size hence streams are little and rivers are bigger than streams because a stream connects between two or more rivers
mark brainliest please :)
Answer:
1 - C
<em>Protein</em> - This folded amino acid chain is genetically encoded and performs specific functions in the cell.
2 - A
<em>DNA</em> - This series of nucleotides encodes proteins.
3 - D
<em>Chromatin</em> - This substance is made up of fibers that are formed in the nucleus by supercoiling genetic material.
4 - B
<em>Histones</em> - These proteins regulate transcription and modifications of genetic material.
Explanation:
1. Proteins are <u>molecules composed of one or more chains of amino acids</u>. They perform fundamental functions in all living beings. For example, they are the main components of muscle, or act as enzymes.
2. DNA, or deoxyribonucleic acid, carries the genetic information and instructions to produce proteins in all living beings. <u>DNA will be converted to messenger RNA (mRNA) by enzymes, which will be translated into a protein.</u>
3. Chromatin, located in the nucleus, is composed of genetic material and proteins that condense to form chromosomes. Moreover, it <u>is made up of fibers that are coiled and condensed to form chromosomes.</u>
4. Histones are proteins that pack the genetic material, or DNA, into units called nucleosomes. <u>They are involved in the transcription and modification of DNA.</u>
The mutation occurs in the red bacterial cell in generation 2.
An alteration in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA is referred to as a mutation. DNA or RNA can be found in the viral genome.
Environmental elements known as mutagens are what trigger mutations. Radiation, chemicals, and pathogenic agents are examples of mutagens. Mutations may occur naturally spontaneously.
Red blood cells are impacted by thalassemia, a genetic blood condition. A change in the cell that produces hemoglobin is the cause of thalassemia. Anemia is brought on by the mutation's disruption of hemoglobin formation, which results in low hemoglobin levels and a rapid loss of red blood cells.
