Answer:

Meiosis

Explanation:

Meiosis is the spliting of sex cells or chromosomes through the PMAT phase twice. Mitosis is the splitting of body cells such as skin cells ect. and only goes through PMAT once.

Nadya [2.5K]

Ichthyology is best characterised as Science. None of the other field of studies apply to Ichthyology.

Pseudoscience are beliefs or theories that have been considered scientific. However, they are disapproved scientifically because lack of facts and evidence.

Cryptozoology is study of animals that are rumoured to exist. (Bigfoot, Loch Ness Monster, etc) It is connected with pseudoscience.

Mythology can refer to myths or the study of myths.

As you can see, the study of fish does not apply to any of the area of studies except for Science. Ichthyology applies to Science, because it is a scientific study is different aspects of various species of fish. This includes history, behaviour, and growth.

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid

What might happen if the gametes of a species had

mario62 [17]

Answer:

The chromosome number will not be constant and the person would die.

Explanation:

During gamete formation, half of the chromosomes arise from one parent and the other half from the other parent. This is possible due to the process of meiosis.

If during gamete formation, the number of chromosome does not get reduced, then after fertilization the gamete will have double the number of chromosomes as compared to the parents. Hence, the chromosome number of the person will not remain constant and he/she would die.
