What are the effects of base-pair insertions and deletions?

Biology

Andrej [43]3 years ago

Answer:

DNA is divided into codons which are 3 bases long. Each codon codes for a specific amino acid or signals transcription to stop or start. Inserting or deleting one base pair changes how the DNA is read, so it will often alter the amino acids the DNA sequence produces. As a result, the protein made from the gene may not function properly.

Example:

AAT CGC CGA TGA

Delete the T from the first codon

AAC GCC GAT GA

The entire sequence is read differently ^

Explanation:

While, the following disorders and causes of the protein and nutrients deficiency can be described as follows:

Beriberi is rare in the United States.
Alcohol-related thiamin deficiency is called Wernicke-Korsakoff syndrome .
Most adults get adequate riboflavin in their diets.
Thiamin deficiency causes diarrhea, dermatitis, and dementia .

Drag and drop the terms at the left to match the appropriate descriptions at the right. ResetHelp Composed of phospholipid bilay

quester [9]

Answer: The appropriate description is matched against the components of the cell below.

1) Cilia: Short, hairlike cellular extensions

2) Ribosome: Site for protein synthesis

3) Chromatid: Copy of a chromosome

4) Cristae: Folds of the inner mitochondrial membrane

5) Lysosomes: Vesicles with powerful digestive enzymes.

6) Smooth ER: Stores calcium ions in muscle cells

7) Plasma membrane: Composed of phospholipid bilayer

8) Cytosol: Intracellular fluid

9) Cytoplasm: Intracellular fluid and organelles

10) Centriole: Involved in mitosis.

Explanation:

A cell is simply defined as the structural and functional unit of an organism. It is made up of highly organized physical structures called intracellular organelles. These organelles includes:

• Ribosome

• Lysosomes

• Smooth Endoplasmic reticulum

• Plasma membrane

A type of cellular motion called ciliary movement, is a whip-like movement of CILIA on the surface of cells takes place in the respiratory airways of human.

The cytoplasm is filled with both intracellular fluid and organelles while the cytosol contains mainly dissolved proteins, electrolyte and glucose ( intracellular fluid).

I don't really understand just started high school

Ksenya-84 [330]

A forest fire would burn large trees, fertilizing the soil and makes room for smaller plants to grow, which provides more food for herbivores. The lack of trees also makes it easier for carnivores to hunt prey. Good luck in high school!
