-
A. None of these
-
B. Transformer
-
C. Carrier
-
D. Vector
Explanation
A vector is a DNA molecule used to carry a gene of interest into a host cell for cloning.
Common vectors include plasmids, bacteriophages, and cosmids.
نقل سب سے زیادہ ______ سے ملتا جلتا ہے؟
-
A. Translation
-
B. None of these
-
C. Facilitated transport
-
D. DNA replication
Explanation
- Transcription and translation both involve genetic information processing.
- Transcription converts DNA to RNA.
- While translation converts RNA to protein.
-
A. None of these
-
B. Transcription, then translation, then replication
-
C. Replication, then transcription, then translation.
-
D. Replication, then translation, then transcription.
Explanation
Replication copies DNA.
Transcription makes RNA from DNA.
Translation makes proteins from RNA.
پروموٹر سائٹس کس کے لیے ہوتی ہے؟
-
A. Initiation of transcription
-
B. DNA repair
-
C. initiation of replication
-
D. Protein synthesis
Explanation
Promoter sites are specific DNA sequences where RNA polymerase binds to initiate transcription, the process of copying a gene's DNA sequence into RNA.
ایک پولیپپٹائڈ کی ترکیب کے لئے ذمہ دار جین کی فنکشنل یونٹ ______ کہلاتا ہے؟
-
A. Recon
-
B. Gene
-
C. None of these
-
D. Cistron
Explanation
- A cistron is a functional unit of a gene that codes for a single polypeptide chain.
- It is essentially a coding segment of DNA or RNA that defines a specific protein structure.
-
A. Gene
-
B. Chromosome
-
C. Allele
-
D. None of these
Explanation
Alternative forms of a gene which occupy the same position on a chromosome are called alleles.
For example, tallness is a character that is expressed by T and t alleles.
-
A. Genes include long DNA molecules called chromosomes
-
B. Chromosomes include a long molecule of DNA divided into sections called genes
-
C. Chromosomes include genes which are divided into sections called DNA molecules
-
D. Chromosomes are long DNA molecules divided into sections called genes
Explanation
A chromosome is a long, thread-like structure made up of DNA, and within that DNA are smaller segments called genes.
حیاتیاتی معلومات کا بنیادی اکائی کون سا ہے؟
-
A. Species
-
B. Gene
-
C. None of these
-
D. Allele
Explanation
A gene is the basic unit of biological information, carrying instructions to build proteins and determine traits.
Genes are located on DNA and passed from parents to offspring, guiding heredity and development.
-
A. Fungi
-
B. Virus
-
C. Protozoa
-
D. Bacteria
Explanation
Humulin (human insulin) is produced using bacteria through recombinant DNA technology.
