In which phylum do we see plants with lignin, vascular system but no seeds?

Biology
1 answer:
andre [41]3 years ago
4 0

Answer is the phylum is Pteridophyta. Pteridophytes are first land plants, examples ferns, <em>Lycopodium, Selaginella. </em>Members have liginified cells and developed conducting tissues called vascular system to conduct water and synthesized food. They reproduce through spores, seeds do not develop in pteridophytes.

During ___ the cell uses information from messenger RNA to produce proteins
Elden [556K]

Answer: Translation

Explanation: Translation is a process in which the genetic information encoded in an mRNA molecule is used to make proteins. Translation occurs in the ribosome. The mRNA contains codons which codes for particular amino acids. These codons are read by the ribosome one at a time while the transfer RNA fetches the corresponding amino acid and attaches it to the growing polypeptide chain. Amino acids are monomeric units of proteins. The amino acids sequence produced undergoes some modifications and packaging to form protein.

Write out the steps in the Central Dogma. List where each step occurs in the cell. For each arrow, name the process that the arr
Triss [41]

Answer:

1. The Central Dogma refers to the molecular process by which the DNA is converted into proteins using RNA as intermediate, i.e., DNA (Transcription)-> RNA (Translation) -> Protein.  

2. Localization:

Transcription: within the cell nucleus (in eukaryotic organisms)

Translation: cytoplasm

3. Enzymes :

Transcription: RNA polymerase

Translation: Peptidyl transferase

Explanation:

Transcription is the process by which a segment of DNA (called gene) is used as template to synthesize a messenger RNA (mRNA) by using a specific RNA polymerase enzyme. During translation, this mRNA travels from the cell nucleus to the ribosomes in the cytoplasm, where this sequence (mRNA) is used as template to synthesize a protein. The ribosomes are organelles composed of ribosomal RNA (rRNA) molecules which direct the catalytic steps of protein synthesis, while transference RNAs (tRNAs) are molecules that act as adaptors which link the mRNA template with the corresponding amino acids being incorporated into the protein. The enzyme peptidyl transferase catalyzes the formation of peptide bonds between adjacent amino acids.
