Answer;

Adjustment knobs are used to focus light in a light microscope.

Explanation;

-A light microscope is an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye, or in finer detail than the naked eye allows.

-Illuminator is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base. Condenser is used to collect and focus the light from the illuminator on to the specimen.

As for function DNA is basically a string of genes and RNA is what converts the information in the DNA into proteins. DNA is the control molecule of the cell and sits in the nucleus. It is made of two strands, connected by hydrogen bonds. Each strand is made of nucleotides.

VLD [36.1K]
<h2>Answer:</h2>

AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.

Which statement correctly describes other ways in which nebulae and stars are different? A. A star always has a higher density t
wel

The answer is; A

Nebulae are clouds of dust and gas in space. When local areas in nebulae start to collapse under their own weight and fusion begins, a star is born. This, therefore, means that a star is denser than nebulae because it requires that atoms fuse for it to form. Fusion creates heavier atoms from light atoms.

Why is it important to have MET at the beginning of mRNA?
astra-53 [7]
The Beginning of mRNA Is Not Translated
Interestingly, not all regions of an mRNA molecule correspond to particular amino acids. In particular, there is an area near the 5' end of the molecule that is known as the untranslated region (UTR) or leader sequence. This portion of mRNA is located between the first nucleotide that is transcribed and the start codon (AUG) of the coding region, and it does not affect the sequence of amino acids in a protein (Figure 3).

So, what is the purpose of the UTR? It turns out that the leader sequence is important because it contains a ribosome-binding site. In bacteria, this site is known as the Shine-Dalgarno box (AGGAGG), after scientists John Shine and Lynn Dalgarno, who first characterized it. A similar site in vertebrates was characterized by Marilyn Kozak and is thus known as the Kozak box. In bacterial mRNA, the 5' UTR is normally short; in human mRNA, the median length of the 5' UTR is about 170 nucleotides. If the leader is long, it may contain regulatory sequences, including binding sites for proteins, that can affect the stability of the mRNA or the efficiency of its translation.
