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.

the difference is that proteins build humans and polypeptides build cells
The amino acid sequence of a polypeptide is determined by the sequence of its parent DNA. RNA is transcribed directly from DNA.
Exons
Cistron
No - they are different processes, although both use a DNA template. DNA transcription is the copying of DNA to create mRNA, which is then translated into a polypeptide (protein). DNA replication creates a new strand of DNA.
Recombinant- is the DNA fragment of interest Nonrecombinant- the undesired foreign DNA
The amino acid sequence of a polypeptide is determined by the sequence of its parent DNA. RNA is transcribed directly from DNA.

A specific stretch of DNA that programs the amino acid sequence of a polypeptide is called a gene.

Meat is a polypeptide. Any string or group of 50 amino acids is a polypeptide this includes DNA or RNA as well as many enzymes.

A linear stretch of DNA that specifies the sequence of amino acids in a polypeptide is called a gene. The primary function of DNA ligase is to seal new short stretches of nucleotides into one continuous strand.

IntrAchain H-bonds stabalize bonds between the same polypeptide chain (alpha-helices). IntErchain- H-bonds stablized between different polypeptide chain. (beta- structures)
No - they are different processes, although both use a DNA template. DNA transcription is the copying of DNA to create mRNA, which is then translated into a polypeptide (protein). DNA replication creates a new strand of DNA.
