DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
DNA codes for ____ which determine ____
A
mRNA, tRNA
B
mRNA, ribosomes
C
proteins. traits
D
proteins, peptide bonds
Explanation: 

Detailed explanation-1: -DNA is referred to as the genetic code, which carries information that controls a variety of traits in an individual. DNA encodes information that is used to make proteins, or functional molecules that regulate the physical traits of an individual. DNA is first translated, or copied, into a molecule of messenger RNA.

Detailed explanation-2: -The right answer to this question is that “The sequence of DNA that codes for a protein and thus determines a trait is called a gene".

Detailed explanation-3: -Gene. A segment of a DNA molecule (a sequence of bases) that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism.

Detailed explanation-4: -Genetic code refers to the instructions contained in a gene that tell a cell how to make a specific protein.

Detailed explanation-5: -A protein is made up of one or more long, folded chains of amino acids (each called a polypeptide), whose sequences are determined by the DNA sequence of the protein-encoding gene.
