Spiders have malpighian tubules to absorb salts and wastes while humans have microscopic subunits in the kidneys called nephrons to filter blood. Malpighian tubules remove wastes from insects by producing urine and solid nitrogenous waste, which are then excreted from the body.

What is the basic building block of all living things?

alisha [4.7K]

Answer:

<h3> $\huge \boxed{ \mathbb{ \bold{ \purple{ \: cell}}}}$ </h3>

Explanation:

All the living organisms on this Earth are made up of microscopic units called cells. It is basic structural unit for all the organisms. The cells are the building block of all the living organisms. Our body is composed of trillion of cells. They carry out the functional activities of our life. A cell can be defined as a basic , structural and functional unit of life capable of independent existence. The cell was first discovered by Robert Hooke in 1665 AD. As we know that all the living organisms are made up of cells. These cells are developed as a result of a division of pre-existing cells. All the cells are same in chemical composition and metabolic processes. The function of an organism as a whole is the outcome of combined activities and interactions of the constituent cells. The cell is known as the fundamental , structural and functional unit of life.

Hope I helped!

Best regards!

Recall that DNA and RNA are synthesized only in the 5'→3' direction and that DNA and RNA sequences are written in the 5'→3' dire

aleksley [76]

Answer:

The Transcription mRNA

5'- AUG-CCC-GUU-UGG-AGA-UCG-GGU-UAC-AGC-UAG-3'

The translation product

5' Met-Pro-Val-Trp-Arg-Ser-Gly-Tyr-Ser-3'

Explanation:

Transcription is a process which transcripts the DNA to a molecule called mRNA or messenger RNA which contains code for the synthesis of amino acids.

The RNA nucleotide base pairs are added in the same way as in the DNA that is guanine will bind cytosine but adenine will bind uracil instead of thymine.

Since the start codon is AUG which codes for methionine and stop codons could be UAG, UAA or UGA which do not code for the amino acids during translation.

In the given question,

Looking for the start codon which is AUG in the template strand is found and the transcript mRNA thus will be coded as

Template strand

3' AACTT-TACGGGCAAACCTCTAGCCCAATGTCGATCAGTTTC 5'

The Transcription mRNA

5'- AUG-CCC-GUU-UGG-AGA-UCG-GGU-UAC-AGC-UAG-3'

The translation product

5' Met-Pro-Val-Trp-Arg-Ser-Gly-Tyr-Ser-3'
