How is information for a specific protein carried on the DNA molecule?
A. As a sequence of nucleotides
B. In the double helix shape of the condensed chromosome
C.In the ratio of adenines to thymines
D.As a pattern of phosphates and sugars
A C D are all statements that make sense, but how do I know which one is correct for the situation
but I think it is A. can anyone explain
hi bestie ! did you ever figure it out? 😀
yup A. is the correct answer
Yes it is A ~ As a sequence of Nucleotides
Oh, you're looking for some scientific humor? Well, I can whip up a joke related to your question!
Why did the DNA go to the comedy club?
Because it had some really good nucleotides!
But let's get back to your question. You're on the right track with option A. Information for a specific protein is carried on the DNA molecule in the form of a sequence of nucleotides. Each protein has a unique sequence of nucleotides that acts as a blueprint for its production. So, I guess you could say that DNA is like the hilarious script for a protein comedy show!
To determine the correct answer among the options provided, we need to understand how information is encoded on the DNA molecule.
Option A states that information for a specific protein is carried on the DNA molecule as a sequence of nucleotides. This is the correct answer.
DNA is composed of a chain of nucleotides, each containing a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). The sequence of these bases forms the genetic code or instructions for building proteins.
The human genome consists of approximately 3 billion base pairs in a specific order. This order of bases carries the genetic information needed to create and regulate all the proteins in an organism. The sequence of nucleotides determines the sequence of amino acids in a protein, which ultimately determines the protein's structure and function.
Option B, referring to the double helix shape of the condensed chromosome, is incorrect because while the DNA molecule does adopt a double helix structure, it doesn't directly encode information about specific proteins in its shape.
Option C, relating to the ratio of adenines to thymines (A:T), is incorrect because although the DNA molecule has a complementary pairing between adenine and thymine, the ratio of A:T varies among individuals and does not directly encode specific protein information.
Option D, mentioning a pattern of phosphates and sugars, is also incorrect because while DNA is composed of phosphates and sugars, these components do not carry the specific information for proteins.
Therefore, option A is the correct answer, as the information for a specific protein is carried on the DNA molecule as a sequence of nucleotides.
