What type of molecule dose genes they code for?
Genes code for proteins
How are genes and proteins related?
one gene codes for one protein - apex
What do proteins have to do with genes?
Genes are sections of DNA which contain the code to make different proteins. DNA is made of long chains of 4 different chemical bases, A,C,G and T. The combination of these bases provides the information on the sequence of amino acids that make a particular protein.
An expressed gene is one that?
is transcribed into RNA. Promoters (I think that's what you meant, right?) don't function as genes; they stand as a signal for RNA polymerase to begin transcription of the actual gene, which begins about 25 base pairs downstream of the promoter region in eukaryotic DNA. Expressed genes DO code for proteins, but not all protein-coding genes are expressed. For example, the cells in your heart contain genes that code for proteins needed only in your liver. While those genes definitely code for proteins, they're not expressed. Expressed genes (and non-expressed genes, Ke$ha Looks like a man, for that matter) are made of DNA, not mRNA.
Why can Bacteria are able to produce human proteins?
They reproduce quickly, so they often produce much of the desired protein in a short time.
Cells must regulate gene expression so that genes will only be expressed when the proteins are needed?
The answer is encoded in your question.
What part of a DNA molecule contains the instruction of making chromosome packaging proteins?
In prokaryotes the genes directly specify proteins.In eukaryotes the exons within the genes specify proteins, the introns within the genes are noncoding DNA that alternate with exons and are spliced out in the process of transcription to messenger RNA.
Do prokaryotes have genes?
Yes, prokaryotes have genes. Genes are segments of DNA that contain the instructions for making a protein or RNA molecule. Prokaryotes have a circular chromosome that contains genes, along with additional genetic material in plasmids.
Does prokaryotes have genes?
Of course they have genes. They need genes for survival and reproduction.
What materials does the genetic code produce?
What most people think about as genes produce proteins. Scientists now know that some of the genetic code produces segments of RNA that regulate the protein-producing genes.
What do genes contain instructions for?
Genes contain instructions for building proteins.
What type of molecule dose genes they code for?
Genes code for proteins
How do our genes control our proteins?
Genes contain our DNA. Proteins are synthesized according to data on DNA
Does proteins determine Genes?
No they are not. Proteins are synthesized as per the information present in the DNA or genes. So Genes are something which determine the phenotype or a character of an organism by making RNA and proteins.
What are some examples of proteins produced by genes?
If you're synthesizing the proteins yourself (meaning you didn't ingest them), then all proteins are produced by genes.
What kind of factors are caused by genes?
Genes produce proteins and what we are is determined by genes.
Is operon proteins?
Operon is not a protein. It is a segment of DNA that has cluster of genes controlled by the elements such as promoter, operator. Lac operon is a classic example where it regulate the utilization of Lactose in the medium.
