Q50

Process of program cell death is also known as _______.

A) Necrosis
B) Restoration
C) Autophagic
D) Apoptosis

AI Explanation

Programmed cell death is called apoptosis. It is a regulated process that removes damaged or unnecessary cells in multicellular organisms.

Q51

Which statement is true for protein sequencing technology?

A) Obtaining reads is difficult and assembly of those reads is easy
B) Obtaining reads is easy and assembly of those reads is difficult
C) Obtaining reads and their assembly both is difficult
D) Obtaining reads and their assembly both is easy

AI Explanation

Modern sequencing technologies can generate large numbers of sequence reads efficiently. The major computational challenge is assembling these short, overlapping reads into the correct complete sequence.

Q52

The building block of protein is _________.

A) RNA
B) DNA
C) Amino Acids
D) Gene

AI Explanation

Amino acids are the basic building blocks of proteins. They are joined together by peptide bonds to form polypeptide chains.

Q53

Bacterial Artificial Chromosomes fragment insert size is _______.

A) 25 kpb
B) 150 kb
C) 100 kpb
D) 50 kpb

AI Explanation

Bacterial Artificial Chromosomes (BACs) can accommodate relatively large DNA inserts, typically around 100–300 kb. A commonly cited BAC insert size is approximately 150 kb.

Q54

ORFs within a single genomic sequence may overlap since there are ________ possible reading frames

A) 1
B) 6
C) 2
D) 3

AI Explanation

A double-stranded DNA sequence has six possible reading frames: three on each strand. ORFs can therefore overlap when they occur in different reading frames.

Q55

Eukaryotic gene is called split gene because it is splitted into Exons and Introns

A) False
B) True
C)
D)

AI Explanation

Eukaryotic genes are called split genes because their coding regions (exons) are interrupted by non-coding introns. During RNA processing, introns are removed and exons are joined together.

Q56

How many reading frames must be considered for a given double-stranded DNA sequence.

A) Three
B) Two
C) Six
D) Five

AI Explanation

A double-stranded DNA molecule has three possible reading frames on each strand. Therefore, a total of six reading frames must be considered.

Q57

in Open Reading frames of a single genomic sequence ____ sequence are in forward direction whereas ___ sequence are in reverse direction.

A) 2,4
B) 4,2
C) 3,3
D) 5,1

AI Explanation

There are three possible reading frames in the forward direction and three in the reverse direction. Thus, a double-stranded DNA sequence has six possible reading frames in total.

Q58

Which one is a start codon.

A) AUG
B) UAG
C) UAA
D) UGA

AI Explanation

AUG is the standard start codon and codes for methionine in the genetic code. UAG, UAA, and UGA are stop codons.

Q59

of the human genome is so calledJunk DNA

A) 96-97%
B) 2-4%
C) 40%
D) 86.14%

AI Explanation

Only a small fraction of the human genome directly codes for proteins, while a much larger portion has historically been referred to as non-coding or 'junk' DNA. In the context of this question, the expected answer is approximately 96–97%.

Q60

__________ of the human genome is so called coding sequence

A) 86%
B) 96-97%
C) 40%
D) 2-4%

AI Explanation

Only a small fraction of the human genome consists of protein-coding sequences. Protein-coding exons account for roughly 1-2% of the genome, and this course question gives the broader expected range as 2-4%.

Q61

96-97% of the human genome is so called Junk DNA

A) True
B) False
C)
D)

AI Explanation

In the context of traditional genome classification, approximately 96-97% of the human genome is described as non-coding or 'junk' DNA. This term is historical, since many non-coding regions are now known to have important regulatory or other functions.

BIF501 Final Term AI Solved

Q62

The most conserved part of a gene is _______

A) Promoter
B) Intron
C) UTR
D) Exon

AI Explanation

Exons are generally more conserved than introns because they contain coding information that is subject to functional constraints. Therefore, the exon is the expected answer among the listed choices.
