How do animals survive without cell walls?

Biology
1 answer:
dangina [55]3 years ago
4 0
Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton.

If one strand of DNA has the base sequence TTCCGGAA The complementary strand has which of the following sequence?
Mazyrski [523]

Answer:

If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.

Explanation:

A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other .

The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.

  • <em>Adenine is combined with Thymine A=T </em>
  • <em>Cytosine is complemented with Guanina C≡G </em>

In this way, given a sequence on a DNA strand :

<em>     T-T-C-C-G-G-A-A</em>

The complementary strand will have this sequence:

<em>     A-A-G-G-C-C-T-T</em>

What type of bond occurs between the nucleotide bases in the codon and the anticodon?
Paha777 [63]

Answer:

C. Hydrogen bonds

Explanation:

Anticodon refers to the set of three nucleotides present in tRNA. The anticodon is complementary to the codon of mRNA. The nucleotide bases of anticodon and mRNA codons are paired by hydrogen bonds.

Here, the adenine of anticodon makes the hydrogen bond with the uracil base of codon while the guanine base of anticodon forms the hydrogen bond with the cytosine base of the codon.

There is a specific tRNA with an anticodon complementary to the mRNA codon for each amino acid. For example, the tRNA for phenylalanine has an anticodon 3' AAG 5' and binds to the complementary mRNA codon base via hydrogen bonds.
