The given blank can be filled with Cones.

The visual acuity can be defined as the clarity of the vision, it is related to the sharpness and the clearness of the image formed. The vision acuity is determined by the optical and the neural factors, it is dependent on the retinal focus and the sensitivity of the nerve cells and the brain.

The cones are the pointed, thick and short sensory receptors, present in the eye. They are responsible for the color vision and the sharpness or the acuity of the image. They work better in brighter light.

The AUC and AUA codons in mRNA both specify isoleucine. What feature of the genetic code explains this?

Serjik [45]

Answer:

Degeneracy

Explanation:

There are 4 nucleotide bases and they can form a lot of different codons - about 64 different codons

There are only 20/21 amino acids, not enough for each of the codons

As a result, codons have to "double up" and share amino acids because there is only a limited number of these that they can code for

In a nucleotide, the nitrogenous base is attached to the sugar's _____ carbon and the phosphate group is attached to the sugar's

LUCKY_DIMON [66]

Answer:

A. 1' ... 5'

Explanation:

The pentose sugars present in nucleotides have five-carbon structures. Other components of a nucleotide are a phosphate group and a nitrogenous base. The nitrogenous base in a nucleotide can be a purine or pyrimidine. The purine bases are covalently joined to the 1' carbon atom of the pentose sugar at their N-9. The bond between the nitrogenous base and a pentose sugar is called the N-beta glycosyl bond.

Similarly, N-1 of a pyrimidine base is covalently linked to the 1' carbon of the pentose sugar. The phosphate group of a nucleotide is bonded to the 5' carbon of the pentose sugar.
