Why aren't there any cures for genetic disorders

1 answer:

7 0

There aren't any cures for genetic disorders because most people are born with genetic disorders. The genetic defect is actually encoded in the cells DNA and it makes it nearly impossible to cure those defects after birth. I hope that this is the answer that has actually come to your desired help.

Which of the following is NOT a beta-lactam antibiotic?

emmainna [20.7K]

Answer:

vancomycin

Explanation:

β-lactam antibiotics are those antibiotic that that contain a beta-lactam ring (the cyclic amide with the nitrogen atom attached to the β-carbon) in their molecular structures. This class of antibiotics is the most commonly used and it includes penicillin derivatives, cephalosporins, monobactams, and carbapenems. The mechanism of action of β-lactam antibiotics is inhibition of cell wall biosynthesis in the bacteria.

pishuonlain [190]

Answer:

Golgi apparatus

Explanation:

Once the protein products are packaged in the endoplasmic reticulum into vesicles that fuse to the Golgi apparatus, these protein products are modified by enzymes. These changes are called post-translational modifications and include the addition of carbohydrates, lipids or some other functional groups. All these modifications are key for protein functionality. After this process is concluded, functional proteins are packaged into vesicles and released to their final destination inside or outside the cell.

n cattle, an autosomal mutation called Dexter produces calves with short stature and short limbs. Embryos that are homozygous fo

timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two: DdRr x DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Others that are either aborted or stillbirths include:

1 ddRR

2 ddRr

1 ddrr
