How does natural selection affect populations?

1 answer:

5 0

Answer:

Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.

Molecule 1 has the nitrogenous base sequence TCA AGT. Which set of bases in Molecule 2 can bond to that sequence in a complement

serious [3.7K]

Complete question:

Molecule 1 has the nitrogenous base sequence TCA AGT. Which set of bases in Molecule 2 can bond to that sequence in a complementary way?

a. UCAAGU

B. AGTACA

C. AGUUCA

D. UCAATA

Answer:

C. AGUUCA

Explanation:

DNA template strand and the corresponding RNA have complementary sequences. Adenine in the DNA template strand pairs with "uracil" base of RNA while cytosine pairs with its "guanine" base. Similarly, thymine base in DNA template strand pairs with "adenine" base in the RNA. This occurs since RNA does not have a thymine base. RNA has uracil base instead. Therefore, the molecule 1 with sequence TCA AGT would bind to the molecule 2 with the " AGU UCA" sequence.

Molecule 1: DNA template: TCA AGT

Molecule 2: mRNA: AGUUCA
