During the process of chromosome replication, A genetic error occurs. As a result, a sequence of events occurs as described belo

w. Event A. Protein with the new sequence of amino acids is produced. Event B: a DNA strand with an altered base sequence is formed. Event C:, A new inheritable trait is expressed in an organism. Event D, An mRNA strand with the new sequence of bases is synthesized. The usual order in which these events would occur is: 1. B-D-A-C. 2. B-D-C-A. 3. D-A-B-C. 4. D-C-B-A

Answer: 1. B-D-A-C.

Explanation: If a genetic error occurs during chromosome replication, it will lead to a series of events ranging from:

1) Production of a DNA strand with an altered base sequence.

2) Production of an mRNA strand with an altered base sequence during transcription. This is because mRNA is synthesized by copying the genetic message coded in the DNA.

3). Synthesis of a protein with an altered amino acid sequence during translation, and this eventually leads to

4). The expression of a new inheritable trait in the organism.

rosijanka [135]

Answer:

Recessive

Explanation:

A recessive disorder is expressed in a homozygous genotype only. Most of the recessive disorders are not expressed as the expression of the recessive allele is masked by a dominant allele in the heterozygous state. However, breeding between close relative (inbreeding) increases the homozygosity in the population and allows the expression of recessive alleles that were otherwise not expressed in the population.

According to the given information, the disease is rare and is mostly expressed in the progeny obtained by mating between closely related individuals (the first cousins). Therefore the disease is inherited in an autosomal recessive pattern.

In what ways do humans use diatoms?​
creativ13 [48]

As diatoms are made from silica this makes diatomaceous earth very abrasive, and so the sharpness enhances the particles as a pesticide. Diatoms are also useful in forensic studies. If a person has drowned then diatoms are able to enter the human body.

Which line best represents the level of oxygen gas in the atmosphere during the Proterozoic?
katrin2010 [14]

Explanation:

C- this line shows a gradual increase

Just before the Cambrian explosion, the atmosphere became oxygenated, leading to an explosion of new life in the form of primative blue green algae called cyanobacteria and oxygen dependent organisms in the Proteozoic Eon (2500-541 million years ago). Later, multicellular organisms followed, along with higher levels organization and complex life. Oxygen levels rose from low levels, steadily over this period of time.

Further Explanation:

The rise in O2 gas within the aquatic habitat and atmosphere is attributed to photosynthesis in cyanobacteria which allowed respiring eukaryotes to thrive.

Photosynthesizing cells in blue green algae contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates in the process photosynthesis. This is a chemical pathway that’s integral to producing energy in primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent.

With the evolution of oxygen dependent organisms like Ediacara biota, came respiration in the mitochondria. Eukaryotes utilize glucose along with oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycolysis). Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain and the energy they release is used in pumping H+ to produce ATP from ATP synthase. At the end of the ETC molecules of oxygen accept electrons and protons to form molecules of water.
