Increased numbers of CAG repeats in the exon of a gene is associated with certain diseases. In a specific gene, the existing CAG codons are in the 'zero' reading frame, in- frame with the AUG initiation codon. The effect of increased numbers of CAG repeats on the encoded protein is:___________. a. to silence of the gene to generate a truncated protein b. to generate a protein with a run of consecutive glutamines c. to generate a frameshifted protein product d. none of the above

Answers

Answer:

The correct answer is - option b. to generate a protein with a run of consecutive glutamines.

Explanation:

The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.

So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.

A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibit PS I but do not affect PS II (case 2).
Which of the following results is expected?
A)in case 1, only PS I completely loses function; in case 2, no proton gradient is produced.
B)In case 1, only PS I completely loses function; in case 2, a proton gradient is still produced.
C)In case 1, both PS I and PS II completely lose function; in case 2, no proton gradient is produced.
D)In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Answers

Answer:

D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Explanation:

The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.

The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.

In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.

Why is meiosis important in maintaining genetic diversity?

Question 6 options:

A Meiosis creates diversity by cutting each chromosome exactly in half.


B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.


C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.


D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.

Answers

Answer:

We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Explanation:

Brainliest please?

Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.    

Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.

The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.

Other options-

A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.

C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.

D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

Answers

Answer:

c. metallic bond

Explanation:

Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.

The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles of the leg.

Answers

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.

The specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.

The function the eyes performs requires more precise locomotion control than the movement of the limbs require.

For an eye movement to be made, an action potential must be transmitted which makes the sarcomeres of the elastic fibers and z-lines to unit thereby producing movement of the eye. This movement are usually done with almost perfect preciseness.

This is why there are more alpha motor neurons that control eye movement than we have in postural muscles of the leg.

In summary, the specificity and preciseness of eye movement control justifies why the ratio of motor neurons to muscle fibers is greater for muscles controlling eye movement than those in the postural muscles of our leg.
