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 is the serving size for protein?
The recommended serving size for protein varies depending on factors such as age, gender, and activity level. In general, a serving size of protein is around 3-4 ounces for meat, poultry, or fish, or about 1 cup for plant-based sources like beans or tofu. It is important to consult with a healthcare provider or registered dietitian to determine the appropriate serving size of protein for your individual needs.
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.
What are 4 factors to change an electromagnet?

How does ATP enable transport proteins to move ions across a cell membrane?
ATP provides the energy needed for transport proteins to actively move ions against their concentration gradient across the cell membrane. This process involves a conformational change in the transport protein that allows it to bind to the ion on one side of the membrane, undergo a change in shape powered by the hydrolysis of ATP, and then release the ion on the other side of the membrane.
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
5 Clues to show physical change?
Change in state of matter (solid to liquid or gas). Change in shape or size. Change in color. Formation of bubbles or fizzing. Formation of a precipitate.
What are the 3 general factors of food?
all food is made up of some combination of fat, protein, and carbohydrate. fat has 9 calories per gram, protein and carbohydrate have 4 calories per gram
Describe 6 steps to the sodium potassium pump?
Three sodium ions bind to the pump protein inside the cell. ATP is split into ADP and phosphate, providing energy for the pump to change shape. The shape change allows the sodium ions to be expelled outside the cell. Two potassium ions from outside the cell bind to the pump. Another shape change releases the phosphate group, leading to the release of the potassium ions inside the cell. The pump returns to its original shape, ready to repeat the process.
4 grams of protein equals to how many kcal?
1 gram protein = 4 calories 4 gram protein = 4x4= 16 calories
