Answer:

A stop Codon is the last sequence of base pairs (A,T,C,G) that tells when a new protein and amino acid are formed.

Answer:

In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into protein

Explanation:

Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.

Segments of DNA that contain the code for specific proteins are called _____.

VLD [36.1K]

These segments of DNA that contain the code for specific proteins are called genes.

Actual coding region of DNA are called exons.

Explanation:

A segment of DNA that codes for one distinct protein is called a gene. Each chromosome carries thousands of various genes. The genetic code of the DNA ever prevails protected inside the nucleus.

a gene is a stretch of DNA. Nucleotide consists of a sugar, phosphate and a base.. Genes are organized and packaged in units named “chromosomes.” Humans have 23 pairs of chromosomes.
