Answer:

D) wild-type 5’-AUGCAUACAUUGGAGUGA-3’ mutant 5’-AUGCAUACAUCUGGAGUGA-3’ is the right answer

Explanation:

frame shift mutation is that mutation in which change in nucleotide sequence ( deletion or insertion) changes the encoding amino acid sequences.

wild-type 5’-AUGCAUACAUUGGAGUGA-3 encode MHTLE- protein sequence while

5’-AUGCAUACAUCUGGAGUGA-3’ encode MHTSGV.

in this option there is clear difference between the encoding amino acid sequence

.in option A and B, there are addition and deletion of amino acids because of addition of nucleotide.

The layer of epidermis where most cells have stopped dividing and started making large amounts of keratin is the

Hunter-Best [27]

Answer:

Stratum Granulosum

Explanation:

The stratum granulosum is a layer of the epidermis and consists of four to six cell layers. The keratinocyte appearance changes in the cell layers of stratum granulosum as some cells stop dividing and the process of keratinization starts. Keratinization includes filling the cells with the protein keratin. During keratinization, the cells flatten, and the disintegration of their nuclei and organelles occur.

Due to the loss of the nucleus, these cells cannot divide and become dead. The keratinized cells accumulate keratohyalin granules and lamellar granules. The cells of this layer have thick plasma membrane due to the binding of cytosol proteins bind to the inner membrane face and coating of the external surface of the membrane by lipids of lamellar granules.

The _____ relies upon radioactive sugar that is injected into the body to form representations of the brain.

jenyasd209 [6]

Answer is Positron Emission Tomography.

Positron emission tomography (PET) is an imaging test based on nuclear medicine. In PET imaging a small amount of liquid radioactive material such as simple sugar (glucose) called fluorodeoxyglucose (FDG) is injected into the bloodstream. It is accumulated in the body and emit gamma rays which are detected by PET. Many diseases such as cancers, brain diseases and heart diseases are diagnosed by the PET imaging.

The statement that provides evidence of the common ancestry of all life is near universality of the genetic code (option A).

<h3>What is the genetic code?</h3>

Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.

The genetic code has the following characteristics:

The genetic code is universal i.e all known living organisms use the same genetic code.
The genetic code is unambiguous i.e. each codon codes for just one amino acid (or start or stop)
The genetic code is redundant i.e. most amino acids are encoded by more than one codon.

Therefore, the statement that provides evidence of the common ancestry of all life is near universality of the genetic code.
