g In transcription, the 3'-hydroxyl group of the growing RNA strand: Group of answer choices NONE OF THESE binds to the 5' ribos

Tatiana [17]

Answer:

attacks the outermost phosphorous group of the incoming nucleotide.

Explanation:

Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.

HELP! Me!

OLEGan [10]

Answer:

They camouflage

Explanation:

The peppered moths adapt to their surroundings. They blend in with their surroundings to avoid being eaten by their predators. Blending in with their surrounding also helps them to sneak up on and catch their prey.

I'm not too sure why they lay 100 eggs at a time but i think it's because the parents want to increase the survival of their eggs. Eggs sometimes are eaten by other animals and the parents want at least a few to survive.

The data obtained from the meselson–stahl experiment after one generation of replication eliminated the dispersive model of dna

Sedaia [141]

<h2>Given statement is false</h2>

Explanation:

According to dispersive model of DNA replication,DNA molecules are hybrids of parental and daughter DNA;In this model each individual strand is a combination of original and new DNA

Meselson and Stahl did an experiment on DNA replication using E.coli bacteria

E.coli was grown in a medium containing heavy isotope of nitrogen,bacteria took up the nitrogen and used to synthesize new biological molecules,including DNA
It was grown for many generations,the nitrogenous bases of the bacteria's DNA were all labelled with heavy nitrogen
Bacteria were then switched to light nitrogen isotope and allowed to grow for several generations
They then measured the density of the DNA using density gradient centrifugation
This method separates molecules such as DNA into bands by spinning them at high speeds in the presence of another molecule, such as cesium chloride
Each DNA produced two DNA molecules each with one new strand and one old strand called semi conservative replication(half of the parental DNA conserved in daughter DNA)
Each DNA strand act as a template for synthesis of new strand
Hence,dispersive model of DNA was eliminated and semi-conservative model of DNA replication was proved by the above experiment
