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.
Why mitochondria are able to make some of their proteins?
as they contain their own DNA and hence are able to synthesize proteins,but the DNA contains small number of genes so it is able to produce some of the proteins.
What type of genes are found in mitochondria?
It is highly suggested by observation that the few genes left to mitochondria to synthesize some proteins are prokaryote in nature as they are circular in the structure of the single chromosome.
Different between DNA and polypeptide?
DNA is divided into functional units called genes. A gene(def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis. The term polypeptide (def) refers to many amino acids (def) connected by peptide bonds (def). While all proteins are polypeptides, not all polypeptides are proteins. In some cases, smaller polypeptides coded for by two or more genes must be joined together to produce a functional protein. In other cases, as will be mentioned below, mRNA carries a transcript of several genes resulting in the synthesis of a large polypeptide that must subsequently be cleaved by enzymes called proteases into two or more smaller functional proteins. For simplicity, we will use the term proteinwhen referring to the end product of transcription and translation.-sudarvizhi prashanth
How many genes are there on a single genome?
One gene can code for multiple proteins.
True or False some genes code for enzymes?
the instructions for making some proteins are not specified by genes
A typical gene contains the instructions for making?
It depends. Some genes determine a single trait all by themselves. Some genes work with other genes to make a trait. It takes several separate genes to determine how tall you will be. And then there are other genes that by themselves determine multiple traits. Each gene is the code for a peptide chain. Many of those become proteins.
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 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.
Are the instructions for making some proteins not specified by genes?
The instructions for making some protiens ARE specified by genes.
How is it possible that there is twice as many proteins as there are genes and at the same time some genes do not code for protein?
About 1/3 of the coding genes have splicing variants . On average each gene has ~1.7 splicing varinats. My rough calculation is based a glance on NCBI gene database.
What are proteins made in cell?
The proteins that are made in the cell are the ones that the genes transcribe and thus translated into protein. Central dogma of biology is that a gene will transcribe mRNA which will then be translated into protein. Every cell has the entire human genetic code but will not produce all the possible protein. Genes are generally suppressed or inhibited. So some signal or some factor that will serve as an inhibitor of the suppressor of specific genes will cause a specific gene to be transcribed and thus specific proteins to be expressed. So in a cell whatever signals that induce transcription will make those specific proteins.
Why mitochondria are able to make some of their proteins?
as they contain their own DNA and hence are able to synthesize proteins,but the DNA contains small number of genes so it is able to produce some of the proteins.
Do cell membranes contain genes?
No, they do not. They do contain some proteins and fats called lipids. Genes are found in the cell nucleus in the form of DNA.
What type of genes are found in mitochondria?
It is highly suggested by observation that the few genes left to mitochondria to synthesize some proteins are prokaryote in nature as they are circular in the structure of the single chromosome.

What is a zinc finger?
A zinc finger is a structure within some proteins which binds to specific sequences of DNA and regulates genes.
