In these imprinted cells, the SNRPN transcript overlaps with another gene, called UBE3A, which is transcribed in the opposite di

rection. This means that the region that the RNA polymerase transcribes in these two genes actually overlaps; in some cases, overlapping transcription in opposite directions leads to transcriptional interference, meaning that collisions between the polymerases traveling in opposite directions can interfere with transcription. It is believed that this takes place in this case, meaning that the more SNRPN transcription occurs, the more this disrupts transcription of UBE3A. Based on this information as well as information about the effects of imprinting on SNRPN transcription, which of the following statements about UBE3A transcription would be true?
a. The maternal copy of UBE3A is expressed and the paternal copy is silenced.
b. The paternal copy of UBE3A is expressed and the maternal copy is silenced.
c. Both copies of UBE3A are highly expressed.
d. Both copies of UBE3A are silenced.

Answer:

a. The maternal copy of UBE3A is expressed and the paternal copy is silenced.

Explanation:

When UBE3A chromosome is in neurons, paternal allele is silent and maternal allele is expressed in process of genomic imprinting. In some cases UBE3A is expressed from both paternal and maternal chromosomes. The paternal chromosome is blue whereas maternal chromosome is magenta.

Compare and contrast point mutations and chromosome mutations and explain the basis for classifying a mutation as beneficial, ne
zepelin [54]
<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>

I need to know what physical weathering and chemical weathering is for a science project!
Oksana_A [137]
Ok ok no fret im here to help as best as i can :)
Weathering is a process that breaks down or changes rocks into smaller pieces. Various atmospheric aspects are responsible for weathering processes. Weathering is different from erosion. Erosion is the movement of rock pieces and sediment from one area to another. Weathering is the breaking down of rocks and erosion is a wearing away of rocks. There are two main types of weathering: physical (or mechanical) weathering and chemical weathering. Quite often, both forms of weathering will occur together

Physical weathering is also known as mechanical weathering. This type of weathering occurs when rocks and other landforms are broken down by physical factors in the environment. These physical factors include wind, water, sun, ice and temperature changes

Reil [10]

Answer:

Direct.

Explanation:

An information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

Hence, an information system interacts with the overall system by receiving data in its raw forms and information in a usable format.

In this scenario, Mother Goose Computing, Inc. are currently updating several of their systems. For the genomics division, it's planning to replace the old system by the new one all at once. Thus, this is called a direct conversion.

Direct conversion can be defined as a process which typically involves the establishment and implementation of a new system followed by an immediate discontinuation of the old system all at once. Thus, on a particular date and time, the old system would be discontinued while the new system is immediately adopted for use in the particular organization.

1.how is the sound of thunder created?
Naddik [55]
1. Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. ... From the clouds to a nearby tree or roof, a lightning bolt takes only a few thousandths of a second to split through the air. The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself.
2. thunderstorms mostly occur in rainforests. Some of the most powerful thunderstorms happen in the United States of America.

3. Cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along cold front squall lines.

4. The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.
