How many DNA are there in a gene?
A gene is made up of one continuous strand of DNA, which contains the instructions for producing a specific protein. Each gene contains a unique sequence of nucleotides that encode the information needed for protein synthesis.
What protein does the eye color gene encode?
The eye color gene encodes for a protein called OCA2 (P gene), which helps determine the amount of melanin produced in the iris. Melanin is responsible for the color of the eyes, with more melanin resulting in darker eye color.
Which section of DNA that provides information for a protein is called a?
The section of DNA that provides information for a protein is called a gene. Genes contain the specific sequences of nucleotides that encode the amino acid sequences of proteins. When a gene is expressed, it undergoes transcription to produce messenger RNA (mRNA), which is then translated into a protein.
What is the difference between a cistron and a gene?
A cistron is a segment of DNA that encodes a single polypeptide chain, while a gene encompasses all the functional elements involved in the expression of a specific trait. In simpler terms, a cistron is a part of a gene that codes for a protein.
How many exons are in CFTR?
The CFTR (cystic fibrosis transmembrane conductance regulator) gene contains 27 exons. These exons encode the protein responsible for regulating chloride ions across epithelial cell membranes, and mutations in this gene are associated with cystic fibrosis.
What protein does the eye color gene encode?
The eye color gene encodes for a protein called OCA2, which plays a role in determining the color of the eyes.
Section of DNA within a gene that do not encode part of the protein that the gene produces are called?
Introns (the stuff between the exons), and UTR (Untranslated region, the stuff before the start codon, and after the stop codon).
What is the portion of the DNA molecule that contains the information for making 1 protein?
The portion of the DNA molecule that contains the information for making one protein is called a gene. Genes are specific sequences of DNA that encode instructions for creating a specific protein. The process of making a protein from a gene involves transcription of the gene into messenger RNA (mRNA) and translation of the mRNA into the corresponding protein by ribosomes.

A gene is made up of one continuous strand of DNA, which contains the instructions for producing a specific protein. Each gene contains a unique sequence of nucleotides that encode the information needed for protein synthesis.

The eye color gene encodes for a protein called OCA2 (P gene), which helps determine the amount of melanin produced in the iris. Melanin is responsible for the color of the eyes, with more melanin resulting in darker eye color.
What usually is a set of instructions for making a particular protein?
A set of instructions for making a particular protein is called a gene. Genes are made up of DNA sequences that encode the specific sequence of amino acids that make up a protein. These instructions are transcribed from DNA to mRNA and then translated into a protein by ribosomes.
What do genes encode?
Genes encode the instructions for building proteins, which are the primary functional molecules in cells. These proteins determine the structure and function of cells, tissues, and organs in an organism. Additionally, genes also regulate gene expression, cell processes, and overall development.
Which section of DNA that provides information for a protein is called a?
The section of DNA that provides information for a protein is called a gene. Genes contain the specific sequences of nucleotides that encode the amino acid sequences of proteins. When a gene is expressed, it undergoes transcription to produce messenger RNA (mRNA), which is then translated into a protein.
What are ncRNAs and how do they differ from RNAs that encode proteins?
Non-coding RNAs (ncRNAs) are a type of RNA molecule that do not encode proteins. They play various regulatory roles in the cell, such as controlling gene expression. In contrast, RNAs that encode proteins are called messenger RNAs (mRNAs) and carry the genetic information needed to produce proteins. The main difference between ncRNAs and protein-coding RNAs is their function - ncRNAs regulate gene expression without producing proteins, while protein-coding RNAs are translated into proteins.
What is the difference between a cistron and a gene?
A cistron is a segment of DNA that encodes a single polypeptide chain, while a gene encompasses all the functional elements involved in the expression of a specific trait. In simpler terms, a cistron is a part of a gene that codes for a protein.

What is the place on a chromosome that gives information for a protein?
The place on a chromosome that provides information for a protein is called a gene. Genes are segments of DNA that encode the instructions for synthesizing proteins, which perform various functions within the cell. Each gene consists of a specific sequence of nucleotides that determines the amino acid sequence of the protein it codes for. The expression of genes is regulated and can be influenced by various factors, leading to diverse protein functions in an organism.
