A set of identical twins are together in an introductory biology class. The unit of study is DNA and its structure. The teacher

Hunter-Best [27]

In identical twins, alleles are identical and the order of the bases on the interior of the DNA molecule is identical (Options C and E). It is because genetic material is identical.

<h3>What are identical twins?</h3>

Identical twins refer to individuals produced by the same zygote cell, i.e., they are monozygotic twins.

Since these individuals are produced by the same zygote cell, their genetic material (DNA) will be identical.

Identical twins are useful to understand the exact role of genetics and environment in a given phenotypic trait.

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing what?

Mashutka [201]

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing "an influx of Cl-".

<u>Explanation:</u>

The neurotransmitters which have inhibitory influence on the neuron are termed as "Inhibitory neurotransmitters". The major inhibitory neurotransmitters involve serotonin and gamma-aminobutyric acid (GABA) in the brain and brain stem (spinal cord) respectively.

GABA uptake is temperature and ion-dependent as require both $N a^{+}$ and $C l^{-}$ . Even glycine transporters are also members of the large family of $N a^{+} / C l^{-}$ dependent neurotransmitter transporters. Both of them with the GABA transporters share approximately 50% sequence identity.
