What would happen if you forget to add rnase solution in dna extraction?

There can be several reasons for differences in enzyme activity, including temperature, pH, enzyme concentration, substrate concentration, and the presence of inhibitors or activators.

Enzymes are biological catalysts that accelerate chemical reactions in the body. The rate of enzyme activity can be affected by various factors, such as temperature and pH. Each enzyme has an optimal temperature and pH range at which it functions best. Deviations from this range can cause the enzyme to denature or lose its shape, leading to a decrease in activity.

Changes in enzyme concentration can also affect activity. An increase in enzyme concentration generally leads to an increase in activity, while a decrease in concentration leads to a decrease in activity. The rate of enzyme activity can also be affected by substrate concentration.

Answer:

The major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation. DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

That’s what RNA has that DNA doesn’t.

Humans have two sets of homologous chromosomes, so humans are usually diploids, but some organisms can have three or more sets of homologous chromosomes, and that is what we call polyploidy.

Polyploid commonly happens due to abnormal cell division, where the chromosomes fail to separate, or it can be caused by chemical substances.

Polyploid is very common in plants, while most animals are diploids and produce haploid gametes. This is because plants have a different life cycle, and also because self-fertilization commonly happens.

In plants, polyploid is responsible for a good percentage of the speciation events, where the new species has a higher ploidy than the original ones. The fact that there are more copies of certain genes can give adaptive advantages, which promotes rapid speciation.

Most of the polyploid species are the result of sexual reproduction, with an even number of chromosomes, however, there are some triploid species that can only reproduce asexually.

This means C, it can happen fast would be the right option.

The process of Glycolysis is a catabolic process  in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .

Mechanism Of Glycolysis

The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol

Preparatory phase refers to the  generation of two molecules of  glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .

Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate  .

Both the phases of glycolysis takes place in the cytoplasm and there are  three enzymes that involved in regulating the glycolytic pathway .This process is also known as the catabolic process .

Answer:yes

Explanation:

The best interpretation of these results Is that, key element of plant gene control is through chromatin regulation.

All eukaryotes include chromatin that is crammed into nucleosomes; the majority of the chromatin protein component is made up of members of the histone family of proteins. Since histone proteins have a positive charge, they can get close to Deoxyribonucleic acid.

Core histones include three and four molecules of hydrogen, which are found on the inner of the nucleosome and bind to Deoxyribonucleic acid before other histones. The chromatin architecture blocks transcription factors, polymerases, and other nuclear proteins from accessing Deoxyribonucleic acid when it is substantially condensed.

The statement (D) is correct. Multiple rod-like chromosomes.

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.

Moreover, chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Hence, chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division. This ensures that our inner workings proceed smoothly and efficiently.

Explanation:

Bottled water is often more expensive, produces transportation pollution, and contributes to plastic waste. In contrast, tap water costs less, doesn't generate transportation pollution, and doesn't produce plastic waste. Tap water is also typically held to more stringent quality standards than bottled water.

To correctly categorize each phrase as describing bottled water or tap water, let's analyze the given options:

1. Costs less: This phrase generally describes tap water. Tap water is often more cost-effective compared to bottled water, as it is supplied through municipal water systems and is readily available in households. Bottled water typically incurs additional costs associated with production, packaging, and transportation.

2. Produces transportation pollution: This phrase primarily applies to bottled water. The production and distribution of bottled water involve transportation, which contributes to carbon emissions and pollution. Tap water, on the other hand, doesn't typically generate transportation pollution since it is supplied through local water infrastructure.

3. Produces plastic waste: This phrase specifically pertains to bottled water. Bottled water is packaged in plastic containers, contributing to plastic waste and environmental concerns. Tap water, however, doesn't produce plastic waste as it is consumed directly from the tap without additional packaging.

4. Held to more stringent quality standards: This phrase generally describes tap water. Tap water is regulated by governmental agencies and must adhere to strict quality standards, including regular testing and monitoring. Bottled water is also subject to quality regulations, but the oversight and standards applied to tap water are often more extensive.

Essential amino acids must be obtained from the foods we eat.

All essential amino acids must be obtained from the foods we eat. Thus, the correct option is A.

An essential amino acid is also known as indispensable amino acid, these are the amino acids which cannot be synthesized from scratch by the organism fast enough to supply its demand in the body, and it must therefore come from the diet an individual eats. Of the 21 amino acids which are common to all life forms, the nine amino acids that humans cannot synthesize include valine, isoleucine, leucine, methionine, phenylalanine, tryptophan, threonine, histidine, and lysine.

Six other amino acids that are considered as conditionally essential in the human diet, meaning that their synthesis can be limited under special pathophysiological circumstances, such as prematurity in the infant or individuals in the severe catabolic distress. These six amino acids are arginine, cysteine, glycine, glutamine, proline, and tyrosine.
