DNA polymerases are capable of editing and error correction, whereas the capacity for error correction in RNA polymerases appear

s to be quite limited. Approximately one error occurs in every 104 to 105 nucleotide incorporated in RNA. Given that a single base error in either replication or transcription can lead to an error in the protein coded by the gene or mRNA. Please suggest a possible explanation for this striking difference.

Explanation:

DNA polymerase replicates the DNA supplied to all new cells produced while RNA polymerase drives DNA copy RNA synthesis. Unless corrected, error in DNA replication could result in the transmission of the error DNA to all next-generation cells.

Protein synthesis error will cause faulty copies of RNA and degraded proteins. To order to ensure the transfer of key genetic information to future generations of cells, failure to DNA replication must be corrected.

Structural proteins that typically assemble into large cables or threads, to provide mechanical support to cells or organisms ar
ollegr [7]

Answer:

Fibrous

Explanation:

Proteins are assembled according to their functions. Fibrous proteins usually provide protection and support to cells. They are made up of polypeptides that have elongated shape and assembles in large cables or threads. These proteins are differentiated from globular proteins by their globular form and repeated units of amino acids.

For example the fibrous proteins involved in horns, hair and nails is alpha-keratin.  Elastin found in skin and ligament is also a fibrous protein. Collagen includes collagen fibrils that have tensile strength of steel is also a fibrous protein found in cartilages and bones.

Hello there,

1.) According to the biomolecular data, we COULD infer that <span>humans are more closely related to chimps than any other apes. 

2.) </span>Based on the cladogram, if moths undergo complete metamorphosis, we would MOST LIKELY infer that <span>butterflies and flies do as well. 

3.) </span>According to the cladogram, which of these were the direct ancestors of the Kingdom Fungi? <span>Protista 

4.) </span>Trey is looking at a cell under the microscope. It is attached to many other cells, and it has a nucleus and membrane bound organelles. It has no cell wall. In which kingdom should this organism be classified? <span>Fungi 

5.) </span>A review of the cladogram shows a common ancestor for these four types of vertebrates. Which statement BEST explains the genetics represented by the cladogram? <span>Lizards and snakes are more genetically alike than lizards and birds. 

Hope this helps

The<br> of the Earth on its axis causes
egoroff_w [7]

Answer:

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere

What are the two supporting evidence of seafloor spreading theory?
sladkih [1.3K]

Answer: Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. This evidence led scientists to look again at Wegener's hypothesis of continental drift.
