Why can a change in the amino acid sequence of a protein be damaging to its function?
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.
What are 4 phicical changes?
A physical change is a substance that changes, and has the ability to change back into the same substance it was before. So signs of a physical change is: a) phase change b) shape change etc.....
How do mutations affect proteins?
. by changing the number of mRNA bases that make up the codons 2. by preventing the ribosome from binding to the mRNA 3. by changing the sequence in amino acids brought to the ribosome 4. by creating codons with no complimentary anti-codons
Where is the protein found in a cell?
Protein is found in virtually every part of a eukaryotic cell. Here are a few examples: Nucleus: DNA is bound by histones, a 4 subunit protein. Nuclear pores are also proteins. Endoplasmic Reticulum: Ribosomes are proteins. Cytoplasm: The cytoskeleton that holds the shape of cells is made of protein filaments. Mitochondria: ATPase and all of the cytochromes are proteins. Plasma Membrane: Surface proteins help the body identify the kinds of cells.
What are the characteristic of physical change?
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.
What are 4 factors that can destroy the shape of a protein?
temperature,ph,

Can force change the shape of an object?
The 4 main forces that can change the shape of an object are stretching, compressing, bending and twisting.
How does ATP enable transport proteins to move ions across a cell membrane?
Once translated, proteins are dispersed throughout the cellular environment. This section covers the transport of a protein into a specific organelle--the mitochondria.
Which forces can change the shape of an object?
The 4 main forces that can change the shape of an object are stretching, compressing, bending and twisting.
What 4 factors determine a chemical change?
heating is one of them
What are the Factors that can cause a change in supply?
In most models, the factors that can cause a change in supply include: 1) Change in the capital stock. 2) Change in the labour stock. 3) Change in the level of technology. 4) Change is utilisation rates of capital and labour.
Is antibody a Y-shape protein?
It is a T or Y-shaped monomer of 4 looping linked polypeptide chains
