What is the building block of DNA?
Bogdan [553]
Deoxyribonucleoside Triphosphate, which is the more specific form of Deoxyribonucletides.

When DNA is synthesised by DNA polymerase by complimentary base pairing, 2 phosphate groups from Deoxyribonucleoside Triphosphate breaks away, releasing energy from the binding of the Deoxyribonucleotide to the adjacent Deoxyribonucleotide molecule via phosphodiester bond. These molecules will be called Deoxyribonucleoside Monophosphates.

Thus, the general name of the building block of DNA is Deoxyribonucleotide, and the more specific names depend on at which stage of DNA replication you are referring to.

Hope this helps! :)

Which part of your brain is essential for receiving information that you are moving your legs?
stealth61 [152]

Motor coretex is essential for receiving information that you are moving your legs.

<h3>What is motor cortex?</h3>
  • The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe.
  • The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
  • The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior.
  • For the execution of movements to be precise, coordinated muscle activation patterns are required.

What is the purpose of using reverse transcription
Angelina_Jolie [31]

Answer:

reverse transcriptase (RT) is an enzymeused to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. Reverse transcriptases are used by retroviruses to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes, and by some non-retroviruses such as the hepatitis B virus, a member of the Hepadnaviridae.

Which of the following statements correctly identifies the location of the hydrogens bonds in DNA
asambeis [7]

Answer:

This question is incomplete as it lacks options. However, it can be answered based on general knowledge of the DNA structure.

Hydrogen bonds in a DNA are located between the nucleotides that holds the double stranded DNA molecules.

Explanation:

Deoxyribonucleic acid (DNA) is the genetic material in living cells. The DNA molecule is made up of nucleotides monomers. However, since the DNA molecule is double-stranded, the nucleotides are of two chains composed of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

The two chains of nucleotides in a DNA molecule are called strands. Each strand is bonded to one another by the nucleotides using complementary base pairing i.e. A-T, G-C. The bonds between the nucleotidew of each strand is called HYDROGEN BOND.

Hence, HYDROGEN BONDS in a DNA molecule is located in between two nucleotides of each strand. That is, hydrogen bond holds Adenine to Thymine and Guanine to Cytosine.
