or recessive.
