the nontemplate strand of a portion of a gene reads 5'ACTGGTTCA. What will the sequence of the resulting transcript for this por
konstantin123 [22]

Answer:

DNA template sequence:  

5' TGACCAAGT 3'

RNA antisense sequence: 3' UGACCAAGU 5'

>>> RNA sense sequence (transcript) : UGAACCAGU

Explanation:

In the DNA molecule, four types of nitrogenous bases are found: cytosine (C), and guanine (G), adenine (A) and thymine (T). In DNA the bases pair up with each other in the following ways: A pairs with T by two hydrogen bonds, while C pairs with G by three hydrogen bonds. In RNA (i.e., transcript sequence), T is replaced by uracil (U). Moreover, the RNA nucleotide sequence is read in the direction 5' to 3'.

A climate zone is an area that is defined by two main factors. What are they?
MA_775_DIABLO [31]

Answer:

Temperature and precipitation.

Explanation:

Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.

Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.
