If one strand of DNA has a nucleotide base sequence of TCAGGTCCATAT, What is its complement base sequence? If the above is the DNA template strand, what is the corresponding RNA nucleotide base sequence? How many amino acids are coded for on the segment of RNA?

This is more biology or genetics than anthropology. These letters do indeed stand for nitrogeneous bases, but you need to know the rules for how the hydrogen bonds work. These bases are always paired up in the same fashion.

For DNA, adenine and cytosine always travel together as do cytosine and guanine. For RNA, you still have cytosine and guanine coupled together. However, RNA has a base known as uracil instead of thymine that bonds with adenine. I can not remember how exactly the processes of transcription and translation assemble protiens from amino acids, but this is something that I never had to memorize. To get you started, just remember that DNA is the master blueprint that sends out messenger RNA which in turn sends out transfer RNA.

Ted, I will be happy to check your work. As Brandon pointed out, the complements are well known, and are in his post.

To find the complement base sequence of a DNA strand, we need to determine the complementary base for each nucleotide. In DNA, adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G).

Given the DNA sequence: TCAGGTCCATAT

The complementary bases are:
T - A
C - G
A - T
G - C
G - C
T - A
C - G
C - G
A - T
T - A

Therefore, the complement base sequence is: AGTCCAGGTATA

To obtain the corresponding RNA nucleotide base sequence, we simply replace thymine (T) with uracil (U) since RNA uses uracil instead of thymine.

The corresponding RNA nucleotide base sequence will be: AGUCCAGGUAUA

To determine the number of amino acids coded for on the segment of RNA, we need to translate the RNA sequence using the genetic code. Each set of three RNA nucleotides, called a codon, codes for a specific amino acid.

Using the RNA sequence: AGU CCA GGU AUA

We break it into codons: AGU - CCA - GGU - AUA

Looking up each codon in the genetic code, we find:

AGU codes for serine (Ser)
CCA codes for proline (Pro)
GGU codes for glycine (Gly)
AUA codes for isoleucine (Ile)

Therefore, the segment of RNA codes for four amino acids: serine, proline, glycine, and isoleucine.
