The amino acids coded triplets in the 3' to 5' strand on the normalp53 gene of chromosome 13 are lysine, leucine, Glutamine, stop codons.

Explanation:

mRNA is formed by the transcription of DNA strand coding for a gene.

Any mutation in the DNA sequence even a difference of base pair would cause formation of different amino acids and hence altered protein.

The amino acid is formed in the step of translation where codes are read by tRNA on the mRNA strand and correct nucleotide is brought to growing polypeptide chain.

In transcription 3' to 5' strand acts a template strand. The amino acids on the p53 gene of chromosome 17 is

3'TTT AAC GTC ATC 5' Gene sequence

5' AAA UUG CAG UAG 3' mRNA

lysine, leucine, Glutamine, stop

bagirrra123 [75]

Answer: Alarm reaction stage

Explanation:

The General Adaptation Syndrome (GAS) is the 3- stage body response to stress conditions. The three stages include

1) Alarm reaction stage

2) Resistance stage

3) Exhaustion stage

Note that the Alarm reaction stage consist of arousal by the autonomic nervous system, where several involuntary responses such as sweating, tension, raised breathing etc are observed due to hormones released.

Use the key to identify each species. Write the letter of each species (A to G) in the correct

sveticcg [70]

Dichotomous keys are useful to identify organisms according to their morphological traits. The given key provides enough macroscopic morphological traits to identify these Arachnida species.

-----------------------------------------------

A dichotomous key is a significantly useful tool to classify organisms. The key provides an easy and fast way for identification by describing different morphological traits, leading you to the correct taxonomic classification.

The key provides morphological descriptions about different taxonomic groups in an easy way to identify these traits in your individual.

The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

In the exposed example, as the key provides morphological traits, we will separate the organisms into two groups:

the group that has the trait
the group that does not have it.

By recognizing each trait in each of the individuals, we will get to identify the species.

1

(a) Abdomen with a tail --------------------------- The only option is E

(b) Abdomen without a tail ---------------------- All the others A, B, C, D, F, G

2 ---Only for group A, B, C, D, F, G---

(a) Legs much longer than abdomen and cephalothorax ----------A and G

(b) Legs not much longer than abdomen and cephalothorax----- B, C, D, F

3 ---Only for group A, G---

(a) Hairs on the legs -----------------------------------The only option is A

(b) No hairs on the legs ------------------------------ G

4 ---Only for group B, C, D, F---

(a) Cephalothorax or abdomen segmented ----------------The only option is D

(b) Cephalothorax or abdomen not segmented ----------- B, C, F

5 ---Only for group B, C, F---

(a) Abdomen and cephalothorax of the same size --------The only option is F

(b) Abdomen and cephalothorax of different size -------B, C

6 ---Only for group B, C---

(a) Body covered with long hair ----------------------------------The only option is C

(b) Body not covered with hair ------------------------------------B

A → Tegenaria domestica

B → Ixodes hexagonus

C → Tyroglyphus longior

D → Chelifer tuberculatus

E → Abaliella dicranotarsalis

F → Poecilotheria regalis

G → Odielus spinosus
