Copying genetic information from dna into rna is called __________; using the information contained in mrna to make a polypeptid

Ket [755]

Genetic information from DNA to RNA is called transcription which involves the enzyme RNA polymerase. The DNA is read from 3' to 5' in direction and produces an mRNA (messenger RNA) which contains the genetic data from the DNA. This mRNA strand is further processed in the nucleus (capping and adding a poly-A tail) before being transported to the cytoplasm.

The information contained in mRNA is used to make a polypeptide chain is called translation. This involves the use of ribosomes in the cytoplasm which attach themselves to the mRNA strand then using tRNA (transfer RNA) to add amino acids to the elongating polypeptide depending on the codon in the mRNA.

a. What do the letters R and I represent ? b. What is the genotype of the pink-flowered snapdragons? c. Explain whether the alle

-Dominant- [34]

Answer:

a) R= allele for red colored flower

I= Allele for ivory flowers

b) Genotype of pink flowered plant: RI

c) Incomplete dominance

d) 100%

Explanation:

When the dominant allele is not able to fully mask the expression of the recessive allele in the heterozygous state, it is said to be incomplete dominance. The R and I alleles impart red and ivory color respectively to the flowers of the snapdragon plant. The heterozygous genotype "RI" imparts a pink color to the flowers and therefore, the alleles are said to exhibit incomplete dominance.

The genotype of red-flowered snapdragon plant = RR. The genotype of ivory flowered snapdragon plant= II. When a red-flowered snapdragon plant is crossed with an ivory flowered snapdragon plant, the progeny is heterozygous in nature with the "RI" genotype. The phenotype of the progeny is "Pink flower" since the R allele is incompletely dominant over the allele I.

A client has undergone a left hemicolectomy for bowel cancer. Which activities prevent the occurrence of postoperative pneumonia

Hunter-Best [27]

The measurable activities like Coughing, breathing deeply, frequent repositioning, and using an incentive spirometer are for preventing postoperative pneumonia. Hence, Option C is correct.

<h3></h3><h3>What is postoperative pneumonia?</h3>

Pneumonia is caused by Streptococcus pneumoniae and Haemophilus influenzae leads to infection of the alveoli of lungs.

This type of pneumonia is a rare medical condition happens after local anesthesia has been given to a patient.

The primary causes are the amount of anesthesia given, poor handling of chemicals, the type of anesthesia given to the patient.

To prevent the occurrence of postoperative pneumonia are medicating the patient and use of incentive spirometer. Hence, Option C is correct.
