A molecule of DNA consists of 2 chains of nucleotides, coiled around each other to form the familiar double helix.

Each DNA nucleotide contains one of 4 bases: (A)denine, (G)uanine, (C)ytosine, (T)hymine. Each base is paired with it's complementary base on the opposite chain:

Adenine with Thymine (AT) and Guanine with Cytosine (GC).

Genetic words are a 3 base sequence that specifies a particular amino acid. There are 64 possible combinations of these 4 bases in the 3-base genetic words:

(4 x 4 x 4 x 4 = 64).

61 of these combinations are used to code the 20 amino acids.

The other 3 combinations are stop sequences, used in synthesis.

A change is the sequence of amino acids is?

A change in the sequence of amino acids in a protein can alter its structure and function, potentially leading to changes in biological activity or stability. This alteration can impact the protein's interactions with other molecules and may result in functional consequences that affect the cell or organism. Slight changes in amino acid sequence can sometimes lead to significant changes in protein structure and function.


How does the sequence of DNA affect the function of a protein?

The sequence of nucleotides in DNA molecule is equivalent and is closely related to an amino acid sequence in the protein molecule. If for any reason the sequence of DNA nucleotides changes it will be reflected in amino acid sequence in the protein. Moreover, the correct sequence of amino acid in the protein will form the correct three-dimensional structure, or tertiary structure, that will confer the biological activity to protein. If a wrong amino acid is translated from a mutated gene in the DNA could change the spatial structure of the protein and therefore modify or erase its biological function.


Most genetic disorders results from a mutation that changes the amino acid sequence in a?

Most genetic disorders result from a mutation that changes the amino acid sequence in a protein. This change can lead to altered protein function, which can affect normal cellular processes and result in disease.


Why are Myostatin mutations nonsynonymous?

Myostatin mutations are nonsynonymous because they result in a change in the DNA sequence that leads to the production of a different amino acid in the myostatin protein. This change in the protein's amino acid sequence can alter its function or structure, leading to physiological consequences such as increased muscle mass.


When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?

The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.

How is it possible for a point mutation to have no effect on the function of gene?

If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.

Why the addition of an extra base in a DNA sequence would change the message carried by a DNA molecule?

It could change the type of protein that would be produced hence change the structure and function of that protein.

Synthesis of a defective protein may result from an alteration in?

the DNA sequence coding for the protein, leading to a mutation. This mutation can cause a change in the amino acid sequence, affecting the protein's structure and function. Defective protein synthesis can also result from errors in the transcription or translation processes.


How can a mutation in DNA base sequence cause a change in a protein?

dna in a cell needs protein and chromosomes.


Explain why the addition of an extra base in a DNA sequence would change the message carried by a DNA molecule?

The addition of an extra base in a DNA sequence would cause a frameshift mutation, shifting the reading frame of the genetic code. This would alter the codons specifying amino acids in the protein sequence, leading to a different protein being produced.


What describes a substitution mutation and how does it impact the genetic code?

A substitution mutation is a type of genetic mutation where one nucleotide is replaced by another in the DNA sequence. This can lead to a change in the amino acid sequence during protein synthesis, which can alter the function of the protein produced. The impact of a substitution mutation on the genetic code depends on where it occurs in the DNA sequence and what amino acid is substituted, which can result in a variety of effects ranging from no change to a significant alteration in the protein's function.
