Functionality of Genes and chromosomes is described below.
Explanation:
- Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.
- Genes are contained in chromosomes, which are in the cell nucleus.
- A chromosome contains hundreds to thousands of genes.Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
- A trait is any gene-determined characteristic and is often determined by more than one gene.Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
- The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
- the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
- The phenotype is the actual structure and function of a person’s body. The phenotype is how the genotype manifests in a person—not all the instructions in the genotype may be carried out (or expressed). Whether and how a gene is expressed is determined not only by the genotype but also by the environment (including illnesses and diet) and other factors, some of which are unknown.
- A karyotype is a picture of the full set of chromosomes in a person’s cells.
Answer:
As one plate moves into subduction zone, magma is formed and moves upward. As magma rises, it picks up rocks, minerals, and sediments from overlaying plate. Most volcanoes on land are because of oceanic-continental subduction. Characterized by explosive eruptions
Explanation:
Answer: C
Explanation:
Pyruvate dehydrogenase complex (PDH) is covalently modified by phosphorylation by PDH kinase and dephosphorylation by PDH phosphatase.
The dephosphorylated form of the enzyme is active. Hence activators of PDH kinase like ATP, NADH and acetyl CoA inhibits the PDH reaction
PDH phosphatase is activated by Ca++, Mg++ and AMP; this will increase the rate of PDH reaction where as PDH kinase is inhibited by Ca++. When there is adequate ATP and acetyl CoA the enzyme is inhibited.
the answer is D Nucleus, which has genes that contain many chromosomes
