DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A string of nucleotides that contain the information to make a specific protein
A
Ribose
B
Amino Acids
C
tRNA
D
Gene
Explanation: 

Detailed explanation-1: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Detailed explanation-2: -DNA is a polymer consisting of strands of nucleotides. There are just 4 nucleotides in DNA and they only differ in one aspect, their nitrogenous bases: Adenine and Guanine, the Purines, and. Thymine and Cytosine, the Pyrimidines. DNA molecules are in a form known as a “double-stranded helix".

Detailed explanation-3: -A codon is a DNA or RNA sequence of three nucleotides (a trinucleotide) that forms a unit of genomic information encoding a particular amino acid or signaling the termination of protein synthesis (stop signals). There are 64 different codons: 61 specify amino acids and 3 are used as stop signals.

Detailed explanation-4: -Genes specify functional products (such as proteins) A DNA molecule isn’t just a long, boring string of nucleotides. Instead, it’s divided up into functional units called genes. Each gene provides instructions for a functional product, that is, a molecule needed to perform a job in the cell.

Detailed explanation-5: -A gene consists of a string of nucleotides. that give the cell information about how to make a specific trait.
