Answer:
Codons after the mutation are not exactly the same as before mutation, because one base was deleted, changing the sequence of codons.
Codons before mutation: ATG TGC GAA ACT TTG GCT
<em>Only the first one (ATG) might coincide with one of the codons before mutation. </em>
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the DNI or mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are a total of 64 codons. 61 codify amino acids, one of these amino acids is also the start point of protein synthesis, and the left three codons are stopping translation points.
The Sequence before mutation ATGCTGCGAAACTTTGGCTGA
Codons: ATG CTG CGA AAC TTT GGC TGA
The Sequence after mutation ATGTGCGAAACTTTGGCTGA
Codons: ATG TGC GAA ACT TTG GCT
<em>Only the first one (ATG) might coincide with one of the codons before mutation. </em>
The tRNAs contain I sound that base pair A C U advantageous to the species rabbit
Answer:
yes, over time pieces of an animals life cycle can change and adapt to help them survive in different environments that doesn't happen overnight. In a frogs life cycle they develop into a frog from an egg. frogs have adapted to become what they are today and if I where to make a prediction it would be that frogs at one point lived solely in water based on the way they grow and develop in there life cycle. having a life cycle means there's room for improvement and tiny adjustments can be Made as a defense mechanism that develops over the course of many froggy life cycles.
Answer/Explanation:
EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.
A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.
Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not.
Prokaryotic Cell
Unicellular
Lysosomes and Peroxisomes absent
Microtubules absent
Endoplasmic reticulum absent
eukaryotic Cell
Multicellular
Lysosomes and Peroxisomes present
Microtubules present
Endoplasmic reticulum present
