Answer:
The answer is the VPg Protein.
Explanation:
The question is incomplete, here is the full question:
Poliovirus is a positive-sense RNA virus of the picornavirus group. At its 5' end, the RNA genome has a viral protein (VPg) instead of a 5' cap. This is followed by a nontranslated leader sequence, and then a single long protein coding region (~7,000 nucleotides), followed by a poly-A tail. Observations were made that used radioactive amino acid analogues. Short period use of the radioactive amino acids result in labeling of only very long proteins, while longer periods of labeling result in several different short polypeptides.
What part of the poliovirus would first interact with host cell ribosomes to mediate translation?
A) the poly-A tail
B) the leader sequence
C) the VPg protein
The part of the host cell ribosome that the poliovirus would interact first is the VPg protein because the poliovirus has to affect the RNA to be able to replicate it's own DNA and the VPg protein is attached to the RNA's 5' end.
I hope this helps.
Answer: The phototropic response occurs because greater quantities of auxin are distributed to the side away from the light than to the side toward it, causing the shaded side to elongate more strongly and thus curve the stem toward the light
The answer is; D
The structure is formed by the vascular cambium. In dicots, the phloem forms around the xylem hence the xylem forms the wood of the plant while the phloems form the bark. The cambium present between primary xylem and primary phloem continues to divide to form the secondary vascular tissues.
Answer:
2n=46(duplicated)
Explanation:
Prior to cell division, which can either be meiotic or mitotic, the DNA content of the cell gets doubled in the Synthesis phase of the Interphase stage. In humans like myself, our cells consist of 23 pairs of chromosomes or 46 chromosomes. The DNA doubles in order for each daughter cell to get the correct number of genetic material.
After the S-phase, the chromosome number in the human cell does not change, just that each individual chromosome gets replicated or duplicated to form sister chromatids. Therefore, the human cell will contain 46 duplicated chromosomes or 92 sister chromatids after Synthesis phase and before the meiotic division.
Note that, humans are diploid organisms (2n) i.e. two set of chromosomes. Hence, they undergo meiosis to reduce their ploidy level from diploid (2n=46) to haploid (n=23).
Answer:
D Anaerobic respiration
Explanation:
The product of anaerobic respiration is the formation of either lactic acid (lactate) or ethyl alcohol as a waste product.
- Anaerobic respiration is a process that occurs in the absence of oxygen gas.
- When oxygen is lacking in cells, glcolytic process follows the anaerobic path way.
- This process produces very little energy for the body.
- During a period of intense exercise, anaerobic respiration usually occurs.
