Answer:
A peptide bond is a covalent bond formed between two amino acids. Living organisms use peptide bonds to form long chains of amino acids, known as proteins. Proteins are used in many roles including structural support, catalyzing important reactions, and recognizing molecules in the environment. A peptide bond is therefore the basis of most biological reactions. Forming peptide bonds is a requirement for all life, and the process is very similar in all forms of life.
Explanation:
Answer:
1. chromosome: tight coils of DNA
2. Eukaryote: a cell that has a membrane-bound nucleus
3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits
4. Prokaryote: a cell whose nucleus is not bound by a membrane
5. Trait: genetic characteristic of an individual
Explanation:
Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.
A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.
The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.
A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.
The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
I think the answer is two
Answer:
The thrust of the air propels the balloon in the opposite direction
Explanation:
Answer:
A. Multiple allele because a trait is controlled by three different genes
Explanation:
Multiple allele because a trait is controlled by three different genes
polygenic because the offspring have alleles from both parents
multiple allele because the offspring have alleles from both parents
polygenic because a trait is controlled by three different genes
