In prokaryotes, a search for genes in a DNA sequence involves scanning the DNA sequence for long open reading frames (that is, r

eading frames uninterrupted by stop codons). What problem can you see with this approach in eukaryotes?

Answer:

DNA in eukaryotes have introns which are the non-coding sequences and are spliced out of primary transcript. They are not present in mature mRNA.

Explanation:

The reading frame of 50 or more nucleotides without any termination codon in between is called an open reading frame. The long open reading frames mostly represent protein-coding genes.

Hence, long open reading frames are searched for in order to find the genes. The presence of introns in eukaryotic DNA does not allow the application of this approach to find genes in eukaryotes.

The post-transcriptional modification of the primary transcript removes the introns. Hence, a mature mRNA does not have introns. Therefore, introns do not contain open reading frames.

Consider this animal cell. What is the function of the organelles that are labeled F? to temporarily store water, waste products
Temka [501]

The organelle labeled 'F' in the given diagram is Endoplasmic reticulum. The main function ER is to move proteins and other substances through the cell.

Further Explanation:

In biology, Endoplasmic Reticulum (ER) is a continuous membrane system that makes a series of flattened sacs inside cytoplasm of the eukaryotic cells and provides multiple functions. All the eukaryotic cells consist of endoplasmic reticulum. On the basis of their functional and physical characteristics they are divides into two types:

  • Smooth endoplasmic reticulum: They do not consist of any ribosome and synthesize lipids.
  • Rough endoplasmic reticulum: they consist of the ribosome on their outer surface because of this their surface is rough. They help in synthesizing protein.

Important functions of the ER are:

  • Synthesis protein
  • Protein folding
  • Protein modification
  • Transport of protein

Golgi apparatus is a folded membranous structure present in eukaryotic cells and has vital intracellular functions. It has flattened sacs in the membrane which are referred to as cisternae. ER synthesizes protein and transfers it to the Golgi apparatus.

Scientists are trying to reduce the amounts of carbon dioxide and methane that enter the atmosphere. Which statement explains wh
Marat540 [252]
As a result in the attempts to reduce the amounts of carbon dioxide and methane, green house gases will lessen and the ozone layer will slowly stop being damaged. Global Warming may also calm down as the main cause for global warming is the exposure of Greenhouse gases to the ozone layer.

Hope this helps!

Which waste management process involves the burning of solid waste?
damaskus [11]

Solid waste Incineration management process involves the burning of solid waste

<u>Explanation:</u>

Incineration is the process of burning of solid wastes. It is one of the processes of solid waste management. In this process, combustion of organic and inorganic wastes takes place that leads to the formation of ash, heat and flue gases. Ash is composed of inorganic constituents.

The heat generated during this process can be used to generate electricity. The process is carried out by Incinerators. Incinerators does not completely replace landfilling but it reduces the volume of disposal of the wastes.
