Which of the following is not a process of asexual reproduction?

Options:
A Budding

Syngamy is the phenomenon of cell formed by fusion. The fused cell has double the content of the individual cell. Syngamy is commonly called fertilization resulting in formation of zygote. Syngamy is commonly seen in sexual reproduction where two gametes fuse to form zygote.
In certain organisms, small buds are produced attached to the parent organism which grow and eventually separate to develop into new organism. Fragmentation is a type of asexual reproduction where the body of the organism breaks into pieces and each piece gives rise to whole new organism. These processes are types of asexual reproduction.

Which of the following is not a property of the genetic code?

Options:
A Non-overlapping
B Ambiguous
C Degeneracy
D Universal

The correct answer is:
Ambiguous

Solution:
Characteristics of the genetic code:
1. It is a triplet code. Each threenucleotide codon in the mRNA specifies one amino acid.
2. It is comma free and mRNA read three bases at a time without skipping any bases.
3. It is non-overlapping/non or ambiguous. Each nucleotide is a part of only one codon and is read only once during translation.
4. It is almost universal. In nearly all organisms, most codons have the same amino acid meaning.
5. It is degenerate, means among 20 amino acids, 18 are encoded by 2 or more codons.
6. The code has start and stop signals. AUG is the usual start signal and defines the open reading frame.
7. Stop signals are codons with no corresponding $t$ RNA. Stop signals are also known as nonsense or chain-terminating codons. There are generally three stop codons: UAG, UAA, and UGA.

Which of the following is not a property of the genetic code?

Options:
A Non-overlapping
B Degeneracy
C Universal
D Ambiguous

The correct answer is:
Ambiguous

Solution:
Genetic code is a set of instructions which help cells to obtain the information in making proteins from the DNA. The work of Khorana and Nirenberg helped decipher the genetic code which is followed by all organisms in protein synthesis. The codes are always in a triplet (codon) form that sequence of three N-bases. More than one codon can represent an amino-acids, hence the codes are considered to be degenerate. Although, each code is specific to only one amino acid and they are non-ambiguous. These triplets are non-overlapping and without any punctuations. The genetic code is universal and same for all variants of organisms from bacteria to whale. The start codon is AUG and stop or terminator codons are UAA, UGA, and UAG.
