Answers

Answer 1

The backbone of DNA and RNA is composed of sugar and phosphate.

DNA is double stranded due to interactions between adenine, cytosine, guanine, and thymine, which are nitrogenous bases.

Uracil is a nitrogenous base that is only used with RNA.

The backbone of DNA and RNA is composed of sugar and phosphate groups. The sugar is the 3' end, and the phosphate is the 5' end of each nucleotide in the DNA. In DNA, sugar is called deoxyribose, which is a cyclic pentose (5-carbon sugar). In RNA, sugar is a ribose.

The nitrogen bases interact with each other. The two strands are held together by hydrogen bonds between the complementary bases, adenine with thymine, and cytosine with guanine.

Uracil is a nitrogen base found only in the arm and is a pyrimidine that replaces the thymine base.

why are chromosomes cut into fragments for sequencing?

Answers

Prior to DNA sequencing, chromosomes are broken up because only about 500 bases can be reliably called by DNA sequencing reactions.

Only roughly 500 DNA bases can be properly determined by a DNA sequencing process. The DNA of a cell is broken into relatively big chunks using a technique called map-based sequencing. After a certain length, it becomes challenging to determine the precise base or nucleotide. This is due to the fact that the length of the DNA strand and base quality are inversely related. Enzymatic DNA fragmentation techniques use enzymes to break intact DNA and long sequences into perfect fragments for sequencing, producing clearer findings than subdividing longer DNA sequences into smaller bits before sequencing. Transposase, restriction, and nicking enzymes are some of the enzyme-based techniques for DNA fragmentation for sequencing.

These small crustaceans also referred to as whale lice or cyamids, feed on the whales' pores and skin. Incapable of swimming or surviving inside the open water, they tour from one whale to another by direct contact.\

Whale Cyamids are outside parasites that stay at the frame floor of such marine mammals as whales, dolphins, and porpoises. They take shelter in pores and skin lesions, genital folds, nostrils, eyes, and different external orifices, feeding on host tissue or fluid secretions.

After transformation of e. Coli with pglo, why are the cells grown in lb broth for 20 minutes before plating on amp plates?.

Answers

After transformation of E.Coli with pGLO, It takes 20 minutes to transcribe and translate the Green Fluorescent Protein.

Before RNA polymerase can bind to the Arabinose promoter, it must wait at least 20 minutes. There is a 20-minute phenotypic lag before the b-lactamase gene for Amp resistance can be expressed. The pGLO plasmid contains a gene (bla or ampR) encoding a protein known as -lactamase, which hydrolyzes antibiotics with a-lactam ring and renders host cells resistant to compounds such as ampicillin.

Pyramid of energy is the diagrammatic representation of the transfer of energy at each trophic level in a food chain. The pyramid of energy is always upright. This is because the organism at the lowermost level has the maximum energy and the organism at the topmost level will have the least.

10% rule of energy transfer states that only 10 % of the total energy is transferred from one organism to another during a food chain. The organism at first trophic level, i.e. plants will also be able to absorb only 10% of the total sun's energy.

During transcript elongation, RNA polymerase II may become halted, in which case the ternary complex is unaffected but additional RNA synthesis is prevented. The emerging transcript needs to be split off at the 3' end in order to release arrest.

Transcription continues from the freshly exposed 3' end as 7–17 nt RNAs are freed. The transcript cleavage reaction is substantially stimulated by factor SII, which boosts elongation efficiency. Here, we demonstrate how the addition of pyrophosphate can likewise result in the release of an arrest.

Dna replication begins at a site called the origin of replication, forming a bubble, which is followed by a __________, where parental strands are unwound by __________.

Answers

DNA replication begins at a site called the origin of replication, forming a bubble, which is followed by a replication fork, where parental strands are unwound by helicases.

Each time a cell divides, the two resulting daughter cells must contain the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

Replication occurs in three major steps: the opening of the double helix and the separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.

DNA helicases catalyze the disruption of the hydrogen bonds that hold the two strands of double-stranded DNA together. The replication fork is a multiprotein complex with helicase and DNA synthesis activities.
