The distance from Alexandria to Syene is about 500 miles. On the summer solstice the sun is directly overhead at noon in Syene.

svp [43]

Answer:

Earth circumference is 25000 miles

correct option is 25,000 miles

Explanation:

we have given here Alexandria to Syene distance = 500 miles

the sun is 1/50th of the circumference of the sky (about 7°)

as we know that Earth circumference done by astronomer Eratosthenes in 240 B.C

He observe on a particular time of day ( in noon) during the summer solstice

and there was no shadow in Syene in Egypt so This was verified that the sun must be directly on overhead and not at an angle to the surface of the city at that time

so

In Alexandria he measured the position of sun at the same time and found it to be nearly (1/50)th of a complete circle

it would be 7.2 degree (when we do $\frac{360}{50}$ = 7.2)

so 2 reference points being 2 cities for the sun

all measure circumference = the distance between these two cities × 50

and we have given 500 miles

so

Earth circumference = 500 × 50

Earth circumference is 25000 miles

correct option is 25,000 miles

Predict the product sequence for DNA replication,transcription and translation process using DNA template of TATAATGAAGTTCCGAGGA

Rina8888 [55]

Answer:

Replication: 3' ATATTACTTCAAGGCTCCTATC 5'
Transcription: 3' AUAUUACUUCAAGGCUCCUAUC 5'
Translation: AUA UUA CUU CAA GGC UCC UAU

Explanation:

First of all you need to know that DNA is formed by nitrogenous bases represented by letters (ATCG). The sequence that these letters present in the DNA are the basis for the establishment of the processes of replication, transition and translation. This is because these bases complement each other and make connections between themselves as follows:

Adenine (A) is complementary and makes connections with Timine (T) in DNA and with Uracil (U) in DNA and vice versa.
Guanine (G) connects and is complemented by cytosine (C) and vice versa.

Based on that, we can use the sequence 5'TATAATGAAGTTCCGAGGATAG-3 as a model for DNA replication we can say that the sequence of the new DNA strand would be 3 'ATATTACTTCAAGGCTCCTATC 5', since the new strand is built based on the complementarity of the bases nitrogenous.

This same sequence, when used in replication, for the formation of an RNA molecule, would also use the base complementarity, forming an RNA molecule with the sequence 3 'AUAUUACUUCAAGGCUCCUAUC 5'.

The translation, in turn, would use the RNA sequence to form the amino acids that would form a protein. Each amino acid would be formed by the joining of three nitrogenous bases of the RNA sequence, thus the protein would be formed by the amino acids AUA UUA CUU CAA GGC UCC UAU
