How is it possible to have different genes and make the same proteins?

Scientists have long known that it’s possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA.

How is it possible for a single gene to code for two different proteins in eukaryotes?

Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by the differential inclusion or exclusion of regions of pre-mRNA. Gene splicing is an important source of protein diversity.

What is translation and how does it relate to gene expression?

​Translation Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes.

How do different genes in your DNA code for different proteins?

Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) Through the processes of transcription and translation, information from genes is used to make proteins.

Is it possible to find the same gene in two different kinds of organisms but not find the protein that is produced from that gene?

Is it possible to find the same gene in two different kinds of organisms but not find the protein that is produced from that gene? Yes, this phenomenon is made possible by latent genes, or genes in an unexpressed state.

Do different cells have different genes?

Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. The set of genes expressed in a cell determines the set of proteins and functional RNAs it contains, giving it its unique properties.

How many different reading frames are possible for mRNA?

three possible reading frames
The mRNA is single-stranded and therefore only contains three possible reading frames, of which only one is translated. The codons of the mRNA reading frame are translated in the 5′→3′ direction into amino acids by a ribosome to produce a polypeptide chain.

What is the difference between gene expression and gene product?

Gene expression refers to the process by which the instructions in our DNA are converted into a functional product, such as a protein, while gene regulation refers to the process involved in turning genes on and off to ensure the appropriate expression of genes at the proper times.

Would you expect to find the same gene in two different kinds of organisms if so which ones?

Two different organisms can have the same gene, but organism 1 may have it in a latent state while the other may have the same gene as organism 1, but in an active and expressed state, therefore creating the protein associated with the shared gene.

How similar is the gene sequence for each gene?

The gene sequence similarity percentage is 100\%.

How many reading frames are used to translate a gene?

Typically only one reading frame is used in translating a gene (in eukaryotes), and this is often the longest open reading frame. Once the open reading frame is known the DNA sequence can be translated into its corresponding amino acid sequence. An open reading frame starts with an atg (Met)…

What is the relationship between open reading frame length and protein coding?

The longer an open reading frame is, the longer you get before you get to a stop codon, the more likely it is to be part of a gene which is coding for a protein.

Which genes are involved in lipid and glucose metabolism after go?

Among them, IGFBP7, Notch1 and HMGCR were up-regulated (2.85-fold, 3.22-fold, and 2.06-fold, respectively, all P < 0.05) and ACACB was down-regulated (2.08-fold, P < 0.01). These four genes supposed to connect lipid and glucose metabolism after GO and Pathway analyses.

What is an open reading frame in DNA?

The genetic code reads DNA sequences in groups of three base pairs, which means that a double-stranded DNA molecule can read in any of six possible reading frames–three in the forward direction and three in the reverse. A long open reading frame is likely part of a gene. “Open reading frame” is a terrible term that we’re stuck with.
