those are nucleotides

since all three of them contain deoxyribose (because there's only one hydroxil group) they are DNA nucleotides

the first nucleotide has cytosine as it's nitrogenous base

the second nucleotide has adenine as it's nitrogenous base

the third nucleotide has thymine as it's nitrogenous base

A single strand of DNA helix consists of 100 nitrogenous base pairs. On one strand, 36 of the bases are adenine and 24 are cytos
Katena32 [7]
Hello!

For the complementary strand of DNA, 36 Thymine bases and 24 Guanine bases would complete the proper base pairing. 

This is given by the concept of complementarity. A base in DNA has complementarity with only one other base. This complementarity is produced by hydrogen bond interactions.

For DNA, Adenine couples with Thymine and Cytosine couples with Guanine. So the 36 adenine bases will couple with 35 thymine bases, and so on. 

Have a nice day!

What is the function of the subplate neurons? Choose the correct option.
Semmy [17]

Answer: C) The subplate neurons attract the appropriate thalamic axons to the different parts.

Explanation:

Subplate neurons are the first developed neurons can be found in the cortex of mammals. These neurons disappear during the process of postnatal development and due to functional maturation.

These neurons are sensitive to the injury, when the humans experience cognitive and motor defects.

These neurons attract the thalamic axons and receive the synaptic inputs through the thalamic axons thus helps in establishing the link between the thalamic axons and the target layer IV. The signals are distributed from the thalamic axons to different parts of the body.

6. Read the statement from a scientific researcher. Many organisms depend on other organisms to live,
Free_Kalibri [48]

the argument that the researcher supports in this statement is that the Viruses are nonliving

Answer : Option C

<u>Explanation:</u>

Viruses are organic structures and they are often termed as "organisms at the end of life". Virus is not considered a living as it does not have a biological machinery to replicate.It is a parasite and it needs a host to replicate.

The virus tries its entry through the wounds, respiratory tracts and by passing through insects.

The complete virus particle is known as virion which consists of a nucleic acid surrounded by a capsid, Virus first attach themselves to a host through their surface.
