*lf a strand has 35% adenine, what percent will be cytosine?

Answers

Answer:15% cytosine

Explanation:We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.

Archaebacteria and eubacteria are classified into different kingdoms, but at one time they were both classified in the Kingdom Monera. Which statement best describes why the classification of these organisms was changed?

A. The kingdom became too large and had to be made into two smaller kingdoms.
B. New biochemical data showed different evolutionary relationships within the kingdom
C. The archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
D. Chromosomal analyses indicated a new genetic combination had arisen within a certain organisms in the kingdom.

Answers

Answer:

I think the option C is correct

The statement best describes the classification of these organisms was changed is the archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.

What are the characteristics of Archaebacteria?

Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.

Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences.

The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.

Complete the table below showing the sequences of DNA, mRNA codons, tRNA anticodons and the amino acids. Remember the genetic code is based on mRNA codons. (il give you brain list if you answer all)

Explanation:

7. UGG 8. GAU 9. AUA 10. phenylalanine 11. aspartate 12. isoleucine

During translation, tRNA adds the correct amino acid to the growing protein, following the mRNA codon sequence. Tryptophan, Lysine, Leucine, Tyrosine.

What is translation?

Translation is the stage in protein synthesis that follows transcription, and occurs in the cytoplasm.

When mRNA leaves the nucleus and moves to the cytoplasm, it meets a free ribosome that is the primary structure for protein synthesis. Ribosomes are composed of two subunits of rRNA associated with different tRNA that carries amino acids.

The ribosome reads mRNA in the 5' to 3' direction, and, according to the codons that are being readen in mRNA, tRNA transfers the correct amino acids to build the polypeptide chain.

Let us remember that the codon is the sequence of three nucleotides present in mRNA. The molecule carriesa a start codon and stop codons.

Each tRNA has two important sites. One of them is the antidocon that couples with the codon of the mRNA molecule. The other site couples with the coded amino acid.

The protein is synthesized from the amino terminus to the carboxy terminus.

In the example,

DNA              mRNA             tRNA             Amino Acid

ACC               UGG                ACC             Tryptophan

TTC                AAG                UUC             Lysine

GAT               CUA                 GAU             Leucine

ATA                UAU                AUA              Tyrosine

Answers

The provided question lacks the options, however, the options associated with the question is as follows;

A. translation

B. cellular respiration

C. active transport of ions

D. replication of chromosomes

Answer:

The correct answer is - D. replication of chromosomes.

Explanation:

During every cell division, either meiosis or mitotic the chromosomal DNA present in the nucleus is needed to be duplicated and the process that involves the duplication of this chromosomal DNA is known as replication of chromosome which takes place during the interphase of the cell division.

All other processes mentioned in the options are not involved or directly not involved in the processes. Translation involves the mRNA in the cytoplasm to produce amino acids with the help of ribosomes. Cellular respiration involves mitochondria and does not require DNA in the process.
