Do we have 30000 genes?
The human genome is actually not that much more complex than a modern jet aeroplane, which has more than 200,000 unique pieces, each of which interacts with three or four others on average. This is despite the fact that the human genome only has 30,000 genes in human DNA.
With the intention of understanding the bulk of the human genome, the Human Genome Project (HGP) was started. This involved identifying every human gene and mapping it out along the genome, as well as learning how much coding DNA we had and learning about human physiology, evolution, and development. The ultimate goal was to boost biomedical research by decoding crucial knowledge about how the entire genetic material functions.

What are three facts about chromosomes?
Each chromosome is made up of a lengthy DNA thread that connects hundreds of genes. The 46 chromosomes found in cells are divided into 23 pairs. Your mother and father each contribute one chromosome to each pair that you have.
Our genes are the chemical codes that govern every aspect of your body's function, composition, and appearance. Over 20,000 distinct genes chromosomes exist in humans. Every gene in your body is duplicated in every cell.
Your body's smallest building blocks are called cells. Your organs are made up of several cell kinds. Your brain has neuron cells, your liver contains liver cells, and your stomach contains cells that produce stomach acid. Genes regulate the development and function of every cell.
One gene alone is responsible for some bodily functions. But many genes work together to control the majority of things, like your height and weight.

What does fragmented mean?
Answer:
it means to be broken into small peices like when glass gets shatterd
Explanation:
Imagine you are a genetic counselor and a couple (Martin and Shelley) comes to you for information. Martin has a sibling with sickle cell anemia, but neither he nor his parents have the disease. Shelley was married once before and did have a male child with sickle cell anemia. She does not have the disease herself. (sickle cell anemia is an autosomal, recessive disease)
What is the probability that their unborn baby will have sickle cell anemia?
The probability that their unborn baby will have sickle cell anemia is 1/4 or 25%.
Genetic probabilitySickle cell is an autosomal recessive disease. This means that both males and females have an equal chance of having the disease. They can also be carriers or not affected equally.
Martin does not have the disease but has a sibling with sickle cell anemia. It means his parents are each a carrier of the disease. Assuming the allele for sickle cell is s.
Ss x Ss
SS Ss Ss ss
Probability of unaffected = 1/4
Probability of being a carrier = 1/2
Probability of being affected = 1/4
Shelley was once married and had a male child with sickle cell. Since she does not have the disease herself, it means she's a carrier (Ss).
Assuming Martin is unaffected:
SS x Ss
SS Ss SS Ss
Probability of their unborn having sickle cell = 0
Assuming Martin is a carrier:
Ss x Ss
SS Ss Ss ss
The probability of their unborn having sickle cell = 1/4
Thus, the probability that their unborn baby will have sickle cell anemia is either 0 or 25%
P(A or B) = P(A) + P(B) - P(A and B)

what is the definition of epistasis 1 point
The state known as "epistasis" occurs when the expression of one or more additional genes alters (e.g., masks, inhibits, or suppresses) the expression of a specific gene.
Epistasis refers to the interaction of genes that influences a phenotype. One phenotype with different properties can be determined by a conditional relationship between two genes. Genes can either work together to form a new trait or can hide one another so that only one is identified as "dominant." When it comes to gene pathways, this is typically seen since the presence or absence of one gene product directly impacts the expression of another gene within the pathway. This is also known as allelic complementation or interallelic complementation.

Cellular differentiation enables multicellular organisms to develop cell types and body plans that are uniquely functional.
Cellular differentiation, or simply cell differentiation, is the process by which a cell's gene expression changes to become a more specific type of cell.
Cellular differentiation is the process by which cells become specialized, and it is critical to an organism's development because it allows them to create structures that perform the jobs required for survival. Differentiation occurs by turning certain genes on and others off, resulting in the formation of specialized cells for specific functions.

compare and summarize the three stages of cellular respiration
Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.
The cytoplasmic mechanism known as glycolysis converts glucose into two molecules with a total of three carbons and energy. Two molecules each of ATP, NADH, and pyruvate are generated during glycolysis: As glucose is broken down aerobically through catabolism, ATP, NADH, and pyruvate are produced as energy. Pyruvate then enters the citric acid cycle to create additional energy. Plants manufacture oxygen and sugar-based energy through a process known as photosynthesis, which uses sunlight, water, and carbon dioxide. When sunshine and water are present, plants use a process called photosynthesis to make food. Absorption of light, electron transfer, ATP production, and carbon fixation are the several stages of photosynthesis.

Based on the sucrose uptake model, experimental treatments that increase the rate of sucrose transport into cells is decreasing extracellular pH.
Is sucrose used in transportation? Sucrose is synthesized in the cytoplasm, translocated from cell to cell across the plasmodesmata or membranes, and either compartmentalized or transported to the apoplasm for uptake by neighboring cells. Sucrose, a relatively large polar compound, requires proteins to facilitate efficient membrane trafficking.Sucrose reaches the sieve tube via plasmodesmata and allows cell-to-cell diffusion in species such as gourd. It is converted into larger molecules (RFOs) by the sequential addition of galactosyl residues in modified companion cells (CCs) called intermediate cells.In plants, sucrose is the major transport form of photoassimilated carbon, the source of the carbon skeleton, and the energy source for non-photosynthetic plant organs (sink organs). As a molecule to be transported over distance, sucrose must pass through a series of membranes.Can cells take up sucrose?Dietary carbohydrates of particular importance include starches and disaccharides such as lactose and sucrose.
