Answer:
Earth is the third planet from the Sun at a distance of about 93 million miles (150 million km).
What its saying is:
for the chain chart: list a dangerous weather phenomonon you experienced and list words that specify the weather condition you experienced. For example:
you experienced: hurricane Catrina
Details: Had wrecked my house, was very scared then, other people were scared aswell, etc.
( Note that these details come in handy later for the next part.)
The next part wants you to organize the parts of the story kevin made about his hurricane. as a cheat key, its: 2, 1, 3, 4.
Drafting: Its asking you to make a sentence that describes how you felt during that time. You have to use the I before anything else in order to count for the grade if there is any grade given for this lesson.
The next part just wants you to write a story on teh event that you experienced, in this case the hurricane or other weather condition you have brought up.
Revising and proofreading:
were > was
think > thought
was > we
ever > remove this word
The last part just wants you to check off everything, like a grocery list.
Hope this helped!
Answer:
The correct answer is: C. third nucleotide position.
Explanation:
- Genes located on the chromosomes encodes for proteins.
- A Gene is made up of a Deoxyribonucleotide (DNA) sequence which is transcribed into the messenger Ribonucleotide (mRNA) sequence by the help of RNA polymerase.
- This mRNA sequence is further translated into the amino acid sequence, that folds to form the functional protein, by the help of the Ribosome.
- The Ribosome reads the mRNA sequence in the form of triplets (three nucleotide together) and each such triplet nucleotide codes for an amino acid.
- Each such triplet nucleotide is known as a Codon.
- The Genetic Code is a table which represents the amino acid encoded by each codon.
- However, the Genetic Code is degenerate in nature. This means that one amino acid can be coded by more than one codon.
- This is because, among the the three nucleotide positions in a codon only the first two determine the specificity of the amino acid while the third nucleotide, also called the wobble nucleotide, is not specific. Presence of any nucleotide in the third position of the codon will not alter the amino acid encoded by the codon.
- In the given question, organisms producing homologous protein have similar amino acid sequence but they vary in the corresponding nucleotide sequence of the gene which codes for the homologous protein.
- This is because at the nucleotide level the variation lies in the wobble nucleotide position that occupies the third position in the codon.
Answer: C) Centromeres
Explanation: Centromeres are involved in crossing over, none of the other ones are.
