Which of the following statements describes the central dogma of molecular biology?
BARSIC [14]
<span>Q1. The answer is A.Biological information in a cell passes from DNAto RNA to proteins. The biological information is the part of DNA. During transcription, DNA is transcribed into RNA which now serves as a template for the synthesis of proteins. Thus, the central dogma of molecular biology describes how biological information in a cell passes from DNA to RNA to proteins.
     
Q2. The answer is D. 46. In a human diploid somatic cell (2n), there are 23 chromosomes present in two copies - 22 pairs of autosomes and 1 pair of sex chromosomes. So, in a normal human karyotype there will be in total 46 chromosomes (23 pairs in 2 copies: 23 × 2 = 46).
   
Q3. The answer is A. inbreeding. Inbreeding is a breed from closely related organisms. Inbreeding causes a decrease of genetic variation by increasing homozygosity. This way, it can cause the genetic defect by bringing two recessive alleles together.</span>

A pea plant with round seeds (RR) is crossbred with another pea plant with wrinkled seeds (rr). What is the probability of produ
Reil [10]

Answer: The probability of producing offspring with genotype Rr is 100%.

Explanation-

Round seed is a dominant trait ( depicted by dominant R allele) whereas wrinkled seed is a recessive trait ( depicted by recessive allele r).

According to the law of segregation of genes, the alleles will separate from one another during gamete formation.

Pea plant with round seeds will produce two gametes that is R and R whereas plant with wrinkled seeds will produce r and r gametes.

When the parents are crossed, they will result in the offspring with genotype Rr ( that will exhibit round seed phenotype).

Refer punnett square.

<h3><u>Answer;</u></h3>

Gene therapy to correct defective genes that cause diseases.

<h3><u>Explanation</u>;</h3>
  • Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.
  • Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.
  • The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.
